Marlins closer Leo Nunez has been the subject of numerous trade rumors as the team contemplates cashing in a good but not great reliever whose value is inflated by his save total.
If they do end up moving Nunez before the July 31 trade deadline manager Jack McKeon told Clark Spencer of the Miami Herald that Edward Mujica would take over as the new closer.
Mujica, who was acquired from San Diego in November as part of the Cameron Maybin trade, has a 2.85 ERA and 35/5 K/BB ratio in 47 innings for the Marlins after posting a 3.80 ERA and 148/25 K/BB ratio in 163 innings for the Padres.
In three seasons as a closer Nunez has a 3.63 ERA while converting 82 percent of his save chances, which is basically right around the MLB average for ninth-inning save opportunities. Getting a solid prospect or two for him, handing Mujica the gig, and then perhaps dealing Mujica for a solid prospect or two in a couple years would make all kinds of sense for the Marlins.
