World number one Novak Djokovic hammered a misfiring Andy Murray in straight sets to win a record-equalling sixth Australian Open title and strengthen his grip on men’s tennis. The Serbian world number one swept to a 6-1, 7-5, 7-6 (7/3) victory in two hours, 53 minutes to hand Murray his fifth defeat in the Australian Open final.

Djokovic equalled the tally of Australia’s Roy Emerson, who won the tournament six times between 1961 and 1967, an achievement that has gone unmatched in the 49 years since. It was also Djokovic’s 11th Grand Slam title, and he moved into equal fifth place with Rod Laver and Bjorn Borg behind 17-time leader Roger Federer. Djokovic also extended his Grand Slam winning streak to 21 matches, and he has not lost a match at the majors since he was defeated by Stan Wawrinka in last year’s French Open final at Roland Garros.

Two-time major winner Murray, meanwhile, became only the second man to lose five finals at one major — Ivan Lendl lost five and won three U.S. Open finals in the 1980s. Djokovic had won 10 of his previous 11 matches against Murray and was 21-9 in their career meetings — including four finals at the Australian Open.
