Wozniacki rolls into New Haven semis

Reigning four-time reigning champion Caroline Wozniacki was an easy quarterfinal winner Thursday at the $637,000 New Haven Open at Yale, a final U.S. Open tune-up.

The third-seeded former world No. 1 star improved to 20-0 lifetime in New Haven with a 70-minute 6-2, 6-1 dismantling of sixth-seeded Slovak Dominika Cibulkova on the hardcourts at the Connecticut Tennis Center at Yale.

The Danish star beat Czech Petra Cetkovska in last year's New Haven finale.

The 2009 U.S. Open runner-up Wozniacki's semifinal opponent on Friday will be seventh-seeded Russian Maria Kirilenko, who flattened Belarusian qualifier Olga Govortsova 6-1, 6-2 in 1 hour, 23 minutes. Kirilenko lost to world No. 1 Victoria Azarenka in the bronze-medal match at the London Olympic Games earlier this month.

The 2012 New Haven champion will collect $107,000.
