At the start of the off-season, Daniel Zamora pretty much had to make the roster. He was the only lefty in the Mets bullpen that existed. As the off-season continued the Mets signed several players to compete with Zamora. First Justin Wilson signed a major league deal for a good chunk of money making Zamora expendable from the roster. Spring Training started and Avilan started to pitch his heart out, pitching himself onto the roster.
So Zamora is not on the active roster right now, but that could change. He had a good debut, although short, last season:
2018: 9 IP, 3.00 ERA, 2.38 FIP, 1.0 WHIP, 16 K/9, 0.3 WAR, 2.26 DRA
Obviously a cup of coffee, lets take a peak at what projections think he’ll eventually do this season:

(Citations: Baseball Prospectus (BP) projections are from the Baseball Prospectus annual which can you can get here. It’s highly recommended. ESPN projections can be found here. ZiPS can be found here. Steamer can be found here. Baseball Reference projections (BR) can found on the players BR page which linked elsewhere on this article. )
So they didn’t project a full season of work for Zamora, probably about half a season of work but those numbers are surprisingly good! The usual suspects, BP and BR are the most down on his 2019. ZiPS and Steamer are very, very close in their ERA projections. ESPN is overboard in the opposite direction.
The projections for Zamora leave me with a lot of hope for him this season. Let’s see what he does in the minors first.
