WINSTON-SALEM, N.C. (AP) — France's Adrian Mannarino beat fourth-seeded Maxime Cressy of the United States 6-4, 7-6 (3) on Thursday to reach the Winston-Salem Open semifinals.
The unseeded Mannarino beat his third straight seeded opponent to set up a match against second-seeded Botic Van de Zandschulp of the Netherlands.
"It was a good match," Mannarino said. "Maxime is a good friend and a good player. He already beat me earlier this year and I knew it was going to be a tough match."
Mannarino previously defeated No. 9 seed Emil Ruusuvuori and No. 8 seed Albert Ramos-Vinolas.
Van de Zandschulp won two tiebreakers and had 15 aces, beating 10th-seeded Benjamin Bonzi of France 7-6 (6), 7-6 (1). Van de Zandschulp will move into the top 20 in the world rankings for the first time if he can win the tournament.
