Australian Open: Angelique Kerber ousts Maria Sharapova in straight sets

"I'm looking forward to the next challenge".

The 12-time Grand Slam champion has re-modelled his serving action to take the pressure off the joint but it held up during a four-set win over Gael Monfils in brutal heat on Thursday.

"I'm nearly dead", the tenacious Romanian said after the incredible battle, in which Davis lost a toenail and Halep served for the match four times.

Halep has been travelling under the radar somewhat at Melbourne Park as she works her way towards a maiden Grand Slam title.

Chung is through to the fourth round of a grand slam for the first time after knocking out fourth seed Alexander Zverev. "If you want to get to the top, you've got to play in all conditions", Federer said after players sweated it out searing heat.

Djokovic will now play Spain's 21st seed Albert Ramos-Vinolas on Saturday but will be delighted with the result, coming back into competitive tennis after a six month lay-off.

"Something is going on with Australia and me", said former No. 1-ranked Kerber, who the Sydney International last week for her first title since the 2016 U.S. Open.

Dark horse David Goffin's Australian Open hopes went up in smoke as he fell to a 1-6 7-6 (7-5) 6-1 7- 6 (7-4) to French veteran Julien Benneteau while Juan Martin del Potro fired 60 winners on his way to a 6-4 7-6 (7-4) 6-7 (0-7) 6-4 victory over young Russian Karen Khachanov. "But I'm here because I'm motivated to get better at my craft".

So, the final judgement following this highly anticipated match between two former Australian Open champions?

"I take pleasure out of him making that shot even though for a second I thought that this could have been the match point I had and end up losing the match". It's fine. I finished the match.

"I don't know if it will happen this year but so far, so good".

She should reach the third round for the second successive year against world No 100 Giorgi, though the Italian should be completely discounted, having beaten US Open champion Sloane Stephens earlier this month for the loss of only three games.

Praising her counterpart, she said, "Maria's a champion, she played so good the last few weeks".

"I think there are a lot of things I need to get better at and to improve on", Sharapova said.

Konta will next meet Bernarda Pera, a lucky loser in the qualifying tournament who registered the second win by an American woman at the tournament when she beat Russian qualifier Anna Blinkova 6-2, 6-2. "It was really meaningful for me to be out here".

Djokovic won their second-round match 4-6 6-3 6-1 6-3 in two hours and 45 minutes as the temperature hit 39C.

Czech Tomas Berdych, twice a semi-finalist in Melbourne, beat Spain's Guillermo Garcia-Lopez 6-3 2-6 6-2 6-3.
