ACAPULCO, Mexico -- Rafael Nadal needed just over an hour to beat Diego Schwartzman of Argentina 6-2, 6-2 on Tuesday to advance to the second round of the Mexican Open.
The seven-time French Open winner is making a comeback after being away from the tour for more than seven months with a left-knee injury.
Nadal made the final of the VTR Open earlier this month in Chile before losing to Argentine Horacio Zeballos. A week later he reached the final of the Brazil Open and defeated David Nalbandian to secure the title.
He is seeded No. 2 in the clay court tournament at Mexico, behind fellow Spaniard David Ferrer.
Ferrer also won his first-round match on Tuesday, defeating Antonio Veic 6-0, 6-3. Ferrer is the three-time defending champion and won last week in Buenos Aires, his second title of the season.
Nadal rested last week, giving his left knee a chance to heal. He has said the knee still hurts and has been told he has to live with it until the pain slowly goes away.
