A few of these guys are just temporary fill-ins. Andrew Bailey (draft pick), David Aardsma (trade), and Brad Lidge (trade) will take over for Fuentes, League, and Contreras, respectively, once healthy. The Blue Jays haven't had a save opportunity yet, so we don't know for sure who will fill in for the injured Frank Francisco (trade). The Rays haven't had a save opportunity yet either, and we don't know if Joel Peralta (free agent), Kyle Farnsworth (free agent), Jake McGee (draft pick), or someone else will get the call.
