MONTERREY, México - Rain pushed most of it into the night, but Quarterfinal Friday was completed at the Whirlpool Monterrey Open, with Sara Errani among the winners at the picturesque International-level tournament.

Errani, the No.2 seed, continued to blaze through the draw with a 61 62 win over Mandy Minella. After Minella held in the first game of the match Errani went on an absolute tear, winning 10 games in a row to build a 61 40 lead against the first-time WTA quarterfinalist, closing the match out four games later.

"I'm feeling very good about my game this year, and now I'm two matches away from this title," Errani said. "But everyone is tough and I'm just focusing on the semifinals tomorrow - I'm going to give everything on the court tomorrow."

Next up for Errani will be Hungarian teenager Timea Babos, who followed up her second round upset of No.3 seed Sorana Cirstea with a 64 62 quarterfinal win over Patricia Mayr-Achleitner. Having never won back-to-back WTA main draw matches beforehand, Babos is now through to her second WTA semifinal in as many weeks, having also gone this far on the clay of Bogotá last week.

The other semifinal pits No.6 seed Greta Arn against Romania's Alexandra Cadantu. Cadantu was the only one to complete her match before the rain fell, winning 10 games in a row to beat No.8 seed Lourdes Domínguez Lino, 62 60; Arn beat Nina Bratchikova, 61 76(6), but not after some late trouble - she originally led 5-2 in the second set and needed four match points to win.

Cadantu had only won one WTA main draw match before this week, and has now won three in a row to reach the first WTA semifinal of her young career.

"It was magnificent to play on center court," Cadantu said. "The score made it look easy but the points were very tough. Our rallies were long and in between points I had to stop and take some deep breaths. I had to fight a lot.

"This is my best result, but I hope it doesn't end here."

Both of Saturday's singles semifinals will be first-time meetings.

The doubles semifinals will both take place Saturday as well, including an all-star match-up between No.1 seeds Errani and Roberta Vinci and the wildcard team of Gisela Dulko and Paola Suárez. Suárez has made her comeback to the WTA doubles scene with the goal of winning an Olympic medal.
