MELBOURNE (Reuters) - Former world number one Maria Sharapova suffered a shock fourth round defeat at the Australian Open on Sunday, bundled out 6-2 6-3 by bottom-wiggling German Andrea Petkovic.
Bosnian-born Petkovic celebrated reaching the last eight of a major for the first time with an on-court jig.

"I'm very superstitious and since I started doing the dance I'm playing much better, so I'll try to keep it up," added the 23-year-old, who faces China's Li Na in the quarter-finals.
Squealing mightily on every shot, 14th seed Sharapova could do little right in the first set, spraying wild shots all over Rod Laver Arena.

She fended off two match points with a pair of rocket forehand returns but Petkovic completed victory in 79 minutes with a deep serve Sharapova could only push into the net.
"It definitely wasn't there," said a rueful Sharapova, who since winning here three years ago has reached just one grand slam quarter-final.

"But there are many things that didn't work today. I didn't get my first break point until it was a set and 5-1. That's not the type of tennis I want to be playing."
