Top seed Jannik Sinner survived a spirited start from Miomir Kecmanović to win 4-6, 6-3, 6-7(6), 6-2, 6-3 in the Wimbledon Round of 128. The match on Centre Court stretched across five sets and turned on serve quality and late return pressure. Kecmanović served first and landed a few key early runs, but Sinner’s serving numbers were simply on a higher plane. By the finish, the Italian had built a 157-127 edge in total points and closed with authority on the grass.

Centre Court five-setter: score and flow

Sinner dropped the opening set 4-6 despite firing seven aces, as Kecmanović rode a nine-point run and the only break of the set. The Serb saved the big surge for set three as well, pinching the tiebreak 8-6 after staving off all five break points he faced in that set. Either side of that, Sinner controlled sets two and four with cleaner holds and constant return pressure. The decider followed that template: 6-3 Sinner, built on one break and near-flawless serving.

Across the five sets, Sinner won 28 games to Kecmanović’s 21 and posted the match’s longest streak of games at five in a row. Set durations underline the momentum swings: around 35 minutes for the opener, roughly 37 for set two, an almost 70-minute tiebreak-heavy third, then about 32 and 36 minutes to finish. Even while Sinner’s unforced errors piled up early, the match stayed tight because both protected serve for long stretches. When the top seed finally combined consistent first strikes with heavier returns, the scoreboard moved fast.

Serve supremacy: 31 aces and 89% on first balls

On grass, serve rules, and Sinner’s serve ruled this tie. He delivered 31 aces to Kecmanović’s 1 and won a huge 81 of 91 points behind his first serve, an 89% clip. He also squeezed value from the second ball, taking 26 of 47 second-serve points for 55%. Kecmanović was solid at 71% on first-serve points and 53% on second-serve points, but solid wasn’t enough against that barrage.

The split by set shows how relentless Sinner was: 7, 4, 9, 5 and 5 aces across the five sets. In set two he was untouchable on first serve, winning 16 of 16 points there; in the fifth he landed 80% first serves and won 88% of those points. Both finished with five double faults, so Sinner’s advantage came from hitting his spots, not just free points. He saved three of four break points against (75%), while Kecmanović saved five of nine (55%). By the end, Sinner had won 24 service games to Kecmanović’s 19 and logged a 107-97 edge in service points won. That platform let the world No. 1 seed play first-strike tennis without fear.

Return game tilts late

Sinner didn’t just serve better; he returned better when it mattered. He won 50 receiver points to Kecmanović’s 30 overall and converted four breaks to one. On first-serve returns he took 29 of 101 points (28%), compared to Kecmanović’s 10 of 91 (10%), a telling gap on grass. Even on second-serve returns the Italian held a slight edge, 22 of 47 (46%) to 21 of 47 (44%).

That pattern sharpened in the closing sets. In set four, Sinner won 46% of first-serve return points and 55% on second-serve return points, powering two breaks in a 6-2 frame. In the fifth, he again took 46% of first-serve return points and nicked the one break he needed. The lone wobble came in the third, when Kecmanović saved all five break points he faced and rode the tiebreak to 7-6(6). Strip out that escape, and Sinner’s pressure on return steadily rose as the match wore on. On Sofascore, the point-by-point flow makes the momentum swing easy to spot.

Shotmaking numbers tell the story

Sinner’s aggression showed up in the winner column in bold. He finished with 75 winners to 21, including 32 forehand winners and 10 on the backhand. He also owned the net exchanges, posting seven volley winners to one, plus a 2-1 edge on overheads and even a clean lob winner. Groundstroke winners were 35-18 in his favor, a sign of baseline control once rallies extended.

With that shotmaking came risk. Sinner recorded 57 unforced errors to Kecmanović’s 33, but his winners-to-unforced ratio still netted out at +18, while Kecmanović landed at -12. In the broader “Errors” grouping, Kecmanović was marked with 46 to Sinner’s 44, including the match’s only overhead error by the Serb. The takeaway is simple: Sinner’s positive plays outweighed the misses by a wide margin. On a quick Centre Court, that trade-off is usually rewarded.

Set-by-set turning points

Set one hinged on second-serve reliability. Sinner won just 2 of 9 points behind his second serve in the opener, while Kecmanović handled those exchanges better and converted his single break chance for 6-4. Set two flipped because Sinner’s first ball became untouchable: 100% of first-serve points won and the only break of the set for 6-3. That was the template he returned to later.

The third was the outlier. Sinner actually won more return points in the set (16 to 9) but could not break, as Kecmanović saved 5 of 5 break points and edged the tiebreak 8-6. From there, the top seed tightened the screws. Set four brought a clean surge: two breaks, 88% second-serve points won on his own delivery, and a 6-2 score. The fifth mirrored that control, with Sinner winning 18 service points, taking nearly half of first-serve return points, and sealing it 6-3.

This five-set win came down to first-strike tennis, backed by numbers that travel on grass: 31 aces, 89% first-serve points won, and a healthy edge in return points when it mattered most. Kecmanović produced timely streaks, especially in the opener and during the third-set tiebreak, but the weight of Sinner’s serve and forehand carried the day.
