Mastering the ABCs of Doubles Play

In doubles tennis, mastering the fundamentals of net play is essential to gaining a competitive edge. Playing the net effectively involves more than quick reflexes; it requires strategic awareness and precise movements that keep you engaged and positioned to impact the point.

Known as the ABCs of doubles play, there are three core principles — where you look, how you respond to your partner’s shots, and how you get out of harm’s way — provide a solid foundation for any player looking to improve their doubles game.

Below, we delve into each principal in detail, illustrating how these techniques can help you win more points, avoid common errors, and enhance your overall enjoyment on court.

The ABCs of Playing Doubles

A. Where You Look: While at the net, always keep your focus forward. When the ball is in your partner’s court, avoid the temptation to look back at them. Instead, concentrate on watching the opposing net player, as this allows you to anticipate any interception attempts or poaches they might make. When the ball is in the opponents’ court, shift your focus to the player hitting the ball, usually the back player. This continual scanning helps you stay engaged and be ready to play.

 

B. How You Respond to Your Partner’s Shots: Your positioning and readiness at the net should be influenced by your partner’s shots. For instance, when your partner hits a shot that may be intercepted, you need to prepare to defend against an immediate return. This often involves either stepping forward to challenge the shot or stepping back to give yourself reaction time. Reading the opponent’s net player’s body language can give clues on their intent, allowing you to adjust your position proactively.

 

 

C. How You Get Out of Harm’s Way: In doubles, standing at the net can put you in the line of fire. If the opposing net player is about to hit a hard shot directly toward you, it’s crucial to get out of the way safely. Instead of backpedaling, which is less stable, practice a quick side step toward the sideline. This pivot not only keeps you safe but also helps you concede the point with minimal risk of injury if the shot is unavoidable.

 

These essential principles enhance both your effectiveness and safety at the net, maximizing your ability to contribute to each point without unnecessary risk.

The Tennis Parent’s Bible

Most parents invest significant time, money, and energy into developing their children’s fundamental tennis strokes, primarily focusing on “how to hit the ball.”

However, in today’s competitive game, lack of success often stems not from technical shortcomings but from an insufficient understanding of “how to play.” Building a game based on a child’s unique strengths—such as their size, strength, and speed—is crucial. Moreover, many young players lack the mental and emotional development needed to handle adversity, disappointments, injuries, and losses. Championship tennis, in many ways, mirrors life on a grand scale.

Frank Giampaolo’s *The Tennis Parent’s Bible* is an invaluable resource, guiding parents and coaches through the mental and emotional complexities of nurturing a tennis athlete. Despite being published some time ago, its advice remains timeless and highly relevant.

This comprehensive guide equips parents to become world-class tennis supporters. After all, parents need to learn and grow too!

I can relate. One of my sons was a top-ranked junior player in Australia (#1 in New South Wales) before we relocated to the U.S. Competitive tennis is undoubtedly a demanding journey for kids.

Why Is My Game So Inconsistent, Especially as I Get Older?

A question we hear often is why performance can vary so much—especially as we age.

What’s the common thread amid changing conditions, fresh tennis balls, and different opponent styles? It’s your ability to watch the ball. In fact, research shows that 90% of errors result from players not tracking the ball effectively.

The good news? It’s never too late (or too early) to refine your ball-watching skills. Here are a few essential tips to help you focus better and stabilize your performance.

1. Identify Your Dominant Eye

Most players have a dominant eye that influences shot preference, often favoring the forehand side. Knowing which eye is dominant can help you understand tendencies in your game. How do you determine eye dominance? Try this: extend your arm, make a small circle with your fingers, and focus on a distant object through the circle. Close one eye at a time; the eye that keeps the object centered is your dominant eye.

2. Align for Better Tracking

To minimize the effects of eye dominance, position yourself at a right angle to the incoming ball’s direction, particularly on returns and volleys. If you watch players like the pros,  you’ll notice how they adjust their return positions depending on whether they’re on the forehand or backhand side.

3. Move Your Eyes, Not Your Head

Shifting your head to track the ball can delay shot preparation, causing rushed or off-balance strokes. Train yourself to track the ball with your eyes, keeping your head steady to save valuable milliseconds in your setup.

