Korean tennis star Chung Hyeon heads to Australian Open semifinals

He now faces either Roger Federer of Thomas Berdych for a place in the final.

The focus on Sandgren was back on the court on Wednesday, although Serena Williams appeared to reference the controversy when she tweeted "Turns channel" as the match began.

Sandgren was pressed on whether or not he supports posts, tweets, or Internet sites by "the alt-right".

Keys, who didn't play at Melbourne Park past year because of off-season wrist surgery, is the only American woman left in the draw.

Both times, he was beaten in the first round.

As in his fourth-round elimination of six-time champion Novak Djokovic, Chung had all the answers against world No. 97 Sandgren, returning virtually everything the battling American could throw at him. Halep, the top seed, had a marathon third-round match that ended in a 15-13 third set tiebreak after coming into the tournament sporting an ankle injury.

The second set was a different story, as the two went to a nail-biting tiebreak. "I have never played in the second week at a Grand Slam", he said.

Chung broke in the opening game of the second set with a delightful backhand across the net taking the line. Chung then forced the tiebreak, as he comfortably held his serve.

Djokovic received treatment at the end of the first set and grimaced his way through the rest of the match, and must now decide what path he wishes to take.

From there, the three points should never have been in doubt, but City contrived to allow their conservative opponents back in. Newcastle manager Rafa Benitez: "When I was talking to Mike Ashley , he told me the takeover would not go through".

Serving at 5-2 he looked set to cruise to victory but Chung tightened up in the final game, before eventually claiming victory on his sixth match point.

At the age of 21, Chung is now the youngest Grand Slam semi-finalist in eight years, and the lowest-ranked Australian Open semi-finalist in 14 years.

It is likely to be a taste of things to come, with the old guard beginning to struggle badly with injuries - Federer aside - and the grand slams reverting to 16 seeds instead of 32 from next season.

"Some things are being said about me that are untrue and not particularly fair", he told broadcaster ESPN in an interview late on Tuesday. I knew that behind the court he could probably outlast me and out-grind me, he's a heck of a player. "It's 50-50 ... I don't care".

He tried to let his tennis do the talking on Rod Laver Arena, although ultimately he was out-classed by Chung, who defeated Novak Djokovic in the fourth round and maintained his momentum. "It's impressive. I wish him all the best".
