Samantha Stosur reached her second final of the season after winning the last five games to beat Anna Karolina Schmiedlova of Slovakia 6-1, 7-5 at the Gastein Ladies on Saturday.
The 23rd-ranked Australian, who won her seventh career title in Strasbourg in May, will play top-seeded Sara Errani or fellow Italian Karin Knapp in Sunday's final.
The second-seeded Stosur avoided break points, and won five games in a row from 1-1 to comfortably take the opening set.
She missed four break points in the opening game of the second set and fell 5-2 behind, before winning five straight games again.
The 44th-ranked Schmiedlova, who won the title in Bucharest last week, saw her eight-match winning streak ended.
