5 offseason changes the Mets need to make if they miss the playoffs again

5) The Mets need to leave the DH spot open to rotate different players through

J.D. Martinez was a great addition by the Mets in the offseason. Capable of helping to carry the Mets to the postseason, the main negative about him remains the inability to play a position. Having him as the everyday DH takes some options away from Carlos Mendoza. When Martinez is slumping, he’s a net negative because of the zero participation trophies he wins on defense.

At the price Martinez was willing to sign, the Mets had no choice but to bring him in. Next year, unless something similar happens again, they should aim to leave the DH spot open. Instead of one guy, let the position players rotate through.

This can help a guy like Starling Marte stay healthy and effective. Francisco Alvarez could benefit from the occasional start as the DH. Let’s get Francisco Lindor off his feet for a little longer to get him through the long season.

Heaven forbid the Mets ever experience a position player of importance require Tommy John surgery and become unavailable altogether because the club already has a DH-exclusive player on the roster. This isn’t a required change because of who Martinez is. Instead, it’s more about how beneficial it would be to give a different player a half-day each night. The Mets have successfully mixed and matched multiple position players. One more spot to toy with can help out.
