Novak Djokovic has overcome an almighty scare from Alexei Popyrin and a heated confrontation with a heckler to reach the Australian Open third round and keep his bid for a record 25th slam alive.
Precocious local talent Popyrin threatened to scupper Djokovic's attempt to surpass Margaret Court when he had four set points in the third set in Wednesday's match, but the champion saved them all on his way to a 6-3 4-6 7-6 (7-4) 6-3 win.
