In a dramatic turn of events at the Cincinnati Open, world number one Jannik Sinner displayed remarkable composure to defeat Gabriel Diallo amidst a fire alarm disruption. The incident occurred during the second set, causing a brief pause in the match as the alarm sounded and lights flashed. Despite the unexpected interruption, both players agreed to continue, and Sinner secured his place in the fourth round with a 6-2, 7-6 (8-6) victory.

Sinner, who has already claimed the Australian Open and Wimbledon titles this year, acknowledged the challenges posed by Diallo's powerful serves. 'It was a very difficult day at the office,' Sinner remarked. 'You have to find the balance against these big servers. I struggled with that at times today.'

The match was further complicated by a 75-minute power cut earlier in the day, which disrupted the TV feed and forced the use of manual line calling. Sinner started slow, losing his opening service game, but quickly regained control with three consecutive breaks to take the first set. The second set was tightly contested, eventually going to a tie-break where Sinner's experience and poise proved decisive.

Next, Sinner faces French qualifier Adrian Mannarino as he continues to build momentum ahead of the US Open later this month. The Italian star's performance in Cincinnati is a strong indicator of his readiness for the upcoming Grand Slam, where he aims to add to his already impressive collection of titles.
