6. P Michael Fulmer and P Luis Cessa to Detroit Tigers for OF Yoenis Cespedes (July, 2015)

Even though Michael Fulmer is trending toward the American League Rookie of the Year, the Cespedes trade remains justified and, at this point, one of the best trades in franchise history.

That ridiculous post-deadline stretch in which Cespedes was seemingly impossible to get out – or limit to less than extra bases – was a tremendous cause for the Mets’ eventual playoff berth.
