Andrea Petkovic reached her second final of the season by beating Grace Min of the United States 4-6, 6-2, 6-4 at the Gastein Ladies tournament on Saturday.

The 20th-ranked German, who won her third career title in Charleston in April, will play either the second-seeded Sara Errani of Italy or American qualifier Shelby Rogers in Sunday's final.

Petkovic, who won the event in 2009, broke Min at 3-3 in the final set and missed one match point on the American's serve before closing out the match in the next game.

Rain interrupted play for 1 ½ hours after the opening game of the final set.

The 138th-ranked Min had never been beyond the second round of a WTA event before.