4. Hit the Ball in Front

Striking the ball in front of your body allows you to keep your head steady and limits the need for last-second adjustments, reducing the likelihood of late hits—especially on your non-dominant side. Lefties, for example, often struggle with weaker backhands for this very reason.

These foundational tips are your “Ball Watching 101.” Start incorporating them to play more consistently and with greater control.

Game Changers: How Court Surfaces Impact Your Playing Style

One of the Men’s Championship finalists commented that the synthetic grass courts at Manly felt tougher to play on compared to hard courts.
Ever wonder why your game feels effortless on some courts but a bit off on others? The surface underfoot can make all the difference! Here’s a quick guide to how synthetic grass, hard, and clay courts each influence your game—and some strategies to help you adapt and compete on each one.

🟢 Synthetic Grass Courts: Fast & Lower Bounce

Synthetic grass courts are fast and often have a low, skidding bounce, similar to natural grass. This surface favors aggressive play, allowing for shorter points and quick-fire exchanges.
  • Best Playing Style: Serve-and-volley players and net rushers dominate here. The low bounce lets you take control early and rush the net, keeping your opponent on the defensive.
  • Key Strategies: Focus on flat, low shots to keep rallies short. Be ready to take time away from your opponent by closing in on the net and using quick reflexes.
Strategy: Precision on serves and returns is key on synthetic grass. Try hitting low, slicing serves to force weak returns. This surface rewards a “first-strike” mindset—so go for it!

🔵 Hard Courts: Balanced & Predictable

The most common court type, hard courts offer a balanced mix of speed and bounce, making them ideal for players with all-court versatility.
  • Best Playing Style: Hard courts are friendly to all styles—from aggressive baseliners to serve-and-volley players.
  • Key Strategies: Use a combination of power, consistency, and variety. Adapt to your opponent by switching between offense and defense, exploiting the predictable bounce for solid baseline play.
Strategy: Footwork is critical. Rely on controlled, precise movements and adjust quickly to maintain your position. Hard courts reward versatile play, so be ready to switch tactics mid-point.

🟤 Clay Courts: Slow & High Bounce

The slowest surface with a high bounce, clay courts reward patience, endurance, and a tactical approach to point construction.
  • Best Playing Style: Baseline players and counter-punchers thrive here. Heavy topspin and strong defense are crucial to outlasting opponents.
  • Key Strategies: Master topspin shots to control the rally, and use drop shots and lobs to keep your opponent moving and off balance. Sliding is essential to cover the court efficiently and conserve energy.
Strategy: Build points with patience. Use high topspin to push your opponent deep, creating opportunities to attack when they’re out of position. Clay demands endurance, so be prepared for longer, more tactical rallies.
Each surface requires unique skills and adjustments to excel, shaping how you move, strike, and strategize. By adapting your game to the surface, you can boost your performance and embrace the nuances of each court. Whether you’re sliding on clay, powering through on hard, or attacking on synthetic grass, learning to adapt is the key to mastering any surface! 🎾💥
**Note**: Even within the broad categories of synthetic grass, hard courts, and clay, there can be substantial variations in how each surface plays. For instance, the amount of sand used on synthetic grass courts affects speed—more sand generally slows down the play. Hard courts also differ significantly based on the type of coating applied and even the court’s orientation. Courts laid lengthwise versus crosswise can impact speed and ball response, creating unique playing experiences.
The key question is: how can you adapt your game to different surfaces? That’s a topic for another post!

The Nadal Variation

You often talk about the Nadal Variation. What do you mean?
The Nadal Variation is a strategy where Nadal ran around his backhand to hit a powerful forehand cross-court shot.
This strategy allowed Nadal to:
1. Dictate Play with His Forehand: Nadal’s forehand was one of his most lethal weapons, particularly with the heavy topspin he generated. Running around his backhand let him use his dominant stroke to control the rally.
2. Exploit the Opponent’s Weaker Side: By hitting a wide cross-court forehand, Nadal pulled his opponent off the court, often targeting their backhand side, which is typically weaker for most players.
3. Create Space for the Next Shot: By pushing his opponent wide with the cross-court forehand, Nadal opened up the court, allowing him to either attack down the line on the next shot or hit an inside-out forehand to maintain control.
4. Psychological Pressure: This move was a classic Nadal tactic, imposing psychological pressure. Opponents knew that even when they target his backhand side, he could turn it into an offensive play with his forehand, making it difficult to find a safe target.

