It wasn\u2019t to be, however, as Alcaraz got his revenge, defeating Sinner<\/a> in four sets, 6-2, 3-6, 6-1, 6-4, to secure his sixth Grand Slam.<\/p>\n Something wasn\u2019t clicking for Sinner<\/a> on Arthur Ashe Stadium in the final, as he looked a step behind Alcaraz throughout the match.<\/p>\n Providing a potential reason for Sinner\u2019s below-par performance, Nick Kyrgios\u2019<\/a> former coach has suggested the Italian may have been injured.<\/p>\n Nick Kyrgios\u2019 former coach Simon Rea had a \u2018suspicion\u2019 that Jannik Sinner was injured<\/p>\n During the latest episode of \u2018The Tennis\u2019 podcast, Kyrgios\u2019 former coach, Simon Rea, responded when asked if Sinner was \u2018carrying something\u2019 [an injury] in the US Open final.<\/p>\n \u201cIt looked like that to me,\u201d he said.<\/p>\n \u201cI\u2019m in awe of him at his best, but it just looked like he was missing a gear or a level, so that was my suspicion watching it play out in real time.<\/p>\n \u201cI was wondering if it was the stomach; it looked like it was really impeding the serve.\u201d<\/p>\n Sinner\u2019s serve fell apart in the final, and was made to look even worse by Alcaraz\u2019s excellent performance on the other side of the net.<\/p>\n PlayerAcesDouble faults1st Serve %Win % on 1st ServeWin % on 2nd ServeCarlos Alcaraz10061%83%57%Jannik Sinner2448%69%52%Serving stats from Carlos Alcaraz vs Jannik Sinner<\/p>\n Australia\u2019s Billie Jean King Cup<\/a> captain, Nicole Pratt, agreed, as she reflected on the injury time-out Sinner took in the semifinals.<\/p>\n \u201cWell, in the semifinal, he had that injury timeout, and he\u2019d just lost the set, I was thinking, this is interesting,\u201d she said.<\/p>\n \u201cThen managed to get through, but for me, there was a question mark going into the final. I wonder if he\u2019s going to be at 100% fitness; there was something just off.\u201d<\/p>\n Pratt proceeded to explain how an injury can affect a player\u2019s mentality heading into a match.<\/p>\n \u201cSometimes players, when they carry something, it carries through in their mentality, I\u2019m just not sure he was as laser-focused and dialed in as he normally is when he\u2019s playing his best,\u201d she said.<\/p>\n \u201cFor him to lose a set 6-1\u2026 something\u2019s wrong.<\/p>\n \u201cSinner was making unusual errors, like a regular forehand he\u2019s missed, not by much, but he\u2019s missed. And he doesn\u2019t normally do that.\u201d<\/p>\n The Italian hadn\u2019t lost a set 6-1 since the Italian Open<\/a> in May [vs Tommy Paul], his first tournament back after a three-month suspension.<\/p>\n![\"Carlos](\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2025\/09\/GettyImages-2234248910-1024x710.jpg\")
