NEW MET - RP Jim Henderson

The Mets made a low-risk, potential high-upside acquisition Thursday, signing reliever Jim Henderson to a minor league deal with an invite to spring training.

Henderson, 33, had his best season in 2013, when he went 5-5 with a 2.70 ERA and 28 saves in 61 appearances for the Brewers. The right-hander spent most of last season at Triple-A in his comeback from shoulder surgery.

Mack - Henderson becomes the second cheap addition (Stolmy Pimentel) that might wind up in a 2016. Mets bullpen that will include Jeurys Familia, and Addison Reed. 

My guess is Josh Edgin and Jenrry Mejia are locks to return once they are healed (or freed), but, past that, who the heck knows.
