Australian Open: Dimitrov Beats Thiem to Face Karatsev

Grigor Dimitrov defeated Sunday Dominic Thiem in the Australian Open fourth round as he dismantled the US Open champion of Austria 6-4 6-4 6-0.

"I am not a machine, and I have physical issues," Dominic Thiem said after the game.

Following Dimitrov's win, he will set up a clash against Aslan Karatsev, who stunned Felix Auger-Aliassime.

"Throughout every season you have one of those matches, you just keep the ball rolling, and today was one of those," said 18th seed Dimitrov, according to BBC.

"But the thing also is that I'm also not a machine. I mean, sometimes I would like to be, but there are bad days," the third seed said.

"I think a combination of some things, some little physical issues, plus a really bad day, plus the fact that he's a great player. So a combination of those three things and a result like that can happen."
