Former winner Nikolay Davydenko of Russia advanced to the final of the BMW Open when his semifinal opponent Radek Stepanek retired with a hamstring injury.
The seventh-seeded Davydenko, who won the Munich tournament in 2004, led 6-3, 4-0 when the Czech quit. Davydenko had treatment on his foot in the first set.
In the final, Davydenko will play fifth-seeded Florian Mayer, who beat fellow German Philipp Petzschner 6-3, 6-4.
Mayer will be seeking his first ATP Tour title and hoping to become the first German to win the BMW Open since Philipp Kohlschreiber in 2007. He is the highest-ranked German player at No. 35 and advanced to his first final of the year.
In his previous three appearances in Munich, Mayer never got past the first round.
"I think I played a nearly perfect match," Mayer said after winning against Petzschner for the third time in three matches. Both come from the southern German town of Bayreuth.
Mayer and Davydenko are 2-2 in head-to-head matches.
