In his fourth quarterfinal of the year, Tiafoe will take on Diego Schwartzman, who outlasted Gael Monfils 7-6 (5), 4-6, 6-2.
The result denied Tsitsipas a tour-leading 15th quarterfinal of the season. Thursday's win was Tiafoe's first in seven matches against a top-three player, as Tsitsipas reached his career-high No. However, the 49th-ranked American proved his triumph at the All England Club was no fluke, as he battled back from 3-0 down in the final set to win six of the next seven games. Tiafoe upset Tsitsipas in straight sets in the opening round at Wimbledon in June, but failed to win a set when the pair met again at the Tokyo Olympics the following month.
Vienna: American qualifier Frances Tiafoe rallied to beat Stefanos Tsitsipas 3-6, 6-3, 6-4 at the Erste Bank Open on Thursday for his second win in four months over the top-seeded Greek.
