MELBOURNE, Australia - Andy Murray's fourth loss in four finals at the Australian Open on Sunday still netted him a gain in the ATP computer rankings, moving him from sixth spot to fourth in the rankings list issued Monday.

Canada's Milos Raonic moved up two spots to a career-high sixth after a quarterfinal appearance in Melbourne, passing Tomas Berdych and Stan Wawrinka on the rankings list.

Australian Open champion Novak Djokovic remains No. 1, with Roger Federer at No. 2 and Rafael Nadal in third. With Murray's move to fourth, it restores the so-called "Big Four" who have dominated Grand Slams over the past decade.

U.S. Open runner-up Kei Nishikori remains No. 5 and Berdych stays seventh.

U.S. Open champion Marin Cilic, who is sidelined with a shoulder injury, is eighth, followed by 2014 Australian Open champion Wawrinka, who drops from fourth.
