MUNICH (AP) Second-seeded Gael Monfils pulled out of the BMW Open with a groin injury sustained in practice on Wednesday.
Monfils said cold weather may have been behind the injury or ''because I've played a lot recently.''
It was the third consecutive year that Monfils had to withdraw from the clay-court event because of injury. He had a bye into the second round.
The weather has been unseasonably cold this week in Munich, with rain and even snow disrupting the schedule.
Also, fifth-seeded Fabio Fognini advanced to the second round by beating Maximilian Marterer 6-3, 6-1, eight-seeded Alexander Zverev outlasted Malek Jaziri 4-6, 6-3, 6-2, and Jan-Lennard Struff eliminated seventh-seeded Vasek Pospisil 6-7 (5), 6-3, 6-2.