Championship Excellence Manly Lawn Club Finals 2024: A Showcase of Strategy and Tenacity

The intensity and drama of finals tennis was on full display during the Manly Lawn Club Championships 2024! By Sunday afternoon, we had crowned some new champions: Andre in Singles, Ollie in Men’s Doubles, and Xander in Mixed Doubles. Luckily, the weather held up beautifully.

Finals Results:
– Singles: Andre defeated Rimmo, 6-4, 6-4.
– Women’s Singles: Ruby edged out Carolina in a thrilling 6-4, 2-6, 6-0.
– Men’s Doubles: Sean and Ollie triumphed over Sven and Andre, 6-3, 7-6.
– Mixed Doubles: Bryanne and Xander bested Lisa and Todd, 6-2, 6-1.

Congratulations to all players on a fantastic finals weekend!

The Women’s Singles final showcased a captivating contrast of styles: Ruby’s powerful windscreen wiper forehands against Carolina’s controlled slice backhands. For two sets, it was youth versus experience in a match of tactics and endurance. Carolina’s remarkable grit and strategic attempts to outplay Ruby’s Western grip style kept us on the edge of their seats, but ultimately, Ruby prevailed as Carolina began to feel the effects of the heat in the third set.

In the Men’s Singles, Andre faced a few hiccups in his opening serve game and in closing out the first set, but he quickly took command. Rimmo put up a valiant fight, holding off numerous break points, but Andre’s relentless pressure eventually took its toll. Andre, the “Big Dog” of the tournament, brought power and a dominant presence that kept opponents on the defensive. While Rimmo tried to turn it into a running game, aiming for a backhand-to-backhand battle, Andre’s compact, well-timed backhand, along with his incredible footwork for a big man, held firm. Andre ultimately had all the answers — on the day. His powerful serve was the deciding factor, as many struggled to play him aggressively. Here’s a helpful link on strategies to tackle a huge server, which could come in handy next time!

The Men’s Doubles final saw the experienced duo of Sean and Ollie come out on top against a scratch pair, Sven and Andre. Sean and Ollie’s classic doubles play, complete with strategic signaling, proved too solid for the scratch pair, although Andre made some impressive crossing volleys. Sean, our Badge 1/1 captain, was exceptional with his reliable returns and is a terrific role model for our younger players, consistently demonstrating great sportsmanship and on-court presence. Despite a brief stumble in the second-set tiebreaker, Ollie closed the match with style, a masterclass in serving under pressure.

And finally, in the Mixed Doubles, Bryanne and Xander overpowered Todd and Lisa. It was unfortunate that Lisa had a wrist injury and couldn’t bring her best game to the court that day. Even so, what really stood out was Bryanne’s undeniable fire in the belly. She’s still got that competitive spark! Maybe it’s the joy of being out there guiding her son, Xander. I like to call her “Momma Bear” because she’s a fierce competitor and such a fantastic role model for our younger players. And ladies, take note—she’s got some serious volley skills!

As they say, tennis was the winner!

Best Volley Targets in Doubles for Winning Points

Using High-Percentage Spots to Win More Points.

In doubles, where you place your volleys can make all the difference in controlling the point and ultimately winning it.
Here are the four primary targets for volleys, each with its own high-percentage play to maximize your effectiveness at the net:

1. The Center Window (or “T” Area)

 – Why it Works: Aiming for the center window—the space between the two opposing players near the service line—is one of the highest-percentage targets in doubles. Hitting to the center reduces the angles opponents have to work with, forcing them to hit up rather than out wide.
   – When to Use: This is ideal when you’re in a stable volleying position and looking to keep the opponents on the defensive, particularly when they’re out of position.

