Rafael Nadal has continued to cut a path through the Australian Open men’s draw, scoring a straight-sets win over Argentine Federico Delbonis.

The world No.1 was taken to a second-set tiebreak but was otherwise untroubled in the 6-3 7-6 (7-5) 6-1 second-round victory on Rod Laver Arena.

“I lost a lot of opportunities on break points. Honestly, I found a way to finally win that second set and in the third, I think I played a little bit more relaxed,” he told Channel Nine.
