The Open 13 Provence event in Marseille traditionally runs in February and will run this year from February 5th till the 11th. The ATP 250 event generally draws a pretty solid field, with at least one or a few Top 10 players every year, but this year's list will be a bit weaker.
It's especially weaker as of January 29th, 2024, since top seed Jannik Sinner won't be playing at the event. He has played at this event before, though he skipped last year's edition despite initially signing up to play.
The same thing is happening this year, though this year, he has a very good reason for that: winning the Australian Open. The Italian had the best moment of his career recently in Melbourne when he turned around a 0-2 deficit into a 3-2 win against Daniil Medvedev to win his maiden Grand Slam trophy.
It was a tough and long two weeks Down Under for the Italian, so it's only natural he wants to rest up after that. He also doesn't need to play in Marseille, as the ATP 250 tournament would only present a risk of injuring himself after two grueling weeks.
He never shared what his schedule might look like after Australia, but many assume that he would likely skip everything until the Rotterdam Open, which is another event he played in the past.
He made the final last year but lost against Daniil Medvedev, no less, despite giving the Russians a lot of problems. After his Marseille withdrawal, Sinner is scheduled to play Rotterdam next.
That is in the week after Marseille, starting on February 12th. We'll see if he skips that event as well, considering the circumstances, but as of now, that's his next event.
The Marseille Open tournament organizers also shared that they are negotiating with Alexander Zverev, as they want to find a replacement for the top player at their event.
