Brad Lidge is an expensive closer- $11.5M.
Ryan Madson is an expensive setup man- $4.5M.
Jose Contreras is a moderately priced setup man and cheap closer- $2.5M.
Lidge has an option for $12.5M next season, or a $1.5M buyout (the likely route). Madson is a free agent after 2011 and will likely market himself as a closer. Then there is Contreras who is signed at an identical $2.5M for 2012 and has an option for the same in 2013. The man is old, but has reinvented himself as a reliever. He has shown composure and been successful during his limited time in the closer's role, both last year and so far this year. If Contreras continues to get the job done (85% save rate or better), then this could be an area where the Phillies save some money going forward until one of their young gun relievers are ready from the minors (Michael Stutes, Michael Schwimer, Phillip Aumont, BJ Rosenberg, or Eric Pettis).
Relying on an ancient armed reliever may not be the best plan for a contending team, but I'm just trying to think outside the box here. Remember, funds will be limited going forward due to massive contracts (Utley, Howard, Lee, Halladay).
