Top seed Andy Roddick began his bid for a fourth San Jose Open title with a 6-0 7-6 opening-round victory over Swedish qualifier Michael Ryderstedt on Tuesday.
"It was a different match," the defending champion told reporters. "There wasn't a whole lot of rhythm to be had."
Roddick wrapped up the first set in 19 minutes, restricting
Ryderstedt to just five points.
However, the ease of winning the set made the second tough, the American world number six said.
"When he did step up his game, it was a little tough to really get into the moment again," the 26-year-old said. "I could have returned a little bit better in the second set but he was serving great."
Roddick captured 88 per cent of points on his first serve and 74 per cent on the second.
Fifth-seeded American Mardy Fish also won in straight sets, turning back Australian Lleyton Hewitt 7-6 6-3.
Eighth-seeded Robby Ginepri fell 3-6 7-6 6-4 to fellow American Todd Widom.
