Top-seeded Mona Barthel of Germany pulled out with a shoulder injury while trailing 6-2, 4-3 to the 725th-ranked Lisa-Maria Moser in the second round of the Gastein Ladies on Wednesday.
Playing in her first WTA event, Moser broke twice to take the opening set and the Austrian wild-card was a break up in the second when the 31st-ranked Barthel withdrew.
Barthel, who was looking to reach her fourth quarter-final of the season and first since winning in Paris in February, took over the top seeding after defending champion Alize Cornet of France also pulled out with a shoulder injury.
In the quarter-finals, Moser will play Andrea Hlavackova of the Czech Republic, who rallied to beat Viktorija Golubic of Switzerland 5-7, 6-1, 6-0.
Also, No. 8 seed Karin Knapp of Italy advanced to the last eight after beating Alexandra Cadantu of Romania 7-6 (7/5), 4-6, 6-1. Knapp will face second-seeded Annika Beck of Germany who defeated Mandy Minella of Luxembourg, 2-6, 6-4, 6-4 yesterday.
In first-round play, 2007 finalist Yvonne Meusburger routed Jasmina Tinjic of Bosnia 6-0, 6-0. Coming off her second career final in Budapest at the weekend, the Austrian conceded only three points on serve, including a double fault.
Meusburger beat third seed Irina Begu of Romania yesterday 6-3, 6-3 to reach the last eight, while Arantxa Rus of the Netherlands defeated Estrella Cabeza Candela of Spain 5-7, 7-5, 6-3.
