Novak Djokovic won his record seventh Australian Open championship Sunday, defeating Rafael Nadal in straight sets, 6-3, 6-2, 6-3 in the tournament's men's final in Melbourne.

When it was all over, the world's No. 1 men's player fell to his knees and raised his fists in triumph.

The victory was the third consecutive Grand Slam title for Djokovic, giving the 31-year-old Serbian his 15th major trophy. He trails only Switzerland's Roger Federer, who has 20 major titles, and Span's Nadal, who has 17.

Sunday's final marked a stark contrast from when the same pair played for the Aussie title in 2012. Back then, Djokovic needed 5 hours, 53 minutes to win, according to the Associated Press. This time, the match lasted just over 2 hours.
