School of Hard Knucks HC

When a father discovers his baseball-crazed sons have the knack for the knuck, they begin a decade-long, cross-country quest to perfect the pitch. Along the way they meet the greatest to throw it, the scientists investigating its mysterious movement, sabermetricians, and executives who hope to resurrect it. The aspiring knucklers also learn lessons they'll use off the field, proving that when life throws them curves, they have something to throw back. (From the publisher.)
