Jannik Sinner Overcomes Unusual Obstacles in Cincinnati Thriller
World No. 1 Jannik Sinner has faced plenty in his young but stellar career. But Monday night at the 2025 Cincinnati Open brought a brand-new challenge — a fire alarm mid-match.
In his third-round clash against Canada’s Gabriel Diallo, Sinner kept his cool as chaos unfolded around him. The Italian star held off the 6’8” Canadian and a second-set scare, sealing a 6-2, 7-6(6) win.
Fire Alarm Halts Play in Bizarre Scene
The drama hit in the second game of the second set. A fire alarm in the 1899 Club grandstand blared loudly, with flashing lights disrupting the match. Both players paused play for several minutes.
Officials failed to silence the alarm immediately. But instead of walking off, Sinner and Diallo agreed to continue, playing four points under flashing lights and sirens. Moments later, the alarm stopped — but the unusual incident added pressure to an already tense match.

Sinner Shows Champion’s Poise in Tie-Break Battle
Diallo refused to go down without a fight. After losing six straight games from 2-0 in the first set, the Canadian regrouped in the second. Behind a booming serve, he pushed the set to a tie-break, even holding a set point at 6-5.
But Sinner wasn’t fazed. On the biggest point of the match, he unloaded a scorching forehand return winner right at Diallo’s feet. It was vintage Sinner — aggressive, fearless, and perfectly timed.
From there, the Italian closed out the breaker 8-6.

Power Outage Delays Start of Match
Earlier in the night, fans endured another strange twist — a 75-minute delay caused by a venue-wide power outage during the previous match between Taylor Fritz and Lorenzo Sonego.
That delay pushed Sinner’s match start to nearly 10 p.m. Still, the 23-year-old remained focused. He raced through the first set, winning six straight games after falling behind 0-2.

Diallo’s Big Serve Not Enough
Gabriel Diallo, ranked World No. 35, came into the match looking to score the biggest win of his career. He fired 10 aces and held his own with powerful serving. But his inconsistency hurt him. A career-high 10 double faults and a poor second-serve percentage (just 5 of 32 points won) doomed his chances.
The Canadian played college tennis at the University of Kentucky, just two hours from Cincinnati. But even a home-region crowd couldn’t lift him past the in-form Sinner.

Sinner’s Streak on Hard Courts Grows
With the win, Sinner extended his hard-court winning streak to 23 matches. He hasn’t lost on the surface since October 2024, when he fell to Carlos Alcaraz in the Beijing final.
Even more impressively, Sinner is now 46-0 against players ranked outside the Top 20 on hard courts since losing to Dusan Lajovic in Cincinnati two years ago.

Defending Champion, World No. 1, and On a Mission
Sinner is the defending champion in Cincinnati and is playing his first tournament since winning Wimbledon 2025. Now, he’s chasing back-to-back ATP Masters 1000 titles for the first time.
At just 23 years old, Sinner already holds four Grand Slam titles. He’s been ranked No. 1 in the ATP rankings for 61 consecutive weeks, becoming the 29th man to reach the top spot.
After the win over Diallo, Sinner said:
> “It was a very difficult day at the office. He was serving very well, especially in the second set. If you don’t play well in tough situations like this, you can lose these matches.”
Who’s Next for Sinner?
Sinner will now face the winner of the match between Tommy Paul and Adrian Mannarino in the fourth round.
He’s also just 10 wins away from 300 career victories, adding yet another milestone to a remarkable 2025 season.
With a current 27-3 record this year, and already qualified for the Nitto ATP Finals in November (where he’s the defending champion), Sinner is showing no signs of slowing down.
