Hanescu, a semifinalist in Casablanca last month, broke his opponent five times and saved the six break points he faced. The Romanian will next meet fourth-seeded Andy Roddick of the United States.
"I'm really happy that I won so easily, I don't know what happened because he is a good player" Hanescu said. "I came here to feel the court, to feel the balls. My goal is to play well here ahead of the French Open."
The clay-court Grand Slam tournament starts on Sunday at Roland Garros.
