Two finals, two solutions
From July 13 at Wimbledon to September 7 in New York, the sport’s most instructive rivalry delivered a masterclass in tactical adaptation. In London, Jannik Sinner solved a geometry puzzle on grass and beat Carlos Alcaraz in four sets, using serve-target variety, early backhand line changes, and deep central returns to control the first two shots of each game. That blueprint earned him the trophy on Centre Court, as reported in ESPN Wimbledon final recap.
Eight weeks later inside Arthur Ashe Stadium, Alcaraz answered with a different opening book. He held serve at a rarefied clip, protected his backhand corner with first-strike forehands, and reclaimed the top ranking by beating Sinner for his second US Open title, a result confirmed by the ATP final report and rankings. Same players, similar stakes, very different leverage points.
This is not just tour gossip. For coaches, junior players, and parents, these two matches are a laboratory. The patterns scale down to club tennis if you translate the ideas into simple court geography, contact timing, and serve plus one planning. For a deeper breakdown of his serving week, see How Alcaraz held 98 of 101 and this US Open serve plus one masterclass.
What Sinner mastered on grass
1) Serve-target variety that disrupts the run-around
On grass, time is the currency. Sinner served like a pitcher who refuses to let a hitter sit on one speed. Instead of falling in love with the slice-wide pattern that most right-handers use on the deuce side, he distributed targets to three quadrants: slice wide to open space, flat up the T to rush the return, and body serves to jam the forehand take-back. The body serve mattered the most. It prevented Alcaraz from dancing around to hit forehand returns and from starting points with the shot he uses to set traps.
Mechanism: a heavy percentage of serves that enter the body reduce the server’s exposure to return winners and force short, central replies. That central ball then becomes a launch pad for Sinner’s next swing.
Practical example: imagine the add side at 30-30. The most predictable serve is a lefty-style slice out wide. Sinner went the other way, into the hip, which stopped the run-around and left him a ball on the baseline. Now the plus one decision was simple. Take the forehand early and drive it at the backhand hip or roll it heavy to the open deuce side.
2) Early backhand down-the-line to freeze the compass
Alcaraz likes to guard crosscourt with elastic speed and then spring forward for a drop shot or inside-out forehand. Sinner kept breaking that compass with early backhand line changes. He did not wait for a perfect ball. He used the first neutral backhand he could take on the rise and sent it straight down the line. The shot did two things. It made Alcaraz respect the alley and it moved him off his inside-out forehand posture. When the opponent must check both directions, his split step gets shorter and his first step slows. On grass, a delay of a tenth of a second costs the rally.
Mechanism: change the direction first, then change the pace. Sinner hit that line change firm but not reckless, often at the outside edge of the sideline to avoid overcooking it.
Practical example: a four-ball rally starting crosscourt backhands. On ball two, Sinner sends the backhand line, lands it near the corner flag, and simply holds his court. The next ball from Alcaraz arrives with less angle, which resets the exchange to neutral and denies the Spaniard an inside-out forehand from a comfortable stance.
3) Deep central returns that remove angles
Sinner’s returning was a geometry lesson. Instead of trying to punch corners on a low-skidding grass bounce, he prioritized depth through the middle third. Deep middle returns are like a traffic cop standing at the T of the baseline. They slow everything down and force the server to create the next angle from a compromised contact.
Mechanism: deep middle reduces the server’s plus one reach because the ball travels longer, kicks above hip height, and arrives without an angle to work with. Against Alcaraz, who thrives on first-ball angle and cat-and-mouse drop shots, the tactic starved him of options.
Practical example: return from a slightly inside position and drive belly-button high through the center stripe. If the reply sits, step forward and send the backhand hard at the forehand hip. If it comes deep, accept neutral and reset.
How Alcaraz flipped the script in New York
The hard court in Queens changes two constants: higher true bounce and more predictable skid. That gives the returner an extra fraction of a second and gives the server cleaner purchase on the ball. Alcaraz exploited both.
1) Elite hold efficiency
Alcaraz’s serve placement and first-ball clarity were the spine of his win. According to event data, he won 98 of 101 service games across the tournament and was broken only once in the final. That is not just good serving. It is a whole-point plan built around the first two swings. He set up patterns that made Sinner guess rather than anticipate, which is a critical difference against a returner who reads toss and shoulder lines as well as anyone.
