Frances Tiafoe finally got the better of Daniil Medvedev — and set up an all-American US Open quarterfinal in the process — beating the 2021 champion 7-6(1), 6-4, 7-6(6) in a wild round-of-16 thriller at Louis Armstrong Stadium on Sunday night.

It was Tiafoe's first tour-level win over Medvedev in eight career meetings, snapping a run of six straight losses to the Russian. The 11th-seeded American let a two-set cushion nearly slip away — Medvedev clawed back into both the second and third sets — but Tiafoe closed it out in a deciding tiebreak in front of a raucous home crowd, according to Deccan Chronicle's match recap.

An all-American quarterfinal

Tiafoe now advances to his fourth US Open quarterfinal in five years, where he'll face fellow American Alex Michelsen, who beat Argentina's Tomas Martin Etcheverry earlier Sunday to reach his first-ever Grand Slam quarterfinal, per the US Open's official site. It's a milestone matchup for American men's tennis, which has spent years chasing a return to the sport's top tier at its home major.

THIS IS THE PEOPLE'S COURT — FRANCES TIAFOE, ON LOUIS ARMSTRONG STADIUM

Medvedev, for his part, has now failed to advance past the round of 16 at any Grand Slam this season, a steep comedown for a player who reached the US Open final as recently as 2023. Sunday's loss extends a rough stretch for the former world No. 1 as he searches for the form that once made him one of the tour's most dangerous hard-court players.

Tiafoe called it his first win over Medvedev "in a regular match," a nod to a prior exhibition meeting between the two. He and Michelsen are set to play for a semifinal berth later this week, with both Americans hoping to ride New York crowd energy deeper into the tournament than either has managed before.
