The win and the method
On October 1, 2025 in Beijing, Jannik Sinner beat 19-year-old Learner Tien 6–2, 6–2 to win the China Open. It was a clinical final, not because Sinner sprayed winners from the sidelines but because he shrank the court through the middle. The match report highlights an 8.8 forehand shot-quality rating and 72-minute finish, as detailed in the ATP Beijing final match report. That is the blueprint we unpack here, and it is one you can apply in your next practice session. For context on Tien’s rise, see Learner Tien’s China Open breakthrough.
This is a story about geometry and tempo rather than fireworks. Sinner’s tactic was simple to describe and difficult to execute: hit heavy, deep balls to the center third until the rally tilted, then change direction with forehand quality. That center-first choice squeezed Tien’s angles, made the baseline feel shorter, and bought Sinner time to choose the right ball to attack.
Why the middle third matters
Think of the baseline as a three-lane highway: left lane, middle lane, right lane. If you feed balls down the middle lane with good depth, the opponent has to work around the ball to create angle. That takes time and footwork. Because the ball is coming down the center, the crosscourt window is smaller and the down-the-line option is riskier. If your shot lands deep, the bounce pushes the opponent back and the contact point drops, which further reduces the ability to change direction.
Hitting through the middle looks conservative, yet it has two hidden advantages:
- It reduces angle. From the middle, the opponent cannot create the same side-to-side stretch without overhitting.
- It raises decision pressure. When the ball is deep and central, the safest reply is another ball to the middle. That lets the player who set the pattern decide when to break it.
Sinner used both. He was not waiting. He was proactively choosing neutral-to-positive middle balls that forced Tien to lift, adjust, and eventually offer a ball Sinner could lean on.
Sinner’s three levers
1) Proactive depth through the center
Sinner’s rally ball was not a babysitter. It had shape, spin, and height that drove the bounce close to the baseline. The target was the middle stripe of the court, not the lines. By living there, he removed Tien’s favorite formation, the lefty crosscourt forehand that opens lanes. When Sinner did change direction, it was usually off a superior contact, not a guess.
Coaching translation: pick a big target that forgives small misses. Aim for the center service-line tee extended to the baseline. Add air to clear the net comfortably. If you miss by a step, you are still in the court and still in the point.
2) Forehand shot quality, not just power
Shot quality combines speed, spin, height, and depth. Sinner’s forehand rating in Beijing reflected how often his ball arrived heavy and deep, then jumped off the court at a strikeable height for him and a problematic height for Tien. That gave Sinner two options on command: hold the middle with shape or flatten and redirect into space. The first option set the table, the second cleared the plate.
Two visible patterns:
- Forehand middle to forehand middle, then forehand lift to backhand corner. This pulled Tien out of his stance without giving him a first-strike angle.
- Backhand middle counter, then inside-in forehand change when Tien’s stance opened too much to guard the deuce side.
3) Tempo control and the squeeze
Tempo is the invisible weapon. Sinner shifted rally tempo by mixing the height and heaviness of his middle balls. When he wanted time, he sent a higher, deeper arc with net clearance. When he wanted to rush Tien, he sent a flatter drive to the same central zone that reached Tien quicker and lower. Because both balls shared the same direction and target, Tien had little forewarning unless he read the strings.
The result looked like a squeeze. Tien’s contact points crept backward, his swing speed had to do more work, and his attempts to carve angle had to come from defensive positions. Sinner did not paint lines to win space. He shrank the available court first, then took the open space late.
What the numbers say
This was not only a vibe. The box score backs it up. In 72 minutes Sinner struck 24 winners against 16 unforced errors, saved both break points he faced, and won 73 percent of his points at net, per Infosys ATP Stats embedded in the ATP report. Those data points match what the eye saw. The winners tell you he finished efficiently. The unforced-error count tells you he did not pay a price for building with the middle ball. The saved break points show that even when Tien had a window, Sinner’s patterns held firm. For an additional news wrap, see the Reuters China Open final wrap.
Two more notes from the week enrich the tactical picture. Sinner arrived in the final after a physical semi yet still produced a clean, low-variance performance. And his Beijing title placed him alongside past multi-time champions at this venue. Those facts matter because they underline intent. He chose a tactic that travels under stress and on a big stage.

What you can copy today
You do not need Sinner’s pace to shrink the court. You need his choices. Here are three low-friction drills you can run this week. Coaches can scale them for juniors or adults.
Drill A: Serve plus one to the middle
Goal: Own the first two shots without flirting with the lines.
- Setup: Deuce and ad courts. Mark a rectangle that spans from the singles center line outward one racket length to either side, from baseline to two feet inside. That is your middle-third target zone.
- Reps: Twenty first serves each side, then fifteen second serves each side. After every serve, the server’s first groundstroke must land in the middle-third zone, deep enough to bounce near the last three feet of the court.
- Constraints: If the plus-one ball misses the zone, replay the serve. The point does not start until the plus-one lands in the target. If the serve misses, proceed as normal with a second serve and repeat the constraint.