Mechanism: Alcaraz disguised the toss better on flat up the T, then paired it with either an inside-in forehand or a backhand punch to Sinner’s body. When Sinner shaded for wide serves, Alcaraz widened the lane with a last-second shoulder turn and hit down the middle. When Sinner hugged middle, he threw the slider wide and sprinted toward the next ball.
Practical example: deuce side at 40-15. Flat serve up the T for a jammed return, forehand take at shoulder height inside the baseline, then either play the inside-in to the open ad corner or knife a short angle to pull Sinner forward.

2) First-strike forehands that protected the backhand corner
In London, Sinner’s early backhand line change pinned Alcaraz to his backhand side. In New York, Alcaraz preempted that trap by using more inside-in forehands from the ad corner. The inside-in does not swing open the court for Sinner’s favorite backhand redirect. It goes through him, often at the right hip, and keeps the exchange neutral or better for the server.
Mechanism: an inside-in forehand from just outside the sideline is a safer directional change than it looks because the net is lower in the center and you are driving along the longest diagonal of the court. With his racquet speed and balance, Alcaraz made that ball a percentage play.
Practical example: serve wide on the ad side to pull Sinner off the court, recover to the center, then take the next ball early and drive inside-in through the baseline logo. Follow forward to close with a high first volley.
3) Reclaiming the middle on return
Sinner’s deep middle returns in London were a neutralizer. Alcaraz took that same idea in New York and sent it back at the source. He stepped in on second serves, returned through the body, and forced Sinner to reveal his plus one preference. Once that preference appeared, Alcaraz ran a simple fork: if Sinner tried backhand line, Alcaraz cut the angle with an early forehand; if Sinner opted for crosscourt, Alcaraz countered with the backhand down the line to push Sinner into a defensive forehand.
Mechanism: the first neutral ball decides whether the point expands to the alleys or gets bottled up down the spine. Alcaraz kept the bottle closed until he could open it on his terms.
Practical example: stand a step inside the baseline on a predictable kicker, send the return hard body height, and recover diagonally forward to the backhand side. If the next ball floats, attack inside-in or approach and volley to the backhand corner.
4) Tempo control and forward solutions
Both finals were won by the player who stepped forward first. Alcaraz added a clean layer of forward solutions in New York. He approached behind lower, flatter forehands rather than only behind lobs of topspin. That choice reduced time for Sinner to thread passers and made the first volley routine. The net does not need magic when the approach compresses space.
Mechanism: approach off a through-the-middle ball to shorten angles. When the pass must travel down the center, you can cover with one split and a diagonal step.
Practical example: after a deep center return, take the next ball early to the middle third and close. If Sinner aims at the body, volley short to either sideline. If he floats crosscourt, punch the volley behind him.
What changed, exactly
- Serve psychology shifted. Wimbledon rewarded serves that denied the run-around on return. The US Open rewarded serves that disguised the lane and created forehands at shoulder height on ball two. The common thread is not speed. It is location first, variation second.
- The first line change moved sides. On grass, Sinner seized initiative with the backhand down the line. In New York, Alcaraz used the forehand inside-in to the same effect. Both shots tell the opponent that crosscourt autopilot is off.
- The middle of the court decided momentum. Deep central returns were defensive offense for Sinner in London and offensive defense for Alcaraz in New York. Juniors should learn that the middle is not boring. It is the switchboard. For deciding-point routines that support these choices, see the One-Point Tennis Playbook.
Three drills to make these patterns your own
These are built for good juniors and college-level sparring, but scale down with smaller targets and lighter constraints. Use cones or tape to mark zones. A tablet with a tool like SwingVision, PlaySight, or even a simple phone on a tripod will help you track.
Drill 1: Serve Target Ladder with Jam Option
Goal: build variety and deny the returner’s run-around.
Setup: four cones per box. Deuce side targets are wide corner, T stripe, inner T a step off center, and a body cone just inside the line. Same for the ad side.
Format:
- Server must hit one of each target before repeating any. After each successful hit, play the point out.
- Returner declares pre-serve which wing they will try to run around. If they run around and the server hits the body cone, server earns 2 points instead of 1.
