From New York Times bestselling authors Tim Green and Derek Jeter comes a collectible boxed set that features all three novels in the Baseball Genius series! 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. He can analyze and predict almost exactly what a pitcher is going to do with his next pitch. He can't quite explain how he knows, he just knows. In Baseball Genius , Jalen's unique ability helps him save the career of the Yankees star baseman, James "JY" Yager, but it also brings him into conflict with the GM of the Yankees who'd like nothing more than to see JY off the team. In Double Play , Jalen and JY have to team up for the ultimate play when they both face competition in Boston.

And in Grand Slam , JY is sidelined by an injury, and Jalen focuses on his own on-field efforts. However, the media is still interested in the "Calamari Kid" and Jalen begins to get a little full of himself. Now Jalen's friends are feeling left out and a little angry. Maybe all this baseball genius stuff isn't as great as it's cracked up to be. Will Jalen figure out how to use his baseball genius both on and off the field?.
