Kvitova crashes out to home heroine
Twice Wimbledon champion Petra Kvitova was sent tumbling out of the Australian Open in the second round by Daria Gavrilova, stunned 6-4 6-4 by the 21-year-old local.
The Czech sixth seed, a semi-finalist at Melbourne Park four years ago, made 35 unforced errors and was broken five times in the 89-minute contest, to the delight of the partisan crowd.
Kvitova rallied to save a match point and break back for 5-4 in the final set but Gavrilova claimed the victory when the world No 7 went long with a forehand in the next game.
Moscow-born Gavrilova, who paired up with Nick Kyrgios to win the Hopman Cup for Australia at the start of the year, will play France's Kristina Mladenovic in her first trip to the third round at a Grand Slam.
Former golden girl Eugenie Bouchard's hopes of rehabilitation in Melbourne came to a swift end as Agnieszka Radwanska sent the Canadian spinning out of the tournament with a 6-4 6-2 defeat in the second round.