2. Deep Cross-Court to the Baseline

   – Why it Works: A deep volley cross-court, aiming toward the baseline, forces the opponent farthest away from the net to retrieve the ball, making it harder for them to counterattack. This target also gives you and your partner more time to adjust your position and reset at the net.
   – When to Use: Use this volley target when you need to reset the rally or push the baseline player backward, taking away their time and reducing their ability to hit an aggressive shot.

3. Down the Line Near the Sideline

   – Why it Works: Going down the line can catch the net player by surprise, especially if they’re leaning towards the center to poach or cover a cross-court return. This target opens up space, as it forces one opponent to shift wide, often leaving gaps in their team’s coverage.
   – When to Use: This is effective if you notice the net player poaching or when you want to create movement and disrupt your opponents’ positioning.

4. Short, Angled Volley in the Service Box

   – Why it Works: A sharp-angled volley into the service box can exploit open spaces and make it difficult for opponents to retrieve the ball, especially if they’re positioned deep in the court. This shot takes time away from the opponent and requires them to cover a lot of ground quickly.
   – When to Use: This is best used when you’re close to the net and can control the angle effectively, or when you notice your opponents standing deep. It’s also effective as a finishing shot when you want to end the point outright.

How to Choose Your Target

Choosing the right volley target depends on several factors: your positioning, your opponent’s positioning, and the pace of the ball. By being aware of these four primary targets and selecting the right one based on the situation, you increase the likelihood of winning the point. Practicing these placements on the court will help you develop the precision and control needed to apply them in a match.

Mastering the Mind Games: Staying Focused Under Pressure

It’s disappointing that some coaches are encouraging players to unsettle their opponents in ways that stray from the spirit of fair play. It raises questions about the kind of values these tactics  are instilling in young players for the future.

Opponents often have subtle ways to distract you that don’t involve hitting the ball at all. Recognizing these tactics can make a big difference, helping you stay focused, resilient, and in control no matter what comes your way.

Here are some common tactics opponents may use to unsettle you and break your focus:

1. Handling Negative Comments

Some opponents will try to mess with your head by talking to you during the match, making negative comments, or praising your mistakes. They want you to overthink and lose confidence.

2. Slow Play (Stalling)

An opponent may take too long between points, adjusting their equipment, towel breaks, or walking slowly to serve. This slows down your rhythm and makes it hard to stay in your groove.

3. Speeding Up the Game

Opposite to slow play, some players rush between points, serving too quickly or hurrying you into mistakes. If you’re not ready, this tactic can make you feel pressured and lead to rushed, sloppy play.

4. Disputing Calls

Even if they’re not cheating outright, some players will argue every close call, creating tension. They want you to second-guess your own judgment, disrupting your focus on the game.

5. Body Language and Fake Confidence

Opponents might exaggerate their energy or show off overly confident body language—like fist pumps or aggressive looks—trying to intimidate you or make you feel they are unbeatable, even if they’re not.

6. Talking to the Umpire or Asking for Reviews

Constantly questioning the umpire, asking for reviews, or bringing up unnecessary issues can break the flow of the match and throw you off mentally.

7. Changing the Pace of Play

Some opponents will purposely mix up their game—playing slow and defensive, then suddenly hitting aggressive shots. This inconsistent pace can make it hard for you to find your rhythm.

8. Faking Injury or Fatigue

Some players might fake an injury or pretend to be extremely tired, only to suddenly spring back into form. They want you to let your guard down and get caught off-guard when they start playing hard again.

9. Excessive Celebrations

After winning a point, an opponent might celebrate excessively—even on minor points—to make you feel worse about your loss and break your concentration.

10. Disrespecting You or Showing Poor Sportsmanship

Some players will roll their eyes, clap sarcastically, or even avoid shaking hands properly. These small acts of disrespect are designed to irritate you and get under your skin.

11. Deliberate Noise or Distractions

Your opponent might grunt loudly, stomp their feet, or make distracting noises during your serve or rallies to break your concentration.

12. Taking Toilet Timeouts

Sometimes, players will take long medical timeouts to break your momentum. And, talk to the coach in the bathroom! Just remember only you and your opponents can hit the ball — no matter what the coach says.

