To this point, Jon Niese, Zack Wheeler, Bartolo Colon, and Dillon Gee seem to round out the first four spots of the rotation- which seems to be pretty solid- but the fifth spot is seemingly up for grabs. In reality, Rafael Montero and Noah Syndergaard are not going to make the roster on Opening Day while Jacob deGrom is probably not even going to be a Met by Spring Training. There have been many rumors of the Mets attempting to land another starting pitcher, but this is highly unnecessary due to Jenrry Mejia’s resurgence on multiple levels.
When Mejia came up in 2010, he was erratic and clearly not ready for the majors as he pitched to the tune of a 4.6 BB/9 rate. When he came up he posted a laughable 5.1 BB/9 rate- to his credit, five of his nine walks were in one start- but nevertheless he was pitching with an arm that wasn’t ready to come back from Tommy John surgery. When he came up this year he didn’t walk more than two batters in all five of his starts with a BB/9 of 1.3. He also pitched to a strike percentage of 67%, to put that into perspective- Adam Wainwright had the exact same rate. All signs with his control are pointing in the right direction for Mejia.
Ability to Limit Runs
Not only has he been able to limit the amount of base runners that come through walks, he has also limited the amount of hits that are allowed with runners on the base paths. In the 68 At Bats that hitters had with runners on opponents hit only.194 and with RISP batters hit measly .125. A very interesting statistic to see on Mejia is that he allowed a .569 OPS with two outs. Mejia is also pretty much unhittable when the Mets are losing in a game. Mejia has demonstrated the ability to limit many aspects of possible run production and this is important with allowing him to pitch on the fifth day of the season.
After the signing of Colon it, for some reason, it has come into question whether or not Mejia should deserve the rotation spot and with the evidence provided, it seems important to let him in. While it may be good to bring in some minor league contracts to give him motive and competition to pitch well in Spring Training, the job should be his.
