Sabalenka charges into Australian Open quarters, opens up on ...

Leading Australian Open contender Aryna Sabalenka has opened up about how her serving woes left her in despair before she found a solution with a biomechanist.

Now, however, the Belarusian star is surging with confidence and stands out as the player from the bottom half likely to reach the women’s final after Caroline Garcia exited Melbourne Park on Monday.

The world No.5 defeated Swiss Belinda Bencic, the Belarusian fighting to claim the first set before triumphing 7-5, 6-2 in one hour and 27 minutes.

Explaining her state of exasperation with her oft-discussed serving woes, the three-time major semi-finalist needed an expletive to explain her frustration.

Asked if she had worked with biomechanics specialists on any other of her strokes, Sabalenka said she hadn’t needed to.

“I’m super happy that it’s happened to me,” she said.

“I was, like, in that moment open for whatever.

“I was just like, ‘please, someone help me to fix this f*****g serve’. I’m sorry for swearing, but this is how it was.”

Sabalenka is brimming with confidence after getting to the final eight for the first time in Melbourne. Her tournament win in Adelaide this month came after she reached the final two at the WTA Finals in November.
