Meet Bob, the Major League’s legendary cleanup batter who can’t run, can’t field, and can’t play under pressure.

Together with his funky friends, Youngman “The One-way Runaway Train” (brawling 3rd baseman), “Stink Bug” Jo (2nd base conman), and “The Game Breaker” Jack (relief pitcher with a flea’s heart), the underdogs will reign this baseball season!
