Tommy Haas of Germany reached his third final of the season, rallying past Lukas Rosol of the Czech Republic 3-6, 6-4, 7-6 (0) on Saturday at the Erste Bank Open.
Haas, seeded second, won this tournament in 2001. He will play top-seeded Jo-Wilfried Tsonga or Robin Haase in Sunday's final.
The 44th-ranked Rosol hit 16 aces, raising his total for the tournament to 49. He lost just two points on serve in the opening set.
Haas couldn't convert his first break point at 3-2 but used his second to even the match. The final set went with serve before Haas dominated the tiebreaker.
Haas won his 14th career title in Munich in May. Rosol was eyeing his second career final after winning his first in Bucharest, Romania, in April.
