Back in 2015, the New York Mets made the mistake of trading Michael Fulmer to acquire Yoenis Cespedes. No, it was not a mistake to obtain Cespedes, but rather, Fulmer was far too high a price to pay. As it would turn out, the Mets needed starting pitching the ensuing two seasons where Fulmer was winning Rookie of the Year and being named an All-Star.

Well, from there, Fulmer had some injury prone years and moved to the bullpen. For his part, Cespedes needed double heel surgery, and then, he would have an incident falling off his horse or something with a feral hog during his rehab. The details are still murky.

Regardless, the Detroit Tigers received a 12.2 WAR out of Fulmer and a prospect at the trade deadline. The Mets received an epic run from Cespedes amounting to a 2.1 WAR and not postseason production at the plate past Game 3 of the NLDS. In essence, the Mets made a win-now trade and didn’t win.

Fast-forward to 2023, and Fulmer is a free agent while Cespedes is trying to get back into the majors. The Mets are also looking to build a bullpen which can get them their first World Series since 1986. It already looks formidable with the following relievers in place:

• Edwin Diaz
• David Robertson
• Adam Ottavino
• Drew Smith
• Brooks Raley

There are other pitchers in the mix, but these are the relievers who are guaranteed. With five starters, that leaves up to four more relievers who can be added. The presumption is at least two of Joey Lucchesi, Tylor Megill, and David Peterson will start the season in Triple-A to provide organizational starting pitching depth.

That probably leaves pitchers like Jeff Brigham and John Curtiss on more of a solid footing to make the Opening Day bullpen than they probably should. Even with those names likely to make the bullpen, the Mets are still at least one arm short.

Fulmer, 29, would be an excellent fit. As a reliever, he has a 128 ERA+. As per Baseball Savant, he does an exceptional job limiting hard contact and barrels. We’ve also seen Jeremy Hefner work well with pitchers how have a similar repertoire. All told, he probably remains the best arm remaining on the market.

While we are very confident in this Mets roster, they probably remain an arm short in the bullpen. Fulmer would go a long way to resolving that issue and make this Mets team even better. All this time later, the Mets now need to sign Fulmer instead of trading him to try to help put this Mets team over the top.
