QUÉBEC CITY, Canada - Americans continued to thrive across the border, with Christina McHale and Alexa Glatch becoming the third and fourth US players into the final eight of the Bell Challenge in Québec City, Canada.

At night, McHale and Glatch bested Québecois players, McHale beating Valérie Tétreault, 64 63, and Glatch defeating Stéphanie Dubois, 75 62.

"I knew the crowd would be behind her, but that it would be nothing against me," McHale said. "I knew she was playing well, so I just tried to play solidly and use my forehand. I just had to focus on myself and my game."

Glatch lost three games in a row from 4-2 up in the first set but regrouped well, winning the next five games in a row to lead, 75 20. She didn't let up.

"I like playing here in front of a big crowd," Glatch told reporters after the match. "The surface suits me well. Stéphanie made me work for it."

With Bethanie Mattek-Sands and Melanie Oudin making it into the quarters on Wednesday, this will be the first time in three and a half years that four Americans have made the final eight at a Sony Ericsson WTA Tour event. The last time it happened was at Memphis, also indoors, in February 2007.

Earlier in the day, No.8 seed Sofia Arvidsson and qualifier Tamira Paszek grabbed quarterfinal berths. Arvidsson, a former finalist here, recovered after blowing a 5-1 first set lead to beat Mirjana Lucic, 57 64 62, and Tamira Paszek beat Jill Craybas, conqueror of No.2 seed Aravane Rezai, 63 62.

"Jill had a good start, but I hung in there and fought for every ball," said Paszek, who lost the first three games of the match before snapping into form. "I feel healthy and I'm playing well. I really love this tournament."
