Ons Jabeur said Roland Garros must "try more" when it comes to promoting women's tennis in the tournament's prime time spot.

In the last two years, only two women's singles matches have featured in a total of 20 allocated nighttime sessions.
"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 Tunisian world No 9 Jabeur after reaching the last 32 by seeing off Camila Osorio in three sets on Wednesday.
"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."
Over the first four days of the 2024 tournament, all night sessions have featured men's singles – with world No 1 and defending champion Novak Djokovic, second-ranked Jannik Sinner and three-time major winner Andy Murray featuring.
For Jabeur, the standout match on Wednesday was the duel between women's world No 1 Iga Swiatek and fellow four-time Grand Slam champion Naomi Osaka.
However, that tie closed out the afternoon session on the showpiece Court Philippe Chatrier with Sinner's clash against French veteran Richard Gasquet taking the prime time night session.
Jabeur is hopeful tournament director Amelie Mauresmo, a former world No 1, will succeed in the scheduling balance.
"I'm not gonna lie about it. I think Amelie is doing an amazing job and is trying to change that, but these things, they take time," added Jabeur.
"I wish I can see the change more. I wish I saw Osaka and Iga's match today as a night session. But it's a choice. I understand that. Maybe the prime time is now.
"I will keep pushing and I wish really to see promoting more women's sport in general and women's tennis in general."
