BASEL, Switzerland (AP) Andy Roddick has defeated fellow American Sam Querrey 7-5, 7-6 (6) to reach the second round of the Swiss Indoors event.

The fourth-seeded Roddick sent down 16 aces and dropped just six first-service points against the 22nd-ranked Querrey, who served 13 aces.

Roddick, who next faces Andrey Golubev of Kazakhstan, is hoping to keep his hold on one of the eight qualifying places for the ATP World Tour Finals in London this month.

In other first-round matches Wednesday, Radek Stepanek of the Czech Republic, France's Paul-Henri Mathieu and Jarkko Nieminen of Finland all advanced.
