Duke-ing It Out by Jami Albright

It’s game, set, and match when this pro football player turned trainer squares off against a gorgeous tennis player with an attitude as big as Texas.

Duke Wayne returns to his hometown for one reason and one reason only—reckless pro tennis star Sienna Ramsey has lost her ever-lovin’ mind. His feisty client is ready to throw her career away in favor of a simple life.
It doesn’t get much simpler than tiny, gossipy Ryder, Texas. Duke figures a few days with the locals should have the infuriating woman begging for a stadium full of cheering fans in no time at all. But Sienna and the small town go together like fleas on a farm dog.
Duke’s plan blows up in his face when he discovers there’s more to Sienna than a smart mouth and a killer backhand. The closer they get, the harder it is to keep things professional.
What in the hell is a high-performance trainer to do when he stops thinking about his client on the court and starts fantasizing about her between the sheets?
