Serena Williams began the defense of her French Open title with a 6-2, 6-1 victory Sunday over 138th-ranked Alize Lim, a wild-card entry from France.
The top-seeded Williams dictated most points and wound up with 30 more winners - but also 24 more unforced errors - than Lim.
Williams is a 17-time major champion who was facing a woman making her Grand Slam debut. Still, there was a bit of shakiness from the 32-year-old American as she served out the final game, erasing four break points and needing five match points to close things. Williams saved all seven break points she faced in the match.
She improved to 54-1 in first-round matches at majors. The only loss came at the 2012 French Open against 111th-ranked Virginie Razzano.
