Julia Goerges upset Caroline Wozniacki for the second straight tournament Thursday, ousting the top-ranked Dane 6-4, 1-6, 6-3 in the third round of the Madrid Open.
The 27th-ranked German broke Wozniacki in the eighth game of the deciding set to lead 5-3 before serving out the match.
Goerges rallied from 3-0 down to take the first set after breaking twice. But she lost that momentum as Wozniacki leveled the match with two breaks of her own in the second set.
''The second set she started to be more aggressive and I started to get tired, so I said to myself keep yourself together for the third set and try to fight for every point,'' said Goerges, who beat Wozniacki in the Porsche Grand Prix final in Stuttgart, Germany, on April 24.
While Goerges hit 38 unforced errors to Wozniacki's 21, she also managed 36 winners to her opponent's 11 on Manolo Santana court.
''I beat her twice and twice in two weeks so I'm pretty proud of myself,'' Goerges said after taking the two-hour plus match.
Goerges plays either fifth-seeded Sam Stosur or Anastasia Pavyluchenkova in the last eight.
Bethanie Mattek-Sands secured the biggest win of her career as the 41st-ranked American knocked out the French Open champion Francesca Schiavone 7-6 (5), 6-3.
Mattek-Sands -- sporting knee-high socks and black mascara under her eyes - will play Australian Open finalist Li Na after the Chinese player rallied to defeat Roberta Vinci of Italy 2-6, 6-2, 6-1.
''I'm really happy with my play on clay right now,'' Mattek-Sands said. ''I feel like a true dirtballer.''
