Jannik Sinner defeated Jan-Lennard Struff in straight sets at Wimbledon to advance to the semifinals. The match featured an unusual moment when a ball fell from Struff's pocket during a rally, prompting a let call from the umpire.
Sinner, the top seed, cruised to victory on Court 1. The Italian secured his place in the SW19 semifinals with a straightforward performance against the German opponent.
The contest took a strange turn early in the second set. A spare ball slipped from Struff's pocket mid-rally on a break point, leading the umpire to award a let and replay the point.
BBC commentator John McEnroe suggested future use of video replay to check for deliberate actions. He noted the rule typically applies on a second occurrence, though no intent was found here.
Struff used the let to save the break point and hold serve. A similar hindrance incident occurred earlier this season involving Flavio Cobolli at the United Cup.
