Andy Murray admitted that “something has to change” after losing in the third round at Indian Wells to Alexander Zverev, then appeared to shout obscenities as he left the field.
The former world number one was beaten in straight sets by the Olympic gold medalist 6-4, 7-6 (4).
The German was the third seed and has played well all year, but Murray has had a lot of problems.
The Briton raced to an early break before Zverev could settle into his rhythm and narrowly win the first set.
The second set started off similarly, with Murray again taking a break before allowing Zverev to return to the game.
Murray made the most of some unusual Zverev mistakes to force a tiebreaker, but the 2020 US Open finalist was able to earn the crucial points down the stretch to advance to the fourth round.
The 34-year-old was clearly frustrated with his performance in California and walked off the pitch screaming for himself.
He then tweeted “f ***” on social media.
Murray said: “I’m not saying he played well either, but I don’t think I played well today. There were a lot of mistakes.
“There were good things in there, but they were mixed with bad things. There was no consistency I don’t think. My average level just wasn’t really there today. It was either good or bad. Yeah, I wouldn’t say it plays really well.
“The positive I get from that is that I obviously had opportunities again. Yeah, I mean, I guess that’s positive. I didn’t feel like I played a great game and still had chances, so that’s positive.
“But, yeah, I’m disappointed because, I mean, obviously I want to win these games. I haven’t in the last few months.
“Yes, something has to change. “
Murray also revealed that he plans to skip the Davis Cup finals next month because he feels unworthy of his place.
“I gave a lot to the Davis Cup, and sometimes to my own physical detriment,” he told BBC Sport.
“The same thing happened the last time I played Davis Cup at the end of 2019. I know there was coronavirus, but I really struggled with it until September of the year next.”
