Some of these decisions are pretty clear:
Williams: Under contract, so not really any decision to be made unless the Mets wanted to eat tons of money and trade him at his lowest possible value. While his role in the 2027 bullpen is yet to be determined, he isn’t going anywhere.
Myers: not yet arbitration eligible and will still have an option year in 2027. With a <$1M in salary obligation next year and flexibility, obviously should be retained.
Senga: obviously very early but making him a reliever seems like a great idea. Under contract for 2027 at $14M and then a free agent. Will be on the team next year unless (a) he’s so bad as a reliever that the Mets give up and eat the money; or (b) he’s so good as a reliever that he regains value and is traded.
Garrett and Megill: Will be tendered contracts as long as they’re healthy/recovering well. This decision was already telegraphed when the Mets extended contracts to both in 2026 despite clearly never going to pitch all year. Should be ~$5M (combined) to retain them for 2027,
Everyone else would need to do quite a lot to justify remaining, in large part because there are 7 key prospects that need to be added to the 40-man roster this offseason to remain under Mets control: Jefferson Rojas (new #1 prospect; acquired in Holme/Taylor deal), Gary Gill Hill (acquired in Peralta deal), Zach Franklin (acquired in Brazoban deal), plus Clifford, Wenninger, Suero, and Reimer.
A few 40-man roster spots will open because Stock, Pintaro, McDermott, and Weisenburger aren’t particularly likely to hold on them. But there’s still a crunch.
If I had to currently rank the remaining relievers in order of likelihood of being on the Mets in 2027:
Lavendar, Nunez, Duarte, Cionel Perez, Yan, Xzavion Curry, Hagenman, field
