Keith Foulke threw for over twenty teams last week in attempt to make a comeback, and many teams were impressed by the workout. Among them, the Diamondbacks appear to be the most aggressive. Foulke did not pitch last season but was arguably one of the best closers in the game in the early 2000s. I think this is a solid move for the Diamondbacks. The Diamondbacks surprised many when they traded Jose Valverde to the Astros and although they have potential closer Brandon Lyon, signing Foulke would allow them to play Lyon where he pitched successfully all last season. I'm sure this will be a one year contract loaded with incentives, but it should be good nonetheless.
