A very solid start from Krejcikova, who has found her rhythm quickly. She breaks after a marathon opening game, then follows up with a hold to love.
Sunday saw Serena Williams and Roger Federer bow out, with Federer withdrawing before his fourth-round match against Matteo Berrettini.
Ons Jabeur and Coco Gauff will begin at 11am (BST), but over on Suzanne-Lenglen, play has already started. Sloane Stephens, a former finalist here who has slipped down the rankings, is taking on world No 33 Barbora Krejcikova in a battle between two unseeded players.
Order of play
Court Philippe-Chatrier Ons Jabeur v Coco Gauff  Novak Djokovic v Lorenzo Musetti
 Rafael Nadal in Jannik Sinner Evening: Marta Kostyuk v Iga Swiatek 
Sloane Stephens v Barbora Krejcikova
 Diego Schwartzman v Jan-Lennard Struff
 Sofia Kenin v Maria Sakkari 
Bonjour, tout le monde. Novak Djokovic and Rafa Nadal have successfully held off the Next Gen – but what about the Next Next Gen? Both players face teenagers today, with Djokovic up against Lorenzo Musetti before Nadal plays Jannik Sinner. Both are Italian, and both were three years old when Nadal first won the French Open in 2005.
There are more slam winners in action today, in the form of Sloane Stephens (who will be on court momentarily) and Sofia Kenin, who plays Greece’s Maria Sakkari. There’s plenty of US interest, even with Serena Williams going home – not least in Coco Gauff, chasing her first slam quarter final place today. Gauff wasn’t born when Serena first won here in 2002. Life, it comes at you fast.
