David Peterson has been an unsung hero for the New York Mets this season. This Mets rotation hasn't really been fully healthy at the same time yet. Even when Jacob deGrom and Max Scherzer finally pitched at the same time Carlos Carrasco went down with injury.
With the rotation constantly dealing with injuries, David Peterson has been the guy relied on to make starts at unknown times for the Mets. He'd go back and forth from Syracuse and when tasked with starting a game he's done as well as anyone could've imagined in this weird role.
Unfortunately, with the Mets getting healthier and with Peterson struggling a bit lately, I think he might have pitched his way off of the playoff roster.
David Peterson doesn't have a spot on the Mets playoff roster when healthy.
The Mets postseason rotation seems to be pretty set. Jacob deGrom, Max Scherzer, and Chris Bassitt are obvious locks. Carlos Carrasco hasn't allowed more than three earned runs in his last 11 starts, dating back to June 28th. He seems to be the leading candidate for the fourth starter spot right now.
Taijuan Walker is going to make the roster in some capacity most likely, and so is Trevor Williams as the team's long reliever. The Mets don't really need a third long reliever.
Edwin Diaz, Adam Ottavino, and Seth Lugo are the Mets high leverage arms. Mychal Givens and Trevor May despite their inconsistencies this season are veteran arms that will also be on this postseason roster.
Tylor Megill and Drew Smith are about to return from lengthy stays on the injured list. Both figure to be a part of the postseason picture as well.
This leaves David Peterson off of the roster even by default. However, if he was pitching well lately I'm sure the Mets could find a way to squeeze him onto the roster.
Peterson won't be the pick to start a postseason game. This team has too many accomplished veterans who have been there before and it just doesn't make sense to risk losing a game if Peterson isn't comfortable in the high anxiety situation.
Peterson as a reliever could be interesting, but I really don't see it happening at this point. Seth Lugo is the teams lefty specialist even though he throws right handed. He's held lefties to a really solid .466 OPS in 99 plate appearances against him this season.
The Mets do have Ottavino and Diaz who can be trusted against just about anyone. Peterson shouldn't be thrust into this main lefty role because he just hasn't done it before.
When given the chance against the Yankees earlier this season he walked Anthony Rizzo before giving up a home run to Gleyber Torres to tie the game.
I understand this was his only chance, but baseball isn't fair. He can prove me wrong if given the opportunity down the stretch but I'm not sure that'll happen.
It's disappointing that the Mets didn't address the left handed reliever at the trade deadline, but they do have guys who I'd trust more in a high leverage relief role than David Peterson.
Peterson has walked 4.2 batters per nine which is just too much for a high leverage arm for my liking. He seems to let the walks spiral a bit out of control at times when in trouble which the Mets cannot afford.
Due to a roster crunch and the way Peterson has pitched when given the opportunity in the roles he'd have a chance at I believe he will not make the postseason roster.
