3. Mets pitcher Tylor Megill
Both Taijuan Walker and Carlos Carrasco have been slowed down this spring with injuries. If either one isn't fully stretched out, I expect the Mets to strongly consider bringing someone like David Peterson or Tylor Megill to New York for Opening Day.
While Peterson had an impressive rookie year in 2020, I believe Megill is the better pitcher right now. Peterson really struggled last season before his season-ending injury while Megill flourished in his unexpected call to the show.
Megill made 18 starts last season which ended up being the third most on the team. In those starts, he went 4-6 with a 4.52 ERA. That ERA was not reflective of how he pitched for much of his time in Queens, as he really struggled to finish his season. i believe that was due to working a much bigger load than he had at any time in his life.
Megill has looked excellent thus far in the spring, throwing 6.2 innings without allowing an earned run. I believe he can make the team and follow either Walker or Carrasco if they can't sustain a big enough pitch count right out of camp.
Megill can also start games if either one of those arms end up on the IL. Preferably he'd be in AAA, but he's the best arm outside of the starting rotation that can pitch in a starter type role out of camp.
