Andy Murray disappointed in Nick Kyrgios after his Cincinnati meltdown

Andy Murray was among those frustrated at watching Nick Kyrgios have another meltdown during his second-round loss to Karen Khachanov in Cincinnati.

Kyrgios clashed with umpire Fergus Murphy several times, also hitting a ball into the stands, walking off court to smash two racquets, unusually receiving a time violation warning, and throwing his water bottle to the ground. He then insulted the umpire and spit in his direction following his defeat.

Kyrgios has since been fined a total of $113,000, an ATP tour record.

Murray and Kyrgios are friendly, with the 24-year-old Australian watching the three-time Grand Slam champion play doubles at Montreal and attending his singles match this week against Richard Gasquet. Murray also saw Kyrgios's controversial exit at Cincinnati.

"It wasn’t good, and I felt for Fergus as he shouldn’t have to put up with that," Murray was quoted as saying by BBC Sport.

The pair spoke that evening following what had occurred. It happened just a little more than a week since Kyrgios won the ATP title at Washington, D.C., where he was more entertaining than combative.

"I chatted to him a little bit," Murray said. "It’s obviously up to him, and I think for the most part a couple of weeks ago in Washington, he did a good job of helping himself and using the crowd. But obviously this week, he went back to what he was doing before."

Murray added that he hoped Kyrgios would get himself under control, because "a week like in Washington is really good for tennis," but his Cincinnati behavior "isn’t."

Kyrgios could still receive further sanctions.
