Jannik Sinner, the defending champion, powered into the Wimbledon 2025 semifinals with a commanding straight-sets win over Jan-Lennard Struff at the All England Lawn Tennis Club in London on Tuesday, 7 July. The world No. 1 prevailed 7-5, 7-6(4), 6-3 in 2 hours 35 minutes, booking his place in the last four and keeping alive his bid for a second successive Wimbledon crown.

How the match unfolded

Struff, ranked No. 74 in the world, arrived at the quarterfinal as no ordinary opponent. The 36-year-old German — the oldest man to reach a first major quarterfinal — brought a booming serve and an aggressive net-rushing game that had already unsettled higher-ranked opponents during the fortnight.

After dropping the opening set and falling behind an early break in the second, Struff lifted his intensity, deploying his heavy forehand and well-timed approaches to the net to put Sinner under genuine pressure. The German earned a set point at 5-4, 30/40 in the second set — the closest he came to levelling the contest.

Sinner, however, demonstrated the composure that defines his game at the highest level. He escaped that danger with three consecutive big deliveries — two unreturned serves flanking an ace — and then dominated the tie-break 7-4 before closing out the third set with authority.

Sinner's composure under pressure

'The second set could have ended in a different way,' Sinner said in his on-court interview. 'Tie-breaks are always 50/50. If you are one set all or two sets up, it's a big [difference]. So in the third set, I was a little bit more relaxed, for sure.'

He added: 'His percentage of first serves dropped a little bit, which helped me feel slightly more comfortable. I'm very happy to finish in three sets, but he's a very tough player to play against. So I'm pleased.'

Barring a brief hesitant spell midway through the second set — when the afternoon heat in London appeared to slow the Italian slightly — Sinner was rarely in genuine danger. His relentless baseline consistency and outstanding serving proved the decisive factors across all three sets.

Road back from Roland Garros shock

This Wimbledon run carries added significance for Sinner. He had been riding a remarkable 30-match winning streak — a run that included completing the Career Golden Masters — before suffering a shock second-round exit to Juan Manuel Cerundolo at Roland Garros. His response at the All England Club has been emphatic, and Tuesday's win marks his 10th Grand Slam semifinal appearance.

What's next for Sinner

Sinner will face either seven-time Wimbledon champion Novak Djokovic or third seed Felix Auger-Aliassime in Friday's semifinal. A win there would put the Italian within one match of becoming the first man since Djokovic himself to win back-to-back Wimbledon titles in the modern era. All eyes now turn to Centre Court on Friday.
