For one good reason they stick with Borowski and don't slot in one of the Rafaels, see the Fausto Carmona experiment. This year, he's a Cy Young candidate, a 19-game winner who's at times unhittable. Last year, he was the same pitcher trying to close out games and an all-around mental mess.

In addition to leading the league in saves, Borowski's also a known mental commodity when it comes to closing out games.
