STUTTGART, Germany (AP) Feliciano Lopez upset Tomas Berdych 6-7 (4), 6-3, 6-4 and Mischa Zverev ended veteran Tommy Haas' participation in the Stuttgart Open quarterfinals on Friday.
Lopez saved all nine break points he faced against the third-seeded Berdych.
Zverev defeated Haas 6-4, 6-4 for a semifinal against Lopez.
The 39-year-old Haas, who defeated Roger Federer in the second round on Wednesday, was playing for the last time at the grass-court tournament.
Zverev says, ''I'm a bit sorry, especially because I could always hear his daughter, who shouted, `Come on, Daddy!' They're special moments. He's a champion.''
Also, the fourth-seeded Lucas Pouille defeated Philipp Kohlschreiber 6-4, 2-6, 6-3.
Pouille next faces Benoit Paire or Jerzy Janowicz in the other semifinal.
