Andy Roddick defeated fellow American Sam Querrey 7-5, 7-6 (6) while Roger Federer cruised into the quarterfinals at the Swiss Indoors on Wednesday.
The fourth-seeded Roddick had 16 aces and dropped just six first-service points against the 22nd-ranked Querrey, who served 13 aces. Roddick faces Andrey Golubev in the second round.
Roddick has returned to Basel after seven years in hopes of claiming one of the last three berths in the eight-man ATP World Tour Finals in London this month. Roddick was eighth in the standings coming into the tournament.
Federer, the No. 1 seed, eased past Serbia's Janko Tipsarevic, requiring a single break in each set to complete a 6-3, 6-4 win in St. Jakobshalle.
Federer served even more efficiently than Roddick, conceding seven points in nine service games. He sealed the first set with an ace and clinched the match with a service winner.
The hometown favorite and FC Basel fan had his second-round match scheduled earlier in the evening to avoid clashing with the team's Champions League fixture against AS Roma being played across the street at the St. Jakob Park stadium.
Ninety minutes after leaving the court, Federer was seated alongside his parents at the soccer game as his Wimbledon conqueror Tomas Berdych was eliminated. The No. 3 seed slumped to a 6-4, 6-1 loss to 72nd-ranked Tobias Kamke, who made the main draw as lucky loser in qualifying.
Eighth-seeded American John Isner paid for squandering all eight of his break chances, losing 6-2, 6-7 (5), 7-5 to Dutchman Robin Haase.
In other first-round matches, France's Paul-Henri Mathieu won 6-3, 6-3 against Germany's Florian Mayer. Wild card Radek Stepanek of the Czech Republic beat Thiemo de Bakker of the Netherlands 6-3, 7-6 (5), and Finland's Jarkko Nieminen defeated Germany's Daniel Brands 6-3, 6-2 in a matchup of qualifiers.
