He showed no sign of the knee problems that sidelined him at the end of last year.
Nadal said he just wanted to get off to a good start and wasn’t trying to send a message.
Nadal, who reached the semifinals last year and is seeking his sixth Grand Slam title, finished with 47 winners to seven for Rochus and also blasted 10 aces.
The 75th-ranked Belgian, managed to laugh several times because basically there was little he could do.
The match only took 77 minutes . Rochus joked that he might need to consider a change in professions.
Nadal said it’s too dangerous to show any mercy.
“Sport is like this,” Nadal said.
“If I had some mistakes … anything can happen.”
"I'm just trying to improve and to be humble because every match is different and every match is tough."
"I'm very happy because I'm over the injury and at one of the greatest tournaments in the world."
