HALLE, Germany(AP) Qualifier Olivier Rochus rallied to defeat Benjamin Becker 6-7 (4), 6-3, 6-3 Friday to advance to the semifinals of the Gerry Weber Open.
Philipp Kohlschreiber, the runner-up last year, used 17 aces to down Andreas Beck 3-6, 6-3, 6-3.
Rochus is working his way back after shoulder surgery in October. He's played mainly challenger events since he resumed his career in February.
``I am more than delighted, it's fantastic for me,'' the 28-year-old Belgian said.
Rochus was on the verge of reaching the semifinals of the same tournament three years ago, when he had four match points against Roger Federer before losing to the eventual champion.
Federer pulled out of the tournament this year after winning the French Open on Sunday.
``That was never on my mind, I never thought about it. It was a different match today,'' said Rochus, who reached his first semifinal in more than two years.
