Florida: American qualifier Ryan Sweeting upset US third seed Sam Querrey 7-6 (7/5), 6-4 on Wednesday to reach the quarter-finals of the $442,500 ATP Delray Beach International Championships.
Sweeting won six of the last seven points, denying Querrey's fightback bid in the final game. Sweeting fell behind 0-40 but saved three break points, then rescued another with a second-serve ace before winning on his only match point.
"I feel like I'm playing good tennis," Sweeting said. "I'm one of the Americans consistently moving up, maybe not at a fast rate, but it's going in the right direction."
