BRISBANE — An emotional Andy Murray fought back tears and dedicated his victory to “a sick friend” after defeating Grigor Dimitrov in a gripping Brisbane International final Sunday. Defending champion Murray prevailed 7-6, 6-4 after weathering a storm from his 21-year-old Bulgarian opponent in the opening set. The US Open champion played a flawless tiebreaker to win it 7-0 and a clinical second set allowed him to recover a service break and complete ideal preparations for the Australian Open, which begins at Melbourne Park on Jan. 14. “I'd like to dedicate this victory to one of my best friends back home,” Murray said in his speech at the presentation. “You're going to be okay. You're going to get through.” When Murray signed a television lens after the match, he wrote “For You .....”, the third word being indecipherable. He was asked about the dedication in his post-match conference and replied: “Just a sick friend.” Murray's secrecy mirrored his comments after his matches at Wimbledon and the US Open last year when he pointed both index fingers to the sky after all of his matches.
