Gus, Richie and Clark are three underdogs who spent a great deal of time on the bench when they were kids. Now, they're getting a second chance. Mel is a local billionaire whose son Nelson is always being intimidated by the other kids. One day, Gus and Clark rescue Nelson from a bunch of bullies on the baseball field. When Max tells his father about the incident, Mel makes Gus, Clark and Richie a tantalizing proposition: He will put up the money for them to travel and play in a tournament against the young baseballers as a way of helping his son and other nerds like him to exact revenge against the bullies of this world. It will be called "Mel's Tournament of Little Baseballers and Three Older Guys." The winner will get the greatest stadium ever built--at Mel's expense. In order to prepare Gus, Richie and Clark for the tournament, Mel hires baseball legend Reggie Jackson to train them. Reggie works with them on timing by having them sit in the back of a truck as it drives down the street, swinging a bat and demolishing mailboxes. He also teaches them fielding by tossing a hot potato at them, which they catch barehanded and toss quickly to one another. Amazingly, the training pays off and they become an inspiration to benchwarmers everywhere.
