Iga Swiatek and Naomi Osaka served up a genuine classic, with the current world number one just edging out the former world number one.
Meanwhile, Carlos Alcaraz laboured to a four-set victory over Dutch qualifier Jesper de Jong.
Here, the PA news agency looks back at day four at the French Open.
…and the tournament. Swiatek came through a titanic second-round clash with fellow four-time grand-slam champion Osaka to reach the third round. Osaka looked set to pull off her biggest win in years when she led the defending champion 5-2 in the third set. But the 26-year-old from Japan will have nightmares about a missed forehand as Swiatek survived a match point to come from brink of defeat and win 7-6 (1) 1-6 7-5.
The Paris weather is not playing ball so far this week, and there was hardly any play possible on the outside courts on day four. Only nine matches were completed, all under the two roofs. The forecast does not look likely to improve over the coming days either.
Nothing to see here, at least until the doubles starts. Andy Murray and Dan Evans should be fun, if they ever get on the court. Katie Boulter and Heather Watson have also been pushed back until Thursday, at the earliest.
