Court Philippe-Chatrier, second match

Alexander Zverev (2) v Benjamin Bonzi

Zverev is a man caught between two generations. He began competing in the era of Federer, Nadal and Djokovic and now finds himself in the age of Sinner and Alcaraz. The change from one era to the other was seamless and left no time for the tall German to claim his first Grand Slam title. It is not for the want of effort – he has kept himself in contention, snapping at the heels of the champions, but to no avail.

This year, without Alcaraz, he finds himself as the No.2 seed and at least he is finally feeling fit and free of the back pain that had plagued him for months. He has never played Bonzi before but ranked 95 places above him at No.3 in the world, Zverev should get his campaign off to a flying start.

Court Suzanne-Lenglen, third match

Taylor Fritz (7) v Nishesh Basavareddy

Fritz is, in some ways, stepping into the unknown. Thanks to a knee injury, he has only been able to play one match since mid-March but that was last week in Geneva and even if he lost to Alexei Popyrin, his knee held up well. So far, so good. “The positive is my knee felt good last week playing,” he said. “[I’m] a bit rusty, obviously, but feeling good physically and excited to get back to just playing tennis and getting my level back.”

Basavareddy is seven years younger than Fritz at 21, six inches (16cm) shorter at 5ft 11ins and 30lbs (13kg) lighter. He is also the world No.158 and enters as a wildcard. Fritz is the world No.8 and a US Open finalist. Provided his knee holds up, Fritz should be the easy favourite.

Court 13, third match

Emma Raducanu vs Solana Sierra

Raducanu has come full circle. In the five years since she won the US Open under the guidance of Andrew Richardson, the list of coaches she has hired and fired has reached double figures. She parted ways with Richardson after that remarkable run in New York and she has never come close to repeating that form again. Now she is back with Richardson again and comes to Paris with the hope of finding that spark again.

“He’s someone I’ve known for a very long time, over a decade,” she said. “We have a great chemistry I think, coach/player relationship. That was evident every time we worked together. Just very happy to have him back.” Today we will learn whether that chemistry is working again.
