MONTPELLIER, France (AP) Teenager Alexander Zverev beat Michael Berrer 6-7 (2), 6-2, 7-5 in an all-German match to reach the Open Sud de France semifinals on Friday.
The 18-year-old Zverev saved 16 of 18 break-points faced, including 10 in the third set, and won on his fifth match point.
''It wasn't easy to use all the chances because of (his) great play,'' said Zverev, who beat 2014 U.S. Open Marin Cilic in the second round. ''You can have an unbelievable day like I did against Marin. You don't have those days all the time, but I got the win.''
He next plays Frenchman Paul-Henri Mathieu, who had 17 aces in a 7-6 (5), 5-7, 6-3 quarterfinal win against John Millman of Australia.
Later, top-seeded Richard Gasquet faced Marcos Baghdatis and Dustin Brown took on Ruben Bemelmans in the remaining quarters.
