The Lucky Baseball Bat by Matt Christopher
Martin desperately wants to prove himself to his teammates on the Tigers baseball team, but he hasn't made much of an impression yet. Then an older boy named Barry Welton gives him an old bat, and suddenly Martin feels like a winner. His playing improves, but just when it looks as though things are going his way, he loses the bat - as well as his confidence. Will Martin be able to continue his winning streak without the bat?
