Munich, Germany (Sports Network) - Top-seeded Frenchman Paul-Henri Mathieu highlighted Wednesday's second-round winners at the clay-court BMW Open.

Mathieu handled Italian qualifier Gianluca Naso 6-3, 6-4 on Day 3 at MTTC Iphitos. Up next for the Frenchman will be eighth-seeded Croat Marin Cilic.

An upset came when Simone Bolelli bounced sixth-seeded fellow Italian Andreas Seppi 6-4, 7-5 at this French Open tune-up.

The aforementioned Cilic avoided an upset by holding off German Philipp Petzschner 6-4, 7-6 (9-7), while Korean Hyung-Taik Lee dropped Brazilian lucky-loser and fellow non-seed Julio Silva 6-1, 6-4. Lee will encounter Bolelli in the round of eight here.

Wild card and former world No. 1 Marat Safin was an opening-round victor, as the big Russian outlasted Argentine Carlos Berlocq 6-3, 3-6, 6-4 in a match that was postponed because of rain here on Tuesday. Safin will face German Michael Berrer on Thursday.
