Top seed Novak Djokovic saved a match point on Sunday before defeating Sebastian Korda to win the Adelaide International and reinforce his status as a heavy title favourite for the Australian Open. 

The 21-time Grand Slam winner needed more than three hours to stamp his authority on his unseeded American opponent, son of former World No.2 Petr Korda, 6-7 (8/10), 7-6 (7/3), 6-4.
