BANGKOK (AP) — American Donald Young beat defending champion Guillermo Garcia-Lopez of Spain 6-1, 6-7 (0-7), 7-5 on Thursday in the second round at the Thailand Open.
The fourth-seeded Spaniard, who received a first-round bye, saw his title defense crumble after two hours and 30 minutes of a baseline battle.
Victory for the 22-year-old Young secured a place in his second ATP quarterfinals, having reached the semifinals in Washington last month.
Young next plays Go Soeda of Japan, a 6-2, 7-6 (9-7) winner over Tobias Kamke of Germany.
