North Carolina: Andy Roddick rifled his ninth ace to set up a match point and finished it off with a 6-1, 6-4 win over Juan Monaco as the American continued to lift his game at the Winston-Salem Open.
Top seed Roddick is making up for a lost summer, the majority of which he sat out with a post-Wimbledon abdominal muscle strain.
"I wanted to get off in two sets, I didn't feel the heat to be honest," said Roddick of Thursday's quarter-final match. "I've been anxious and ready to play, that set the tone for the match. He has one bad service game and the thing was over."
