Arthur Fils kept his run alive at the Masters 1000 of Cincinnati on Monday, beating Jiri Lehecka 6-1, 6-7 (7/9), 6-3 to reach the round of 16. The 21st-ranked Frenchman had to recover after dropping the second-set tiebreak, but he still found enough late to finish the job in three sets.
The result matters because Fils is not just moving on in Cincinnati; he is carrying form from a tournament that has started to look like a turning point. He reached the quarterfinals in Montréal and has now added another deep run at a Masters 1000 event, the level below the four Grand Slams that often separates promising weeks from a real climb in the ranking race.
Fils did not sound like a player who had cruised through it. “C'était l'un des matchs les plus difficiles que j'ai jamais joués! Je suis très content de mon tennis,” he said after the match, a fair read on a contest that turned after the second set slipped away. He has now won 9 deciding sets out of 9 in 2026, a streak that is hard to ignore because most ATP players do not go unbeaten that often in pressure sets across a whole season, let alone nine straight.
That is the part that gives this win weight. Fils can win fast, as he did in the first set, but he also had to survive the kind of swing that can break a match when a tiebreak goes the wrong way. Monday’s result fits a trend that has already shown up this summer, including a tense run in Montréal and the sort of stop-start weeks that can expose a player’s edge, even if the scoreboard eventually settles in his favor.
He now faces De Minaur in the round of 16, and that is where the next test begins. If Fils keeps turning tight matches into wins, the question is no longer whether he belongs in the second week of big events. It is how far that habit can carry him when the opponent on the other side is also still standing.