- Coaching cues: On the plus-one, exaggerate hip and shoulder turn, then finish over the non-dominant shoulder for height. Pick a mid-net mini-target, not the far baseline. Let the target do the aiming.
- Scoring: One point for a serve that wins outright. Two points only if serve and plus-one both land in the zone and you win the next ball. First to twenty wins. If you are alone, use a ball machine and log your percentage. Aim for 70 percent compliance on first serves and 80 percent on seconds.
Why it works: The serve does not need to be perfect if the plus-one immediately compresses angle. You build the pattern Sinner used on nearly every point that mattered.
Drill B: Bounce–hit timing with tempo shifts
Goal: Control tempo from the center without telegraphing your intentions.
- Setup: Rally crosscourt or down the line from the middle hash mark, alternating ten-ball segments at two tempos: heavy neutral and flatter drive.
- Rhythm cue: Say “bounce” when the ball hits the court and “hit” at your contact. On heavy neutral, extend the time between bounce and hit by using a higher net clearance. On drive, reduce that time by taking the ball sooner and aiming lower over the net.
- Constraints: All balls must cross the net within the lane that starts at the center mark and extends one racket length to either side. Miss wide and the set resets.
- Coaching cues: On heavy neutral, load the legs and release upward. On drive, shorten the backswing and keep the head quiet through contact. Both balls should share the same initial aiming line to disguise intention.
- Scoring: Ten heavy, ten drive, repeat for three sets. Track how many balls you keep in the lane without sacrificing depth. Target 16 of 20 per set for advanced juniors.
Why it works: You are sending two different balls to the same target. The opponent cannot read direction, and the tempo change does the damage.
Drill C: Net-clearance targets for safe depth
Goal: Build height and depth that travel on off days.
- Setup: Place two visual targets on your side of the net. One at the tape plus 24 to 30 inches, another at the tape plus 40 to 50 inches. Use foam rings or low cones on a string tied to the fence so nothing touches the net.
- Reps: Fifteen balls in each height window, all aimed down the middle lane. Alternate forehands and backhands.
- Constraints: A ball only counts if it lands in the last four feet of the court and passes through the chosen window.
- Coaching cues: Lift with legs and torso, not the wrist. Keep the finish long and over the shoulder on heavy balls. On drive balls, think shoulder-to-shoulder finish with a firm wrist.
- Scoring: Two points per successful heavy ball, one per drive ball. Swap the values for the next set. Total after four sets decides the winner.
Why it works: You build a feel for safe height that still lands deep. The middle ball becomes a weapon instead of a placeholder.
Decision rules for match play
Patterns are easier to apply with clear rules. Borrow Sinner’s logic and translate it to your match card.
- Serve deuce side: Body serve, plus-one forehand middle. If the return is short and central, take inside-in forehand to the open deuce corner. If the return is deep, repeat middle.
- Serve ad side: Wide serve to pull, plus-one backhand middle. If the reply floats short, step around and drive inside-out forehand. If the reply is firm, go back to middle.
- Neutral rallies: Two middle balls minimum before any corner change. Break the pattern only when you see shoulder turn from your opponent that commits to one side.
- Defensive positions: Middle lift with extra height. Your only job is to reset the point.
These rules remove indecision. You are not guessing. You are waiting for a ball that deserves a change of direction.
Coaching notes on Sinner vs Tien
Tien’s lefty forehand is designed to pull a righty wide to the ad side, open the court, and then finish into the deuce corner. Sinner smothered that engine by living in the middle early in rallies. Tien had to create angle from a ball on his body, and when he tried, his error window shrank. Sinner’s forehand quality did the rest. The numbers tell the story: a clean winner-to-error balance in Sinner’s favor, two saved break points when Tien finally pried an opening, and efficient finishing at net. That is the textbook signature of a middle-third plan working under pressure.

Off-court work that supercharges the plan
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 your goal is to own the middle, train the ingredients that make it stick.
- Strength and mobility: Deep middle balls come from a strong lower body and a mobile thoracic spine. Build single-leg strength, rotational power, and ankle mobility so you can load and lift without stress.
- Vision and decision: Middle-first patterning improves when you recognize opponent cues. Run simple video sessions where players call out opponent shoulder turns in real time and decide whether to hold middle or break direction.
- Tempo control: Practice metronome rallies. Set a metronome app and sync your bounce–hit rhythm to steady beats, then shift tempo by two beats per minute up or down while holding the same target. Your body learns to speed up or slow down on command without changing direction.
Bringing it all together
Sinner’s Beijing final was a masterclass in making hard things look easy. He did not chase lines. He used the middle third to choke off angles, layered forehand quality on top to choose his moments, and controlled tempo to make good decisions look fast. The metrics align with the eye. The sequence is repeatable for juniors, pros, and club players because it relies on choices and margins rather than perfect timing.
Your next step is simple. Put the middle-first plan into your next practice. Run the serve plus one drill until your compliance climbs above 70 percent. Add the bounce–hit tempo sets. Set up net-clearance windows and demand deep landings. If you want the structure, recovery, and habit systems that make this stick, build a program around how you actually play. Then bring the Beijing blueprint to your next match and squeeze the court without taking on extra risk.
