Andy Murray's bid to claim back-to-back grand slam titles ended in disappointment after the Scot was beaten in the Australian Open final by Novak Djokovic.
The first two, serve-dominated sets were decided on tie-breaks before Djokovic claimed the first break of the match late in the third.
It proved a pivotal moment with US Open champion Murray, who was struggling with blisters on his right foot and a hamstring problem, unable to mount a fightback as Djokovic cruised through the fourth to complete a 6-7 (2/7) 7-6 (7/3) 6-3 6-2 success.

His triumph handed the Serbian a place in the history books as the first man in the Open era to win three successive Melbourne crowns.
The first two sets were similar with very few opportunities offered to the receiver.
Djokovic had the better chances in the first with five break points split between the sixth and eighth games only for Murray to serve his way out of danger.
The world number one's frustration at failing to convert, coupled with irritation with his footwear, boiled over in the tie-break as his game capitulated.
It was Murray who was the aggressor in the second as he looked to double his advantage.
He had three chances to leap into a 2-0 lead but Djokovic changed tack, charging the net to escape immediate danger.
It remained on serve until another breaker which was tight until Murray threw in just his third double fault of the tournament at 2-2.
He put his first serve into the net and was shaping up to deliver the second when he noticed a feather dropping on to the court out of the corner of his eye.
Having removed it, he promptly put the second serve long.
It was all Djokovic needed to level the match and the momentum appeared to swing further in his favour when Murray had to call a medical time-out for blisters at the change of ends with television pictures showing the extent of the damage to his right foot.
There was no immediate change in his movement although there was the definite sense the match was now Djokovic's for the taking.
And the top seed needed no second invitation as he set up three break points for a 5-3 lead.
Two poor forehands saw the first two come and go but Murray could not escape a third as Djokovic claimed the first break of the match before serving it out.
Murray was clearly upset at umpire John Blom for not doing more to quieten the crowd and in particular one heckler who had forced him to halt his service action twice at important points of the third set.
Yet he started the fourth on the front foot, setting up his first break point chance since the second game of the second set only for Djokovic to close the door with a booming serve out wide.
By now, Murray was also clutching his left hamstring and it was no surprise that Djokovic broke again for 2-1, winning a long rally at 30-40 after a tired-looking Murray jammed a backhand into the net.
The match was slipping away from Murray and he dropped his serve once more on a double fault as Djokovic established a 4-1 lead.
The effort was certainly there as the world number three continued to chase down every ball despite being in obvious discomfort but there was no let-up from Djokovic as he completed his 21st consecutive win in Melbourne and gained revenge for his defeat to Murray in the US Open final last September.
Murray's previous finals
US Open, 2008: Roger Federer bt Murray 6-2 7-5 6-2
This was Murray's grand slam breakthrough as he survived a two-day, rain-affected thriller to defeat Rafael Nadal in the semi-finals. The odds were firmly against him as he returned the next day to face Federer, the four-time defending champion, and Federer's dominance at Flushing Meadows never looked in any real danger as experience won the day.
Australian Open, 2010: Federer bt Murray 6-3 6-4 7-6
It took Murray another 18 months to reach a second slam final, and again it was Federer across the other side of the net. This match was certainly closer but once more Federer proved too strong, although Murray should have extended the match at least to four sets. The loss hit the British player a lot harder than his first final loss, and he broke down in his on-court interview, saying: "I can cry like Roger, it's just a shame I can't play like him."
Australian Open, 2011: Djokovic bt Murray 6-4 6-2 6-3
Twelve months later Murray was back in the final in Melbourne, and for the first time it was not Federer he was facing. However, Djokovic was at the start of a season in which he would win three grand slam titles and establish himself as the world's best player. The Serbian was far too strong but Murray put in a poor performance and was badly affected by the loss, failing to win a match for the next two and a half months.
Wimbledon, 2012: Federer bt Murray 4-6 7-5 6-3 6-4
Murray ended a 74-year wait for British tennis by reaching the men's singles final and for the first time in a grand slam final he produced his best tennis. He won his first set and threatened to take a two-set lead but Federer turned things round and, helped by the shutting of the roof, won a seventh Wimbledon title. Murray struggled to speak through tears in his post-match interview and was loudly cheered as he said: "I'm getting closer." Four weeks later he thrashed Federer to win Olympic gold on Centre Court.
US Open, 2012: Murray bt Djokovic 7-6 7-5 2-6 3-6 6-2
Four years after he first reached a grand slam final and at his fifth attempt, Murray finally became a champion. It was fitting that it should happen in such dramatic circumstances after his tortuous journey. The Scot edged both the first two sets but Djokovic hit back to level and it seemed Murray might miss out again. But he seized his chance in the decider with Djokovic ailing physically and became Britain's first male grand slam singles champion since Fred Perry in 1936.
