Grigor Dimitrov caused an upset in the men’s singles category at the Australian Open 2021 on Sunday as he knocked out Dominic Thiem in straight sets at the Rod Laver Arena.
Dimitrov beat 4th seed Thiem 6-4, 6-4, 6-0 at the Rod Laver Arena in Round 4 to reach the quarter-finals.
Thiem, the U.S. Open champion, who came back from two sets down to beat Nick Kyrgios in the third round on Friday, looked out of sorts from the beginning of the contest.
The first two sets followed the same pattern with Thiem taking an early 3-1 lead only for 18th seed Dimitrov to charge back at him and clinch the set.
The Austrian, losing finalist here last year, was unable to rouse himself in the third set and Dimitrov sealed a last-eight meeting with Russian qualifier Aslan Karatsev after little more than two hours on court.
“Throughout every season you have one of those matches where you keep the ball rolling,” Dimitrov said after going 4-2 up in his career record against Thiem.
“He might have had a problem, I don’t know, but I also give myself some credit for staying in there.
“He’s an extraordinary player so I’m happy with the win.”
18th seed Dimitrov will next face 114-ranked Aslan Karatsev, who upset Felix Auger-Aliassime to become the first man since 1996 to reach the quarterfinals on his Grand Slam debut.
The 27-year-old Russian qualifier dropped the first two sets but lifted his level and cut down his error-rate to beat the 20th-seeded Auger-Aliassime in five.
