GSTAAD, Switzerland — Dominik Meffert won his first ATP Tour match of the year with an upset victory over fifth-seeded Andreas Seppi of Italy at the Swiss Open today.

The 27-year-old German, whose ranking of 162 is the highest of his career, beat 27th-ranked Seppi 6-2, 5-7, 6-4 in their first-round match on the red clay of Gstaad.

Meffert had to win two qualifying matches to reach the main draw of the $625,000 event.

In the second round, Meffert will play Jeremy Chardy of France, who beat Luis Horna of Peru, 7-6 (5), 6-7 (6), 7-5.

Sixth-seeded Nicolas Kiefer of Germany eased past Italy's Gianluca Naso 6-3, 6-2.

Top-seeded Stanislas Wawrinka has a bye to the second round, where he will face Stephane Bohli. Defending champion and second-seeded Paul-Henri Mathieu will play Marin Cilic of Croatia in the second round.
