Holder Ana Ivanovic underlined her credentials for a second French Open title with a 6-0, 6-2 demolition of Czech Iveta Benesova in the third round on Friday.
The Serbian eighth seed needed just over an hour to set up a meeting with either ninth seed Victoria Azarenka of Belarus or Spaniard Carla Suarez Navarro, seeded 22nd.
Ivanovic saw off two break points in the opening game before bulldozing through the first set in 23 minutes.
Benesova, seeded 32nd, then picked up her game but Ivanovic was simply too good, wrapping up victory on her first match point with a forehand winner.
