Tsitsipas Upsets Fils in US Open First Round Comeback

Stefanos Tsitsipas staged a remarkable comeback to defeat 10th-seeded Arthur Fils in the first round of the US Open on Monday, August 31, 2026. The former world No. 3, now ranked 53rd and unseeded at a Grand Slam for the first time in his career, rallied from a set and a break down to win 4-6, 7-6(3), 6-1, 6-4 at Louis Armstrong Stadium. The victory was a significant upset, marking Tsitsipas's first win over a top-20 player at the US Open and his first-ever victory against Fils in six meetings. Fils, the world No. 11, had entered the tournament on a six-match winning streak after capturing his first Masters 1000 title in Cincinnati eight days earlier.
