Baseball Genius Books in Order

The Baseball Genius books, cowritten with Derek Jeter, follow Jalen DeLuca, a smart, baseball-obsessed kid whose extraordinary feel for pitching turns his ordinary life upside down. Jalen can read a pitcher’s grip, body language, and habits so well that he can predict the next pitch with uncanny accuracy.

In Baseball Genius, Jalen’s dad is struggling to keep their small-town diner afloat, and money for travel-ball fees has dried up. Desperate to stay on his team, Jalen sneaks into the home of New York Yankee star James “JY” Yager, planning to steal a couple of signed balls to sell. He is caught, of course, but a wild idea saves him. If he can help JY break out of a brutal slump using his pitch-reading gift, maybe they can help each other.

The uneasy partnership that follows gives readers a behind-the-scenes look at big-league baseball, from batting cages and scouting reports to the way a star’s confidence can crumble. Jalen has to juggle school, his own games, his job at the diner, and the secret late-night calls that keep JY’s career alive.

In Double Play, Jalen wants to focus on earning a secure role on his travel team while JY fights to prove he can still hit without a kid in the stands signaling pitches. When both start to struggle, circumstances pull them back together. A high-stakes tournament in Boston pits Jalen against his former teammates while JY faces a make-or-break appearance at the famous Green Monster, tying both of their futures to one risky plan.

Grand Slam turns more attention to Jalen’s own development. With his reputation growing, he faces jealous teammates, intense parents, and coaches who are not sure what to make of his unusual talent. The games are bigger, the crowds louder, and every mistake seems magnified. Jalen has to learn how to use his “baseball genius” without letting it define him or make him a target.

Throughout the series, Green and Jeter balance fast, technical baseball action with themes of honesty, loyalty, and hard work. Jalen’s special ability might give him an edge, but it is his effort, friendships, and willingness to own up to mistakes that keep him in the game.
