Ranked No. 103 versus Grenier’s No. 258, Safiullin brings stronger recent results, including a fourth-round run at Wimbledon after qualifying and multiple upsets on grass. Grenier arrives with limited momentum, posting just a 2-8 record in recent matches and entering the main draw only as a lucky loser. The pair’s head-to-head favors Safiullin 2-1, with their most recent meeting a straight-sets win for the Russian in 2022. On hard courts, Safiullin’s superior ranking, serve consistency, and overall experience create a sizable edge that market pricing reflects.

Ranked No. 103 versus Grenier’s No. 258, Safiullin brings stronger recent results, including a fourth-round run at Wimbledon after qualifying and multiple upsets on grass. Grenier arrives with limited momentum, posting just a 2-8 record in recent matches and entering the main draw only as a lucky loser. The pair’s head-to-head favors Safiullin 2-1, with their most recent meeting a straight-sets win for the Russian in 2022. On hard courts, Safiullin’s superior ranking, serve consistency, and overall experience create a sizable edge that market pricing reflects.