- First to 15. Switch roles and sides every five points.
Coaching cues:
- Watch the returner’s feet, not just the toss. If they cheat, pivot to body.
- After a body serve, do not overcook the plus one. Drive at the returner’s chest or hip and recover.
Progression:
- Add a scoreboard pressure layer. At 30-30 and break points, server must call the target aloud before serving. Pressure breeds honesty in patterns.
Drill 2: Backhand Line Change on Ball Two
Goal: make the early line change a reliable neutralizer, not a bailout.
Setup: coach or sparring partner feeds a deep crosscourt backhand. Player hits crosscourt, then receives a neutral ball to take on the rise down the line. Rally continues live.
Constraints:
- The line change must land past the service line and within one racquet length of the sideline. Miss short or too central, the point ends and the feeder wins.
- Player must recover with a crossover step and reestablish a neutral position two steps inside the baseline.
Reps:
- Sets of 12. Track successful depth and recovery time between contact and split step.
Coaching cues:
- Racquet head still, shoulder turn early, contact in front of the lead knee.
- Aim window over the lowest part of the net. Do not lift to the moon. Pace beats spin on this one.
Progression:
- After a successful line change, the next ball from the opponent must go crosscourt. Player anticipates, steps forward, and takes the backhand early crosscourt again. This creates a two-shot package: line, then take time.
Drill 3: Deep Middle Return plus First Strike Fork
Goal: turn center returns into plus one offense.
Setup: server hits a realistic second serve. Returner must drive deep middle through the single-sticks. Rally plays live with a forked decision on ball two.
Fork rules:
- If the server’s plus one goes crosscourt, returner changes line early on the backhand.
- If the server’s plus one goes down the line or middle, returner steps inside and plays inside-in forehand.
Scoring:
- Returner gets 2 points if the first strike lands within two feet of the baseline. Otherwise rallies count standard. First to 12, swap roles.
Coaching cues:
- Do not aim for winners on the return. Aim for height above the net and depth through the stripe.
- After the return, recover diagonally forward, not backward. Claim space before the rally expands.
Progression:
- On every third point, the returner must serve and volley after a deep middle return of their own serve. This teaches both sides of the pattern and the value of closing the middle with your body.
Match-play cues you can carry tomorrow
- Body first, corner second. When you feel the opponent leaning, jam them before you chase lines.
- Change line early to change mindsets. Use a safe-speed line change to make your rival hesitate on their favorite pattern.
- Own the middle before you open the court. A deep central ball is a time machine. It buys your next swing.
- Inside-in is a shield. If your backhand corner is under attack, replace a risky inside-out forehand with a firm inside-in through the center lane.
- Pressure test your patterns. Call your serve target at 30-30. If you cannot say it, you probably cannot hit it.
Why this rivalry should change how you practice
At Wimbledon, Sinner did not dominate because he hit harder. He made the court feel smaller for Alcaraz. At the US Open, Alcaraz did not win because he suddenly served faster. He made his patterns simpler and his plus one clearer. Simpler patterns are easier to repeat under stress. That is the real separator at every level.
Off-court training is the most underused lever in tennis. OffCourt unlocks it with personalized physical and mental programs built from how you actually play. If you tag ten service games and discover you only hit one body serve on big points, the plan is obvious. Build shoulder strength and serve repetition around that missing target, then rehearse the body-plus-one combo without a ball first, and with consequence scoring second. The point is to turn film into constraints and constraints into habits.
A coach’s checklist for the next two weeks
- Film two matches and one serve practice. Tag serve locations, plus one direction, and whether the returner ran around.
- Add one body-serve practice set with the ladder drill every session.
- Bake in five minutes of backhand line-change reps in warm up before points.
- Play one set where all returns must land through the middle third. Keep a tally of short balls earned.
- In match play, write two cues on your dampener or wristband. Example: Body at 30-all. Inside-in to hold.
The last word
Rivalries like Sinner and Alcaraz make for great television. They are also blueprints for development. Grass taught us that serve targets, early line changes, and deep center balls can control elite offense. Hard court taught us that elite holds are built from disguise, clarity on ball two, and inside-in courage. Translate those lessons into your own constraints and you will not just copy the pros. You will understand them. Then you can win with your own script.
