Andy Murray plans to keep his temper under control after a three-set win over world number 20 Ivo Karlovic put him through to the fourth round of the Pacific Life Open in Indian Wells.
Murray edged to a 7-6 (9/7) 6-7 (3/7) 6-3 win over the 6ft 10in Croat but then admitted he had lost his cool too often during the match.
"I was disappointed with my attitude during the match, I was getting really angry and I haven't done that this year," Murray told BBC Sport.
"I was just in a bad frame of mind and you can sometimes snap out of it, but when you're playing someone who is as frustrating to play against as him, it's difficult.
"I was just happy with the way I came through in the end because I was not focusing as well as I should have been."
The 20-year-old's tactics were exemplary, making it difficult for Karlovic to employ his preferred serve-volley game as he won four of five break points.
The match was predictably short of rallies, but Murray's flair eventually enabled him to prevail to set up a last-16 meeting with Tommy Haas.
Both players held their opening service games but Murray - winner of the only previous meeting in the SAP Open final in San Jose last year - then threw in a sloppy game, handing an early first break to Karlovic when he netted a forehand.
The big-serving Croat comfortably held to open up a 3-1 lead, with Murray responding in kind in a match containing predictably short rallies.
Three blistering returns helped the Scot to break back in the sixth game before he retained his next service game to love.
Neither could force a further break as the first set went to a tie-break, with Murray squandering two set points before prevailing at the third attempt.
Karlovic retained his service before breaking Murray and raced to a 3-0 lead at the start of the second set.
Murray broke back in the ninth game and drew level at 5-5 when holding serve in the next before a second tie-break of the contest followed.
Karlovic, who was previously stranded on the baseline by Murray's groundstrokes, was able to advance to the net and took full advantage of his favoured approach, comfortably closing out the tie-break to take the match to a deciding set.
Murray bounced back in the third set, going 3-0 up with a break of Karlovic in the second game and looked set to ease to victory.
But Karlovic broke back in the seventh game before Murray responded immediately.
Two phenomenal cross-court forehands earned Murray a break point which he claimed at the first attempt to earn a chance to serve out the match.
And he advanced with ease, closing out the match with a delightful drop shot.Reuse content
