Reading the Signs by Keira Andrews

This hot-headed rookie needs discipline—on and off the field.

Pitcher Nico Agresta decided a long time ago he can never act on his desire for men despite a hopeless crush on his big brother’s teammate Jake Fitzgerald. Nico is desperate to live up to his Italian-American family’s baseball legacy, and if he can win Rookie of the Year in the big leagues like his dad and brother, maybe he can prove he’s worthy.
At 34, veteran catcher Jake just wants to finish out his contract and retire. He lost his passion for the game—and life—after driving away the man he loved. He swore he’ll never risk his heart again.

Then he’s traded to a team that wants a vet behind the plate to tame their new star pitcher.
Jake is shocked to find the gangly kid he once knew has grown into a gorgeous young man. Tightly wound Nico’s having trouble controlling his temper in his quest for perfection and needs a firm hand. Jake fights to teach him patience and restraint on the mound—but when the push and pull explodes off the field, can they control their hearts?

Reading the Signs by Keira Andrews is a gay sports romance featuring hurt/comfort, first times and exploration, an age gap, and of course a happy ending.
