World No. 1 Jannik Sinner saved a set point to beat Gabriel Diallo 6-2, 7-6(6) and advanced to the fourth round of the Cincinnati Open.
Play was halted in the second game of the second set in his third-round match with Gabriel Diallo when a fire alarm in the 1899 club grandstand began to sound.
After a delay of several minutes, the players agreed to play through the sound and flashes, playing four points before the alarm ended, ATP reports.
Sinner ultimately closed out the match after saving a set point with a clutch forehand service return in the tie-break.
Sinner is on a 22-match hard-court winning streak since losing to Carlos Alcaraz in the Beijing final in October. He next plays the winner of Tommy Paul and Adrian Mannarino.
The 27-year-old Fritz, who lost to Ben Shelton in straight sets in Canada last week, moved past the Italian 7-6(4), 7-5 in two hours and eight minutes, without facing a break point.
Chasing his first Masters 1000 crown of the season and second overall, the former Indian Wells champ will meet Brazilian Joao Fonseca or Frenchman Terence Atmane in the fourth round.
Fritz is the first American to be among the top four seeds in Cincinnati since Andy Roddick in 2007.
Sabalenka prevails in Cincinnati with marathon win over Raducanu
Aryna Sabalenka’s Cincinnati title defense stayed alive after a marathon win 7-6 (3), 4-6, 7-6 (5) over Emma Raducanu.
The dramatic match required three hours and nine minutes, the fourth longest of Sabalenka’s career. She improved to 11-0 in first-set tiebreaks this year.
Sabalenka finished with 46 winners — and 72 unforced errors. She will play a Round of 16 match Wednesday against Jessica Bouzas Maneiro, a 6-4, 6-1 winner over wild card Taylor Townsend.
Sabalenka has now won all three career matches against Raducanu, all in the past 18 months. She’s now won 49 matches and put in more time on court (approaching 100 hours) than any other WTA Tour player.
Raducanu opened the match by winning eight straight points. The ninth, though, was a self-inflicted double fault, and signaled a shift in momentum. Sabalenka promptly broke her to get it back on serve.
After dropping four straight games, Raducanu held serve to make it 4-3. Thirty minutes into the match, after a backhand error from Sabalenka, Raducanu leveled it at 4-all. Saving two break points, Raducanu held for a 5-4 lead, WTA reports.
