MELBOURNE, Australia — Defending champion Novak Djokovic has moved into an Australian Open final against Rafael Nadal after edging Andy Murray in a five-set, almost five-hour semifinal late Friday night.

Despite appearing tired and sore from the second set, Djokovic rallied to beat Murray 6-3, 3-6, 6-7 (4), 6-1, 7-5 in a rematch of the 2011 final at Melbourne Park to reach his third consecutive Grand Slam final.

The 24-year-old Serb finished last year at No. 1 after winning three of the four majors, with his only loss at a Grand Slam coming against Roger Federer in the French Open semifinals.

He beat Nadal in six tournament finals last year.

Nadal, the 2009 Australian Open winner, beat four-time champion Federer to advance.
