World number one Serena Williams wasted little time in beating Elina Svitolina in their rain-delayed fourth-round match at the French Open.
The American beat Ukraine's Svitolina, coached by four-time Roland Garros champion Justine Henin, 6-1 6-1.
Williams next plays Yulia Putintseva, who beat Carla Suarez Navarro 7-5 7-5.
Switzerland's Timea Bacsinszky beat Venus Williams 6-2 6-4, and unseeded Dutch player Kiki Bertens upset US 15th seed Madison Keys 7-6 (7-4) 6-3.
Later on Wednesday in Paris, Novak Djokovic completes his match against Roberto Bautista Agut, before Britain's Andy Murray plays Richard Gasquet.
