Kvitova reaches semis at Aussie Open

Wimbledon champion Petra Kvitova defeated Italian Sara Errani in the quarterfinals on Wednesday at the Australian Open.

Kvitova took down Errani 6-4, 6-4 in just under two hours to secure a spot in the semifinals.

The 21-year-old Kvitova, the No. 2 seed, rallied from a 4-1 deficit in the second set to become the first Czech woman to reach the semifinals at the Australian Open since Jana Novotna in 1991.

Kvitova beat Maria Sharapova in last year's Wimbledon finale and is also the reigning WTA Championships titlist.

The 24-year-old Errani was playing in her first-ever major quarterfinal.

Ekaterina Makarova, fresh off her huge upset of Serena Williams, is taking on fourth-seeded fellow Russian Maria Sharapova on Wednesday. The winner of that match will play Kvitova in the semis.
