Serena Williams cruised into the third round of the French Open with a straight-set victory over Japanese qualifier Kurumi Nara.
The 23-time Grand Slam champion beat 27-year-old Nara 6-3 6-2 in one hour seven minutes.
American 10th seed Williams will play compatriot Sofia Kenin next after her opponent, Canada's Bianca Andreescu, withdrew with a shoulder injury.
"I'm very serious when I play, but I'm happy," said Williams, 37.
The first set remained on serve for the first seven games, with world number 238 Nara proving a decent match for her opponent in the opening exchanges.
But Williams eventually broke Nara's serve to move 5-3 ahead before serving out the set.
She dominated the second set, breaking Nara's serve twice before serving out the match with an ace, having not dropped a point in the final game.
