Jannik Sinner returns to Wimbledon action against Jan-Lennard Struff, and this quarter-final has far more depth than the ranking gap suggests. Sinner has rolled through four rounds without dropping a set, while Struff has fought back from two sets down just to reach this stage.
Both men bring very different games to Centre Court, and that contrast should shape how this match plays out.

Why Does Sinner Remain the Clear Favourite?
Sinner has looked untouchable through four matches at the All England Club. He beat qualifier Shintaro Mochizuki in straight sets, winning 82% of his first serve points along the way. That win stretched his current Wimbledon streak to eleven matches without a loss.
His head-to-head record against Struff also favours him heavily. Sinner leads 3-0 overall and holds a 1-0 edge on grass after their meeting at Halle two years ago. He dropped a set that day, but still came through comfortably in the end.
Why Can Struff Push This Match Deep?
Struff arrives full of confidence after one of the best runs of his career. He beat Sebastian Baez, Brandon Nakashima and Daniil Medvedev before advancing when Hubert Hurkacz retired hurt in the fifth set. That run made him the oldest man in the Open Era to reach a first Grand Slam quarter-final.
His serve has been the key weapon throughout the tournament. On grass, that shot lets him hold serve with ease and stay competitive even against elite returners like Sinner.
Best Bet Arguments for Sinner vs Struff Over 30.5 Games
Struff does not need a shock result for this total to land, since a straightforward Sinner win in three close sets would already clear the line. Their Halle meeting backs this up too, as Struff stayed competitive throughout despite losing in three sets. His big serve should keep games on serve and push the total well past 30.
