The New York Mets have some retooling to do this winter after shipping off three key bullpen arms at the trade deadline. After a second consecutive disappointing season in which they missed the postseason, the Mets are going to have some work to do if they want to change the narrative for 2027.

Relievers Luke Weaver, Huascar Brazoban, and Brooks Raley were all shipped off in favor of prospects as New York sold at the deadline, but their holes need to be filled before the start of 2027 (assuming baseball will be played as normal by next spring). Here are three relievers the Mets need to take a look at this free agency window.

Certainly the most valuable reliever to hit the open market this winter, the left-hander is coming off another sub-3.00 ERA campaign while throwing the most innings of his career (86). Morejon’s 2.37 FIP and 11.2 SO/9 at just 27 years old have him set up for a big payday in the coming months.

Luckily, under owner Steve Cohen, no number is too much when it comes to contracts. Morejon has served as the setup man with the San Diego Padres, but he could come into Queens as the closer in 2027 after current closer Devin Williams’ step back last season. With the money and role to entice Morejon, the Mets are real contenders for the best reliever on the market if he wishes to leave San Diego.

If New York wants to look for another lefty reliever, Newcomb is a great second option. Providing over 90 innings for the surprise Chicago White Sox in 2026, the 33-year-old’s 3.21 FIP earned him the highest bWAR of his career at 2.0. His 1.76 career ERA in the postseason is an additional plus for a Mets team that’s desperate to make a splash in 2027.

Blackburn was with the Mets as recently as 2025, but his full-time switch to the bullpen has given a second life to his game. His 1.69 ERA across 85 innings made him the third-most valuable pitcher on the New York Yankees roster in 2026.

Though his stint in Queens last time around didn’t go to plan, perhaps a return in his new role would make those memories disappear. And of course, it would feel great to snag such a valuable piece from their cross-town rivals.

There are many other valuable relievers to hit the market in free agency, and even if the Mets can't pick up any of these three, there are still plenty of ways to bolster their bullpen. If postseason is the goal next fall, they're going to have to act on it now.