13. Playing to Your Weaknesses

A smart opponent might relentlessly target your weak spots, like your backhand or net play. This can mentally drain you if you start focusing on your weaknesses rather than adjusting your strategy.

14. Crowd Manipulation

If there’s a crowd, some players may encourage their supporters to make noise, distract you between points or clap your errors. It can be hard to ignore, especially if the crowd is on their side.

15. Faking Agreement in Doubles

In doubles, an opponent might make comments about your partner, pretending to agree with them or saying things to make you doubt your teamwork.

16. Appearing Indifferent

Some players try to act like they don’t care about the outcome, which can make you feel less motivated. They’ll shrug off mistakes or losses as if they don’t matter, trying to make you question why you’re trying so hard.

17. Physical Intimidation

While tennis is non-contact, some players will use their body language or stand very close to you when at the net to intimidate you, making you feel uncomfortable.

18. Feigning Disinterest

An opponent might intentionally play at a lower level during practice or warm-up to make you underestimate them once the match starts. When they switch gears, you may feel caught off-guard.

19. Taking Medical Timeouts

Sometimes, players will take long medical timeouts to break your momentum. While some injuries are real, others can be exaggerated or faked to disrupt your rhythm and focus.

Recognizing these tactics is the first step to staying mentally tough and prepared for anything an opponent throws at you.

Embrace the fact that your opponent seems to believe they can’t beat you through skill alone!

Stick to your game plan, stay composed, and remember that mind games are only effective if you let them get into your head!

Success Starts in the Mind: Don’t Get Beaten Without a Racket

Handling disruptive tactics requires mental strength, focus, and preparation.

Here’s a general approach to deal with opponents trying to throw you off your game and beat you without using a racket:

1. Stay Focused on What You Can Control

You can’t control your opponent’s behavior, but you can control your reactions. When they try to distract you, remind yourself to focus on your own game—your footwork, your next shot, or your strategy. Ignore everything else.

2. Stick to Your Routine

Having a solid between-points routine helps block out distractions. Whether it’s bouncing the ball a certain number of times before serving, adjusting your strings, or taking a deep breath, this keeps you grounded and focused on the next point.

3. Don’t Engage in Their Drama

Whether it’s arguing, celebrating excessively, or making comments, don’t get pulled into their game. Stay calm and avoid talking back or showing frustration. The more you stay composed, the less power they have over you.

4. Use Mental Reset Techniques

If you feel yourself getting frustrated, take a moment to reset mentally. Deep breathing, visualizing positive outcomes, or simply pausing before your serve can help you regain focus.

5. Stay Aggressive in Your Play

Cheating, slowing down play, or distractions are easier to pull off when the points are close. Stay aggressive and play with confidence. By dominating the points, you leave less room for them to exploit you.

6. Be Prepared for Mind Games

Know that certain opponents will try these tactics, especially in competitive matches. Expect it and be ready. When it happens, you won’t be surprised, and you’ll be mentally prepared to deal with it.

7. Don’t Be Afraid to Ask for Help

If your opponent’s tactics cross the line—such as cheating or delaying too much—don’t hesitate to call for an umpire or ask a tournament official for assistance. You don’t have to handle it all alone.

When you feel frustration building, use it as fuel to play even better. Let it drive you to focus more sharply and move more aggressively. Turning frustration into positive energy can help you stay in control of the match.

In general, your opponent can only throw you off your game if you allow it. Stay mentally strong, focus on your game plan, and rise above their attempts to distract or frustrate you.

While technique and physical ability are crucial, your mental game is often what separates winners from losers, especially in high-pressure situations. At the end of the day, you’re not just battling with your opponent’s shots—you’re also battling your own mindset. Victory is often won in the mind before it’s won on the court.

Don’t let your opponent beat you without using a racket.

Mastering the Pinky Grip: Elevating Your Tennis Serve

The principle of gripping tightly with the pinkies while keeping the rest of the fingers looser, as practiced in Japanese swordsmanship, can be transferred to tennis serves in a way that significantly improves power, control, and fluidity.

