Andy Murray of Great Britain remained perfect against Nick Kyrgios of Australia with a second round win at the 2015 U.S. Open with a score of 7-5 6-3 4-6 6-1 on Tuesday.

In the post-match interview, Murray admitted that he took advantage of Kyrgios’ lack of focus in some moments during the match.

“[Kyrgios] has an excellent serve, one of the better serves on the tour. Just sort of 5- or 10-minute periods in the match, it happens a little bit too often, where he has dips, misses a few serves, like gets distracted or loses concentration,” Murray shared via the tournament’s official website. “That's where I capitalized tonight I think.”

Murray previously beat Kyrgios in the Round of 32 of the 2015 French Open, 6-4 6-2 6-3, the quarterfinals of the 2015 Australian Open, 6-3 7-6 (5) 6-3 and the Round of 32 of the 2014 Canadian Masters, 6-2 6-2.

American John McEnroe, who worked as a commentator for ESPN, also criticized Kyrgios’ performance.

“You don’t want to be remembered as a clown. You want to be remembered as a player,” McEnroe said during the broadcast of the Murray-Kyrgios match, referring to the Australian’s antics. “I hope he learns from these bonehead moves.”

Kyrgios, who was involved in multiple controversies in recent months, admitted that having the “bad boy” image in tennis is tough.

“I thought I've been dealing with that pretty well. Obviously it's been tough. But I think I've moved on from it,” Kyrgios said after the defeat to Murray. “I thought I put in a really good performance tonight. Obviously it's not the result I wanted. But I thought I was focused and ready for today. I had a good preparation.”
