South African Lloyd Harris will face American Mackenzie McDonald in the third round of the Australian Open. Harris came through a tough five-setter against Australian wild card Alex Popyrin in Melbourn.

It’s the first time that Harris, currently ranked 91, has reached the third round at a Grand Slam.

MacDonald caused an upset when he beat 22nd seed Croatian Borna Coric in four sets.

Meanwhile, women’s defending champion Sofia Kenin has crashed out of the Australian Open in the second round. She was beaten by Kaia Kanepi 6-3 6-2.

Kenin hasn’t played much in the past year but admits that her biggest problem was her nerves.

This is the earliest exit of a defending Champion since Jennifer Capriati in the first round in 2003.

Kenin says she’ll have to work out how to deal with the pressure and get back to playing at a level that won her the title.

“I mean obviously, I haven’t experienced that and I obviously felt like I’m not there 100%, physically, mentally, everything my game just feels like really off. It’s not good. I mean I’m not obviously used to this, and I, right now I’ve just got to figure how to play at that level that I played at.”
