Jannik Sinner took almost a month-long break after his incredible title triumph at Wimbledon. Talking about the reason behind this decision, he had said, “The body and mind need to recover and need to understand what happened.” Refreshed Sinner started his campaign at the Cincinnati Open, from where he left off at SW19. In his first match here, he took down Daniel Elahi Galan quite comfortably, and then in the second match, he secured yet another straight-sets victory against Gabriel Diallo. However, despite securing a victory in the R32, Sinner didn’t look pleased with his serves, and he headed straight to the practice court after the match at 10 pm and hit about 100 serves.
Sinner looks keen to defend his title in Cincy! In that match against Diallo, he hit 6 aces and committed 5 double faults, but in the very next match against Adrian Mannarino, he improved his numbers. It was 12 aces and just 2 double faults this time. After the R16 match, while sharing his thoughts about the improvement, Jannik Sinner admitted, “I felt like today I was serving very well.” Having said that, he also spoke about how challenging it is to play in Cincinnati, where weather conditions change rapidly. He was all set to face Felix Auger-Aliassime in the QF, and Sinner had a 0-2 record against the Canadian. Speaking about his upcoming challenge, Sinner said that this is going to be a “very difficult” match, but at the same time, he said he’s ready to “raise” his level of play and come up with a better result in this epic matchup.
In this QF match, Jannik Sinner took just 71 minutes to beat Felix Auger-Aliassime by 6-0,6-2. With this win, Sinner has now become the fifth male player in this century to have 25+ consecutive hard-court wins. Seeing his dominating performance in this match, the Italian was asked how working on small details in between matches helps him gain overall confidence in the rest of his game. Replying to that in his on-court interview, Sinner said, “Yeah… The first rounds are never easy because you have to get used to the conditions and situation on court. After a few matches, you know where you have to work on. It’s natural that we players feel better day after day. I’m very happy about that. Today I felt great on court. I think we saw that. But every day is gonna be different. I have to be very careful. Tomorrow is a day off. We try to have good reps in. Then we see what I can do in the semis.“

Jannik Sinner is yet to drop a set in the 2025 Cincinnati Open. He claimed his quickest win (59 minutes) of the 2025 season in the first round, and he was very close to matching that in this QF match as well. The Canadian never really looked comfortable in this duel; he committed 13 unforced errors against Sinner. With this win, Sinner will now play either Holger Rune or the ‘Giant-Slayer’ Terence Atmane (already defeated the likes of Flavio Cobolli, Joao Fonseca, and Taylor Fritz in the previous rounds) in the semis. What else did Sinner say after the match?

Jannik Sinner had previously met Felix Auger-Aliassime in the R16 of the 2022 Cincinnati Open. During that time, the Canadian had defeated him in a three-set thriller. But this time, Sinner looked well prepared! While sharing his thoughts about this match, he added, “I felt that I was returning very well today.” Sinner won 80% of points on Felix Auger-Aliassime’s second serve. “I think that was the key point, which gave me the confidence to serve well. I had a small drop in the second set when he broke me. It could have been a small change, but I am happy I broke him back quite early,” said the world number one.
Having said that, he yet again spoke about how difficult it is to face someone like Felix Auger-Aliassime. He knew it was always going to be a big challenge, facing the Canadian, so he claims that he prepared in the best way, tactically, and also admitted that he felt he was playing some great tennis in this match.
Time will tell if Jannik Sinner can retain his crown in Cincy or not, but his performance in this tournament has already drawn praise from his opponents. After his R16 match against Adrian Mannarino, the Frenchman gave an interview with L’Equipe. During that interview, he spoke about why it’s so difficult to play against someone like Sinner.
“He is in another dimension now, so clutch on every important point. He relentlessly puts you under pressure. Even when he somehow misses points, he never gives you the impression you can be in control of the match,” said Mannarino.
If Sinner manages to defend his title in Cincinnati, this will definitely boost his confidence heading into the US Open. Sinner has now secured his ninth consecutive win in Ciny! Who do you think can stop Jannik Sinner’s incredible run at the Cincinnati Open?
