MARSEILLE, France – Russian qualifier Dmitry Tursunov upset fourth-seeded Janko Tipsarevic 7-6 (4), 6-2 to reach the Open 13 quarterfinals on Thursday.
The 30-year-old Tursunov, a semifinalist at the tournament two years ago, saved the four break-points he faced and twice broke the Serb.
Sixth-seeded Gilles Simon of France advanced to his third straight quarterfinals with a 6-3, 6-1 win against Roberto Bautista-Agut, although Simon's serve was again not at its best. Although he broke his Spanish opponent seven times, he conceded three breaks of his own.
Simon faces either No. 2 Juan Martin del Potro of Argentina, the defending champion, or countryman Michael Llodra in the last eight, while Tursunov plays Gilles Muller of Luxembourg. – Sapa-AP
