Video: Ballgirl gets hit in the face at the Australian Open

For one ballgirl at the Australian open today, she got slightly too close to the action, or perhaps the action got too close to her, as a return from Florian Mayer off a David Ferrer serve struck her straight in the face.

Bar a quick reaction as she gets hit, she’s straight back to business afterwards, no messing. A quick thumbs up from Mayer, and all is right with the world again.

Ana Ivanovic dumps Serena Williams from Australian Open in the fourth round

Serbia's Ana Ivanovic stunned world number one Serena Williams at the Australian Open on Sunday with a 4-6 6-3 6-3 fourth-round upset at Rod Laver Arena.

Ivanovic ended the American's 25-match winning streak to reach her first grand slam quarter-final since the 2012 U.S. Open with an inspired display of clean hitting.

"It's amazing. I just tried to play the best I could," a thrilled Ivanovic said in a courtside interview.

"You guys have been amazing. I'm so thrilled," she told the crowd.

Ivanovic, a former world number one, had never taken a set off Williams in their four previous encounters.

A winner at Roland Garros at 2008, she was aggressive from the outset, breaking Williams at 2-2 in each of the first two sets and holding firm in the second to draw level.

A shell-shocked Williams was then broken at 1-0 in the deciding set when the Serbian laced a brilliant return down the line.

With the Rod Laver Arena crowd roaring their support for the underdog, Ivanovic coolly raised three match points and sealed the tournament's biggest upset when Williams missed a return.

Ivanovic will play the winner of Casey Dellacqua and Eugenie Bouchard for a place in the semi-finals.

"It was not easy playing such a champion and I had never beaten her before, but she is just a human and I know that she has pressure on her too," she added.

"So I just went out there and was swinging at the ball and I did that really well."

VIDEO: Serena Williams hits her own face in Australian Open victory

Serena Williams once again battled through the pain barrier to advance at the Australian Open on Thursday, but this time the American third seed's injury was entirely self-inflicted.

After rolling an ankle during her first round win the 15-time grand slam champion hit herself in the face with her racket as she brushed aside Spanish teenager Garbine Muguruza 6-2 6-0.
It left her anxiously checking her mouth for damage.
