The bigger issue seemed to be why there were so many empty seats on Court Philippe Chatrier for a high-quality and absorbing contest between two of the WTA Tour's brightest stars.

Starting third in the day session on the main show-court, the match started at 17:37 local time [16:37 BST] and finished at 20:34.

You could only wonder where else the Parisian ticket-holders had headed.

"Osaka vs Swiatek is a brilliant watch. WTA need to do more to capitalise on these match ups!" Andy Murray, the British former world number one, said on X, external.

The swathes of seats were certainly not a good look.

Had the match been put on in the night session, Swiatek and Osaka would likely have been enjoyed by a much fuller crowd.

It led to more questions about the French Open's scheduling policy, which has been criticised in recent years.

Instead of Swiatek versus Osaka, Wednesday night's prime-time slot saw men's second seed Jannik Sinner beat Frenchman Richard Gasquet in straight sets.

All four night sessions so far at the 2024 tournament have been men's singles matches and a fifth - between home favourite Gael Monfils and Italy's 30th seed Lorenzo Sonego - is scheduled on Thursday.

Only two womens singles matches featured in a total of 20 night sessions across 2022 and 2023.

Tournament director Amelie Mauresmo - a former WTA world number one - was criticised two years ago for suggesting the men's matches were more appealing.

Three-time major finalist Ons Jabeur thought Swiatek versus Osaka should have had a night-session match, although Swiatek later diplomatically said she preferred playing in the day.

Jabeur called on the French Open to promote the womens game more and hopes Mauresmo can oversee meaningful change.

"I'm going to get in trouble again, aren't I? Listen, I know they're trying here - I wish they'd try more," said the Tunisian world number nine.

"It's not something we'll change in a day. I'm watching TV every day. A lot of men's matches, more than women, and it is the truth."
