His shoulder might be hurting, but now he's willing to put everything on the line in one last game. Between each pitch, we see flashbacks that concentrate on Billy and Jane and their uncertain future together. She's in the process of accepting a job in England, so it looks like she has given up on Billy. With Jane on his mind and with his future in baseball in doubt, Billy takes the mound and begins pitching the game of his life. Between pitches and between innings, Billy's thoughts tend to drift, but when it's time to deliver the next pitch, he suddenly shuts out everything.
Nothing exists except for the batter and catcher.
On the debit side, however, the film never gets very far beneath the surface of Billy Chapel. Ultimately, we know much more about Jane and her insecurities than we do about Billy. However, Billy Chapel never becomes much more than a generic baseball veteran. Part of the problem is the scenes between Billy and Jane aren't particularly imaginative. There are few surprises.
