World number one Novak Djokovic fought back from a set down to take control against Roberto Bautista Agut when rain stopped play at the French Open.
An out-of-sorts Djokovic recovered an early deficit to lead 3-6 6-4 4-1 when the fourth-round match was interrupted for a second time.
Serena Williams and Andy Murray are scheduled to play later on Tuesday.
Second seed Agnieszka Radwanska and sixth seed Simona Halep were both beaten in the women's draw.
Poland's Radwanska led Bulgarian Tsvetana Pironkova by a set and a break in their match held over from Sunday, but lost the first 10 games on the resumption, eventually going down 2-6 6-3 6-3.
