The deal, which is worth an average of $9M per year and has an option for a fourth year, should give the Marlins one of the most dominant closers in the game. In the 2011 season, Bell pitched 62 and 2/3 innings with the San Diego Padres, earning 43 saves, 31 shutdowns, and just 8 meltdowns.
Last year, the Marlins employed Leo Nunez, now (or always, in a way) Juan Oviedo, as their closer. In his 64+ innings as the 9th inning man, he managed 36 saves with a below average 4.06 ERA and 3.96 FIP.
Interestingly, Nunez had the same number of meltdowns as Bell while also managing two more shutdowns.
