HALLE, Germany (AP) — Philipp Kohlschreiber captured his third ATP Tour title Sunday, winning an all-German match when Philipp Petzschner retired while trailing 7-6 (5), 2-0 in the Gerry Weber Open final.
The 71st-ranked Petzschner withdrew with back pain.
Kohlschreiber was a finalist in 2008, and is the fifth German champion in Halle, following Michael Stich (1994), Nicolas Kiefer (1999), David Prinosil (2000) and Tommy Haas (2009).
Petzschner lost a highly competitive first set, receiving treatment on his back after Kohlschreiber won it on the tiebreaker. Petzschner called it quits after he was broken in his first service game.
