Munich, Germany (SportsNetwork.com) - Rain was the big winner Friday, as all four scheduled quarterfinal matches were postponed at the BMW Open.

Top-seeded Andy Murray will face ninth-seeded Czech Lukas Rosol on Saturday.

The 27-year-old Australian Open runner-up Murray has never appeared in an ATP clay-court final.

The other quarters will pit third-seeded Spaniard Roberto Bautista Agut against Dominican Victor Estrella Burgos, fourth-seeded Belgian David Goffin versus fifth-seeded German favorite Philipp Kohlschreiber and Dominic Thiem against qualifier and fellow Austrian Gerald Melzer on the red clay at MTTC Iphitos.

Kohlschreiber titled here in 2007 and 2012 and was the Munich runner-up in 2013.

Weather permitting, the semifinals will also be staged on Saturday. Rain is in the forecast all weekend.
