Former Wimbledon champion Petra Kvitova was upset by 18-year-old

Laura Robson 6-2, 3-6, 11-9 in a second-round Australian Open match

that ended in the early hours of Friday morning.

No. 8-seeeded Kvitova was leading 3-0 in the third set before

Robson broke her three times to take a 6-5 lead. Kvitova broke back

and the set stayed on serve until Robson broke again in the 19th

game.

held at love to advance to the third round.

Kvitova, once ranked as high as No. 2, won the 2011 Wimbledon

title and reached the semifinals at the Australian and French opens

last year.
