Miami Marlins catcher Jacob Stallings has been less than impressive this season, despite his recent hot streak. In the past eight games he has played in, Stallings is hitting .316 with five RBI and an OPS of .796. The problem is that even after that eight game hot streak, his season totals at eight RBI and a slash line of .161/.227/.218 and an OPS of .445. Those numbers are unacceptable even for a veteran catcher who adds value with defensive prowess, which Stallings also is lacking.
Kim Ng has made it public that they are shopping for improvements at catcher and shortstop and it seems that Stallings will be on his way out, especially if they can get a more veteran catcher. There aren't many options in the market for Stallings and I would gather his only value would be as a backup, so his trade value is limited, as his time as a Marlin.
