Paris: World number one Serena Williams huffed and puffed into the second round of the French Open with a 6-2 6-1 win over local favourite Alize Lim on Sunday.
The defending champion sprayed court Philippe Chatrier with unforced errors in a match that was not as one-sided as the score line suggested.
Williams was so confident she would crush her training partner that she warmed up for the encounter wearing a blazer suit, but Lim proved to be a tenacious opponent despite her ranking of 138.
In the opening set, Lim claimed 27 points but surprisingly 23 of those came thanks to Williams`s unforced errors.
Williams wasted four match points in the second set before wrapping it up on the fifth when her opponent sent a backhand long.
