Rafael Nadal supercharged into the third round of the Australian Open in ominous form following his straight sets victory over Leonardo Mayer on Wednesday. Spain's world No.1 only dropped serve once as he reeled off a 6-3, 6-4, 7-6 (7/4) victory over the 52nd-ranked Argentine in just 2hr 38 min on Rod Laver Arena. Nadal, a losing finalist to Roger Federer last year in Melbourne, will face Bosnia-Herzegovina's 28th seed Damir Dzumhur in the third round. It was a powerful performance from the 16-time Grand Slam champion, who conceded only 10 unforced errors, stacked up against his 40 winners. Mayer played well and stuck to his guns, breaking serve for the only time in the match as Nadal was serving out to win, forcing the third set into a tiebreaker. "It was an important victory for me, he's a tough opponent," Nadal said.

The win took the 31-year-old Spaniard's Australian Open record to 53-11 as he chases his second Australian title after beating Federer in the 2009 final. Nadal, who is gunning for a 17th major title, was hampered by a knee injury at the tail-end of the 2017 season. It forced him to skip the lead-up Brisbane International this month, and he only had a one-match workout at the exhibition Kooyong Classic in Melbourne ahead of the Open.

Nadal needs to reach the quarter-finals to be certain of retaining his world number one ranking after the Australian Open, with Federer breathing down his neck.