In swordsmanship, the pinkies provide a stable base for control and power, while the looser grip from the other fingers allows for smooth, fluid motions. This same concept can be applied to your tennis serve, resulting in a more efficient and effective technique.

Here’s how this soft hands concept can be applied to serving:

1. Power Generation

Just like in swordsmanship, the pinky and ring fingers play a key role in generating power for your tennis serve. A firm grip with the pinkies allows you to channel strength from your arm and core into the racket, ensuring a solid transfer of energy during contact with the ball.

– How to Apply: Focus on gripping the racket tighter with your pinky and ring fingers while preparing for the serve. This grip stabilizes the racket, helping generate more power when you accelerate through the ball. This becomes particularly effective during the wind-up and contact phases of the serve.

2. Fluidity and Wrist Snap

The loose grip in the index and middle fingers promotes flexibility in the wrist, essential for generating spin and allowing the racket to move smoothly through the contact zone. A tight grip throughout all the fingers would limit wrist movement, reducing both spin and racket head speed.

– How to Apply: Keep your index and middle fingers relaxed during the serve motion, allowing your wrist to snap freely through contact. This helps generate topspin, slice, or any desired spin more effectively, while keeping your motion fluid.

3. Control and Accuracy

Gripping tightly with the pinkies while keeping the upper fingers looser provides a strong base for control while allowing for subtle adjustments in the racket’s angle. This combination ensures accuracy without the risk of over-gripping, which can lead to tension and inconsistent serves.

– How to Apply: Focus on keeping a looser grip in the upper fingers during the toss and as you bring the racket through the hitting zone. This allows for fine-tuning of the racket face, helping with better ball placement, especially in crucial moments like second serves where precision is key.

4. Serving Rhythm

A balanced grip helps promote a relaxed, natural rhythm in your serve. The firm pinky grip stabilizes the racket, while the looser upper fingers facilitate a smooth, rhythmic swing, preventing muscle tension and enabling consistent timing.

– How to Apply: Practice serving while focusing on the balance between a tight pinky grip and relaxed upper fingers. This allows you to maintain a calm, relaxed rhythm through the entire serve motion, leading to more consistent contact and timing.

5. Spin and Variations

The wrist flexibility gained from the looser grip allows players to execute a variety of serves—whether it’s adding extra topspin, slice, or kick. The relaxed grip in the upper fingers enhances your ability to control the ball’s trajectory and spin, making your serves more versatile and unpredictable.

– How to Apply: For spin serves, focus on keeping your wrist flexible by maintaining a looser grip with the upper fingers. This will help you impart more spin on the ball, allowing you to execute slice or topspin serves with ease, and make your serve harder to read for your opponent.

By incorporating the principle of gripping tightly with the pinkies while keeping the rest of the fingers loose, you can significantly improve your serve.  This soft hands grip helps generate power, enhances wrist fluidity for spin, and increases control and precision.

Applying these tips will lead to a more effective, consistent, and versatile serve, helping elevate your overall game performance.

Staying Focused During Matches

In competitive tennis matches, mental endurance is just as crucial as physical stamina.
The 20-20-20 rule, originally designed to reduce eye strain during extended screen time, can provide valuable insights into maintaining focus. The rule suggests that every 20 minutes, you take a 20-second break to look at something at least 20 feet away. This brief pause helps relax your eyes, preventing fatigue and discomfort.
Though intended for screen users, this concept can be adapted to tennis to help reset your mental focus and maintain long-term concentration. Here’s how:
Mental Breaks: Every 20 points or during changeovers (about every 20 minutes), take a deliberate mental break. Look away from the court, focusing on something distant, like a tree or the stands. This helps reset your mind and prevent mental fatigue from setting in.
Court Focus and Visualization: Use these breaks to visualize your next shots or points, which can help maintain sharpness and strategic thinking throughout the match.
Breathing Exercises: During these moments, practice deep, controlled breathing for 20 seconds. This will calm your nerves, boost focus, and clear your mind, especially during high-pressure moments.
By incorporating these mental breaks, similar to the 20-20-20 rule, you can sustain concentration and decision-making throughout long matches, keeping both your mind and body sharp.
