Cubs: Remlinger is too valuable as a lefty, so Veres who has closing experience is the #1 guy who would replace the 6-fingered wonder, Alfonseca.
Expos: Scott Stewart's #'s are VERY solid for a guy who gets no pub. He has some chips removed from his elboy back in October, but that should actually benefit more than hinder his abilty. He is a good bet to be the closer for the season.
Padres: Trevor Hoffman has not even begun to throw a baseball yet and he may not be back until June or later. Jay Witasik is the likely first choice to close, followed by Brandon Villafuerte.
Giants: Keep an eye on Robb Nen this Spring as he is also coming off of surgery and may not be ready to handle 100% of the closing duties.
Marlins: It is Looper's job to lose, but Spooney has serious closer stuff.
I usuallly try to find $1 MR guys like Remlinger, Felix Rodriguez and Octavio Dotel who could get you 10 "vulture" saves if you are lucky.
