Fils in control from the outset
Arthur Fils defeated Thiago Agustín Tirante 6-3, 6-2 in the quarterfinal of the Cincinnati Open on outdoor hard courts, booking his place in the last four. For the 21st-seeded Frenchman, it was his third Masters 1000 semifinal of the season — an impressive record during the ongoing North American hard-court swing. For Tirante, it brought an end to a remarkable run of four consecutive wins in Cincinnati, which had included a stunning upset over Novak Djokovic.
The opening set was largely competitive. Neither player gained a clear edge until Fils landed the decisive break at 4-3, repeatedly driving Tirante onto the back foot with thunderous forehand groundstrokes and giving the Argentine no room to breathe. The result: a clear 6-3 first set for the Frenchman.
Tirante without an answer in the second set
Fils seized control immediately in the second set. He broke Tirante's serve early to lead 3-1 and from that point gave his opponent virtually no room to manoeuvre. Tirante was unable to apply any pressure on the Fils serve — a weakness that the numbers laid bare: Fils held every service game and did not face a single break point the entire match, simply because he never allowed one. Two further breaks sealed the 6-2 and the overall victory.
The statistics underlined the Frenchman's superiority emphatically. Fils won 79 per cent of points on his serve, claimed 83 per cent of first-serve points, and converted 60 per cent of his break points. Tirante, by contrast, won just 54 per cent of points on his own serve and failed to register a single break — his break point conversion rate stood at zero.
The end of Tirante's remarkable rise
The fact that Thiago Agustín Tirante had reached this quarterfinal at all was already a story in itself. The 25-year-old Argentine had begun the 2026 season ranked 103rd in the world and climbed to 41st in the PIF ATP Live Rankings on the back of his run in Cincinnati — a new career high. Prior to this year, Tirante had never won more than six matches at Tour level in a single season; heading into the quarterfinal, he had already recorded 26 wins in 2026.
His victory over Djokovic in the previous round — 2-6, 6-4, 6-4 after dropping the first set — had been hailed as the biggest win of his career, making him only the 14th player since 2005 to achieve that feat at Masters 1000 level. Against Fils, however, Tirante had no way of posing a genuine threat. It was the first meeting between the two players, and Fils dictated the terms of the contest from first point to last.
