Eighth seed Bernard Tomic came up an opening-round loser Monday at the $435,000 Swiss Open Gstaad.

France's Benoit Paire upended the Aussie Tomic 6-0, 6-4 on the clay courts at Credit Agricole Swiss Arena.

Another Frenchman landed in the second round, as oft-injured 2007 Gstaad titlist Paul-Henri Mathieu handled Russian veteran Igor Andreev, 6-3, 7-6 (7-4). Andreev was the runner-up at this Swiss event in 2004 and 2008.

Other Day-1 action saw Austrian qualifier Martin Fischer douse Swiss wild card Sandro Ehrat 6-2, 6-4 and Czech Jan Hernych sneak past Italian fellow qualifier Matteo Viola 6-3, 2-6, 6-3.

The top seeds here are last week's Stuttgart titlist Janko Tipsarevic and last week's Umag runner-up Marcel Granollers, who is the reigning Gstaad champ. Granollers beat Fernando Verdasco in last year's all-Spanish finale here.

Tipsarevic will open his Gstaad stay against Fischer.

This week's champion will collect $79,000.
