Jalen DeLuca and his hero New York Yankee James "JY" Yager must team up to prove themselves in this sequel to Tim Green and Derek Jeter's New York Times best-selling novel, Baseball Genius.

Jalen DeLuca loves baseball. He's playing for his summer travel team and trying to win a regular spot in the rotation. But Jalen's got more than talent on the field. He's a baseball genius who can analyze and predict almost exactly what any pitcher is going to do with his next pitch. He can't quite explain how he knows, he just does. His unique ability helped him to save the career of New York Yankee star baseman, James "JY" Yager, and now Jalen figures he'll be almost part of the team. Or will he?

After a power struggle with the Yankees GM and a failed negotiation with Cat, JY strikes out on his own to show he can still hit in the majors without the help of Jalen's baseball genius. Disappointed, but focused on his own baseball career, Jalen tries to carve out his own spot with the Rockton Rockets.

When things go wrong for both of them, JY works out a deal with Cat, bringing the pair together again. With JY's help, Jalen and Daniel are able to join a travel team from a nearby rival town who will face off against the Rockets in the championship game of an elite tournament in Boston. With the pressure mounting for JY to perform at the Green Monster and Jalen intent on paying back his former team, they'll have to pull off the ultimate double play if they're both going to succeed.
