WINSTON-SALEM, N.C. — Second-seeded Kevin Anderson of South Africa beat eighth-seeded Borna Coric of Croatia 6-2, 7-6 (1) on Thursday night to advance to the semifinals in the Winston-Salem Open.
Anderson, ranked 15th, will face 88th-ranked Malek Jaziri of Tunisia, a 6-3, 6-2 winner over sixth-seeded Thomaz Bellucci of Brazil.
Anderson had 10 aces Thursday in improving to 6-0 this season in quarterfinal matches, broke the 18-year-old Coric's serve twice and converted 85 percent of his first serves in winning the first set.
"I really played well today, especially in that first set," Anderson said. "It was one of those sets where everything was coming off my racket nicely, I was taking care of my service games and putting myself in each return game.
