WINSTON-SALEM, N.C. (AP) — Ilya Ivashka, Emil Ruusuvuori and Mikael Ymer all took down seeded opponents - including No. 1 Pablo Carreno Busta - on Thursday in the quarterfinals of the Winston-Salem Open.
Ivashka beat Carreno Busta 7-6 (2), 6-3, upending the world's 12th-ranked player. That sent the 27-year-old from Belarus into Friday's semifinals to face Russuvuori, a 22-year-old from Finland who beat 14th-seeded Richard Gasquet 7-6 (5), 6-1.
The winner of that semifinal will reach their first ATP Tour hard-court final.
Ymer followed by beating 13th-seeded Frances Tiafoe 6-7 (2), 6-2, 6-3 in the first night quarterfinal. He'll face 15th-seeded Carlos Alcaraz, who became the only seeded player to win Thursday by beating Marcos Giron 7-6 (2), 6-2 in the day's final match.
Ivashka, ranked No. 63 in the world, twice converted break-point opportunities while holding serve throughout the match against Carreno Busta, a U.S. Open semifinalist in 2017.
