Germans Tommy Haas and defending champion Philipp Kohlschreiber will play for the title at the BMW Open after winning semifinal matches on Saturday.
The third-seeded Haas rolled to a 6-4, 6-3 victory over Croatia's Ivan Dodig in the opening semifinal before the fourth-seeded Kohlschreiber rallied for a 6-7 (4-7), 6-3, 7-6 (7-5) triumph over fellow German Daniel Brands.
Haas will be vying for his 14th career ATP World Tour title and his fourth on home soil. He has won twice in Halle and once in Stuttgart, finishing as the runner-up in this event back in 2000 -- losing to Franco Squillari.
Kohlschreiber, meanwhile, will be trying for his third title in Munich. He beat Marin Cilic in last year's final after first winning this French Open tune-up in 2007.
Haas broke serve three times on Saturday, finishing off Dodig in a mere 90 minutes to reach his second final of 2013. He lost to Milos Raonic in the San Jose title match back in February and owns a career record of 13-12 in ATP finals.
Kohlschreiber battled back from a set down on Saturday, then was down a break in the third set. He eventually forced a tiebreaker and fell behind 4-1 before storming back to win in 2 hours and 14 minutes.
Sunday will mark the second final of 2013 for Kohlschreiber, who lost to David Ferrer in Auckland back in January. He is 4-4 all-time in title matches.
Haas and Kohlschreiber have split four previous meetings, all played on grass. Kohlschreiber won the most recent matchup, a five-setter last year in the first round at Wimbledon.
Sunday's winner will claim a first prize of $96,000.
