Miami – Reigning Australian Open champion Stanislas Wawrinka downed Spain's Daniel Gimeno-Traver 6-0, 3-6, 6-3 Saturday to reach the third round of the ATP and WTA Miami Masters tournament.

The third-seeded Swiss raced through an 18-minute opening set but had to dig deeper after dropping the second set.

The newest Grand Slam champion recovered on cue in the third with an opening break to advance in just under 90 minutes, firing eight aces and broke four times.

Wawrinka owns three wins without a loss against Gimeno-Traver after defeating the number 99 twice in 2013, both times on clay.

Playing only his fourth ATP match since winning the Melbourne final over Rafael Nadal, Wawrinka improved to 14-1 on the season.

He last played the Miami hardcourt event in 2011, when he was beaten in his opening match. – Sapa-AFP
