Serena Williams will be favourite for a fourth French Open title if she survives into the second week, former men's champion Jim Courier believes.
The Russian appeared to be cruising at 6-1 3-1 ahead but Holland's Richel Hogenkamp suddenly had her on the ropes, taking the second set and racing 3-0 ahead in the decider.
Barty took the first set 6-3 with typically combative, speedy play and Williams had it all to do to turn the match around.
Sharapova, who made a comeback to the French Open for the first time since 2015, after serving a doping ban in 2016 and refused a wildcard entry in 2017, comfortably saw off Croatia's Donna Vekic, 7-5, 6-4. "And then if I need to train again, I have X time in training because of her nap schedules".

"I lost the first set and I thought you know I've got to try harder".

'When you realize you have to fly back to SF for @initialized business tomorrow and you will miss watching @serenawilliams and @venuswilliams win their 1st doubles match of #RG18.
This match could be exactly what Serena Williams needed.
Social media seemed to approve of Serena's look and her game. "It was something I was born with, thank goodness", Serena said. "I want to play my game, regardless of who is on the other side".
