Andy Murray has been left bitterly dissapointed after weeks of hard work came crashing down in his 7-6 6-3 6-7 7-6 South Africa’s Kevin Anderson in US Open fourth round.
This is the first time since 2010 that Murray has failed to reach the quarter-finals at a grand slam, while Anderson is set to make his first appearance in the last eight after seven failed attempts.
"That run is obviously something that is disappointing to lose," Murray told dailyrecord.co.uk.
"Many years of hard work have gone into building that sort of consistency and to lose that is tough.
"It was also tough to lose a match like that, over four hours, after a couple of difficult matches earlier in the tournament."
Praising the South African, the 28-year-old commended his fourth round opponent for his big serving but felt he could have done better if he had concentrated a little more.
"I was playing against an excellent player. He served extremely well. I was on the back foot quite a lot and wasn't able to play that offensively," added the 2012 US Open champion.
"I felt I was starting to put pressure on him in the second set and when I had the breakpoint at 5-3, I had a backhand pass that I really should have made.
"When you're playing against players at this level you need to make them think and give them a chance to get nervous.
“I had my opportunities but didn’t manage to capitalise on them. When you’re playing against someone as good as him, it's tough.”
Despite playing more tennis than anyone else ranked in the top 20, Murray denied that he was feeling fatigued ahead of the match and that it was won fair and square by Anderson.
"I don't think the amount of tennis I've played this year was a factor. I was able to fight as I wanted, through to the end of the match," he explained.
"It was more down to playing against Kevin on the court of that speed, and with him serving as well as he does. It was a tricky match. It comes down to a few points in each set. He managed to get them today."
