QUÉBEC CITY, Canada - Eight became four at the Bell Challenge on Friday, as the quarterfinals of the International-level tournament took to the indoor hardcourts of the PEPS Laval University Campus.

The first two to advance were Lucie Safarova and Julia Goerges, who made it past their underdog opponents in straight sets. No.8 seed Goerges started it all off with a 62 64 win over qualifier Lilia Osterloh, then No.4 seed Safarova stopping wildcard Bethanie Mattek-Sands, a finalist here last year, 63 64.

Safarova and Goerges will now square off in the semifinals. The two hard-hitters have never faced off before. Safarova is aiming for her seventh Sony Ericsson WTA Tour singles final (she is 4-2 in the first six). Goerges has never been to a singles final on the Tour; this is her third career semifinal, going 0-2 so far.

The other quarterfinals took place at night, starting with No.3 seed Aleksandra Wozniak's 61 61 rout of Alla Kudryavtseva and ending off with an abbreviated last quarterfinal, with No.5 seed Melinda Czink winning the first set against No.1 seed Nadia Petrova in a tie-break, 76(4), before the Russian retired due to a viral illness. Petrova was the defending champion at the tournament.

Czink has beaten Wozniak in all three of their previous meetings, but the first two came on the ITF Women's Circuit (one in 2005, one in 2007), and their only Tour meeting came earlier this year on grass in Birmingham, with the Hungarian edging the Canadian in about as tight a three-setter as you can get, 67(7) 75 75.
