Ten-year-old baseball fanatic Yankee Irving (voiced by newcomer Jake T. Austin) is always the last one picked for sandlot baseball games. But when Babe Ruth's prized bat is stolen during the 1932 World Series, Yankee steps up to the plate to help retrieve it for his beloved idol. He embarks on a wild cross-country journey that teaches him the stuff real heroes are made of, and along the way, Yankee learns the importance of perseverance and the true meaning of friendship.
