MUNICH (AP) -- Top remaining seeds Roberto Bautista Agut and Alexander "Sascha" Zverev won on Friday and will meet in the BMW Open semifinals.
No. 2 Bautista Agut defeated German qualifier Yannick Hanfmann 6-3, 6-3, and No. 3 Zverev was made to work harder to beat fellow German Jan-Lennard Struff 3-6, 7-6 (3), 7-6 (5).
Struff ended Tommy Haas' last run at the clay-court tournament in the second round on Wednesday. The top-seeded Gael Monfils lost to Chung Hyeon of South Korea on Thursday.
Zverev, a semifinalist last year, is the last German remaining in the Munich tournament. In the other quarterfinals, Chung was playing Martin Klizan and Argentina's Guido Pella faced compatriot Horacio Zeballos.
