WINSTON-SALEM, N.C. (AP) American John Isner made short work of his third-round match Wednesday in the Winston-Salem Open, beating Kazakhstan's Mikhail Kukushkin 6-1, 7-6 (7-3).
Isner, the tournament's top seed and two-time champion, served 17 aces and needed just 68 minutes to oust the 13th-seeded Kukushkin in the final tuneup for next week's U.S. Open.
"It could've gone a lot quicker," said Isner, who was born in nearby Greensboro, N.C. "I made it tough on myself, which I'm not too pleased about because of how I was serving. Still, I played well at the end of the match and I'm off in straight sets again, which is nice."
