US third seed Sam Querrey fired 11 aces in a first-round victory on Monday over Frenchman Arnaud Clement, proving a competent fill-in for Andy Roddick at the ATP Indianapolis Championships.
A 6-3, 6-4 victory in 73 minutes put Querrey alongside seventh-seeded Marc Gicquel of France and eighth-seeded Uzbek Denis Istomin in reaching the second round at the US$450,000 hardcourt tournament.
Gicquel drove another spike into the heart of a losing season for once-promising Ernests Gulbis, hammering the Latvian 6-2, 6-3, while Istomin staged a comeback to eliminate American Kevin Kim 2-6, 6-4, 6-4.
Querrey is the top-ranked American in the field after Wimbledon finalist Roddick withdrew because of the hip flexor injury that bothered him during his All-England club loss to Roger Federer a fortnight ago.
German Philipp Petzschner led the way as a group of his compatriots advanced to the second round of the German Open on Monday with the top seeds not scheduled for action until yesterday.
The world No. 49 beat Frenchman Florent Serra 7-6, 6-2 to set up a meeting with second seed Nikolay Davydenko.
German wildcard Daniel Brands, was made to work hard for a set and a half before beating Romanian Victor Crivoi 4-6, 6-4, 6-1. Brands next faces top seed Frenchman Gilles Simon.

Top-ranked Dinara Safina easily advanced to the second round of the Slovenia Open on Monday by beating Tadeja Majeric 6-0, 6-4.
Majeric, an 18-year-old Slovenian ranked No. 277, seemed nervous at the start and won just eight points during the first set while double-faulting seven times.
Also on Monday, third-seeded Kaia Kanepi of Estonia was knocked out by Olga Gotortsova of Belarus, 6-1, 6-2.
