Unseeded South Korean player Hyeon Chung’s dream run at the Australian Open continues, after he ended the campaign for controversial American Tennys Sandgren in straight sets.
Chung – who caused a massive boil over when he defeated six-time Open champion Novak Djokovic in the fourth round — maintained his good form to beat Sandgren 6-4, 7-6 (7/5), 6-3 on Rod Laver Arena, ABC Online reports.
In a battle of unseeded players, Sandgren hit more aces and winners, but also committed more unforced errors, as Chung’s relentless return game got him over the line.
The American had a break in the second set and a chance to level the match at one set all, but he gave the break back for 5-4 and lost the set in a tie-break.
Chung showed some nerves when Sandgren was serving to stay in the match at 5-3 in the third set, earning three match points and losing them before finally clinching the win as the American hit a return over the baseline.
The 21-year-old from Suwon in South Korea will play the winner of Wednesday night’s match between 19-time major title winner Roger Federer and Tomas Berdych for a spot in the Australian Open final.
It’s unlikely to be the last we hear of Sandgren though, with his political alignments and social media history continuing to be a point of contention throughout his run to the last eight in Melbourne.
The man from Gallatin, Tennessee, deleted a string of old tweets after he was questioned over them ahead of his quarter-final match.
Several of the tweets argued over the “Pizzagate” conspiracy and mused over former US presidential candidate Hillary Clinton and her supposed involvement in alleged satanic rituals.
Sandgren also recently retweeted white nationalist Nicholas Fuentes and follows a host of right-wing figures on Twitter.
