At the Cincinnati Open, the spotlight has mostly been on the usual heavyweights—Jannik Sinner and Carlos Alcaraz both cruising past opponents with ease. But this year’s story has an unexpected twist, with a new name forcing his way into the conversation.

ATP No. 1 Jannik Sinner is bidding to become the first back-to-back Cincinnati Open men's singles champion since Roger Federer.

Unless you’re a tennis die-hard, you probably didn’t know much about Terence Atmane before this week. The 23-year-old Frenchman is ranked as the World No. 136 and has played just 14 matches on the ATP Tour in the last calendar year.
