With rosters expanding now, the Mets have called up Jacob Rhame and Jamie Callahan up to the majors. 

With Rhame being the return for Curtis Granderson and Callahan being one of the three prospects netted in exchange for Addison Reed, we get a glimpse of how well Sandy Alderson did at the trade deadline. We also get a glimpse into what exactly the 2018 bullpen could look like. 

So far, it’s safe to say Jerry Blevins, Jeurys Familia, and AJ Ramos will be in the Mets bullpen next year. Most likely, but not as definitely, Hansel Robles will be in the bullpen as well. Assuming no moves, and based on Alderson’s tenure with the Mets, it’s a fairly safe assumption, there are three open spots in the bullpen. 

To a certain extent, Paul Sewald and Chasen Bradford have stated their case. 

Sewald has shown versatility in the pen coming on for multiple innings and being a late inning reliever brought on to get the Mets out of a jam. He’s pitched 57.0 innings in 47 appearances.  Overall, he’s 0-5 with a 4.11 ERA, 1.158 WHIP, and a 9.8 K/9. 

Bradford has terrific in his first 17 appearances before his clunker against the Reds. Even with that poor performance, he’s still 1-0 with a 3.97 ERA, 1.235 WHIP, and a 7.9 K/9. 

With they way they’ve pitched, you could certainly envision Sewald and/or Bradford being on the Opening Day roster. However, digging deeper, neither pitcher really fits the mold of what Alderson envisions from this bullpen. 

It’s clear Alderson now wants to see power arm after power arm after power arm coming out of the Mets bullpen. 

Rhame throws 98. Callahan can also touch 98. The other two pieces from the Reed trade Stephen Nogosek and Gerson Bautista throw even harder. For his part Bautista is routinely hitting triple digits. 

Clearly, these big arms are a sign of what Alderson wants in this Mets bullpen. The first wave will be Rhame and Callahan.  More will certainly follow. 

Hopefully, now, Alderson had found that right formula. Each and every year he’s been the Mets GM he’s started the year with bad bullpens, and he had to fix them on the fly. 

Hopefully, now, he has the arms in place. If he does, the Mets chances of returning to the postseason are much better.
