World No. 2 Rafael Nadal showed no signs round match Sunday at the $4.695 million BNP Paribas Masters, the first ATP World Tour Masters event of the year.
The second-seeded Spaniard needed 75 minutes to post a 6-1, 6-3 victory over Argentina's Leonardo Mayer. Nadal didn't face a single break point in his first action since losing to Novak Djokovic in the seeming interminable Australian Open final.
Nadal has reached at least the semifinals the last six times he has participated in the tournament. The two-time winner (2007, 2009) was the runner-up to Djokovic a year ago.
Mayer is now 0-8 lifetime against top 10 players.
Up next for Nadal will be countryman Marcel Granollers. The 26th seed advanced with a 6-3, 2-6, 6-3 win over German veteran Tommy Haas.
Juan Martin del Potro beat Australian qualifier Marinko Matosevic 7-5, 6-2. The ninth-seeded Argentine will face No. 19 seed Fernando Verdasco. The Spaniard handled American Ryan Sweeting 6-2, 6-2.
Nikolay Davydenko also was a second-round winner.
The 2012 Indian Wells champion will collect $1 million.
