An ailing Novak Djokovic crashed out of the Australian Open in the fourth round as up and comer Hyeon Chung clinically took advantage of the six-time champion's elbow injury to win 7-6 (7-4) 7-5 7-6 (7-3).
Kerber recovered for a 4-6, 7-5, 6-1 win that earned her a quarterfinal spot against U.S. Open finalist Madison Keys, who beat No. 8 Caroline Garcia 6-3, 6-2. "Amazing", said Djokovic, who also had an apparent hip or groin problem, screeching at times when stretching for the ball.
"When I'm young, I'm just trying to copy Novak because he's my idol", Chung said, according to the BBC.
After two days of searing heat, temperatures are forecast to a much more manageable 26 Celsius (79 Farenheit) on day six of the opening Grand Slam of the year.
Time and again during the three hour 21 minute encounter, 14th seed Djokovic had Chung on the run but the world No. 58 displayed nearly superhuman court coverage to prevail in rallies he had no right to still be involved in.
The last time Djokovic lost in straight sets at the Australian Open was back in 2007 in the round of 16 against Roger Federer, who secured his quarterfinal place earlier in the day by defeating Hungarian Marton Fucsovics.
"I don't think I played bad".
Arsenal Consider January Move For PSG's Lucas Moura
Tottenham are interested in Paris Saint-Germain's Lucas Moura , sources close to the winger have told Sky Sports News . The Brazilian global has made just the six appearances for the Ligue 1 leaders in all competitions so far this season.
"This tournament looks like a marathon for me", Halep said in an on-court interview.
Chung started the match strong, building a 4-0 lead in the first set, but Djokovic rallied back, pushing the set into a tie break, which his rival clinched. "I was just thinking 'I'm two love up in sets so if I lose (the third) I still have two more sets".
"I felt good on court", Thiem said.
Novak Djokovic has been dumped out of the Australian Open. The last man to get this far at any major without winning a previous Grand Slam singles match was Martin Verkerk, who reached the 2003 French Open final.
"I know how well he's playing, and I was really grateful for that match we played in Auckland", Sandgren said.
Djokovic wasn't even sure until the last minute that he would be able to play at Melbourne Park, but was fit enough to beat Donald Young, Gael Monfils and No. 21 Albert Ramos-Vinolas. He will face Tomas Berdych in his quarterfinal on Wenesday, a repeat of the third-round meeting past year that saw Federer rediscover his best form after a six-month lay-off. "I think he's going to win some Slams in his career, and I think he'll be around for many years".
