The Submarine Pitch — Matt Christopher

Bernie Shantz is thinking of hanging up his pitcher's glove for good, but his best friend, David Grant, won't hear of it. Dave convinces him that all he needs is a secret weapon -- an underhanded throw known as the submarine pitch. Bernie agrees to give the pitch a try since Dave is so keen on the idea, and since Dave can no longer play baseball himself, for some mysterious reason. Bernie is excited when his new pitch baffles one batter after another, but his excitement turns to concern when he notices how pale and tired Dave looks. Then one day Dave doesn't show up at a game, and Bernie's concern turns to dread. . . . What good is the submarine pitch without Dave cheering him on from the stands?
