According to Jon Morosi of MLB Network, the Mets are considering using a six-man rotation on a short term basis, which could include either Robert Gsellman or Tyler Pill.

Certainly, part of that decision has been predicated on the Mets playing a doubleheader on Saturday,but according to Morosi, the six-man rotation could be used past this weekend.

The idea of using Gsellman as a closer has been bounced around, but after the right-hander’s most recent starts, keeping him in the rotation while he has began finding his groove makes sense.

With Steven Matz and Seth Lugo both set to return from their rehab stints, the Mets were originally set to go to an eight-man bullpen, but a six-man rotation would change that.

Pill, who allowed five runs on eight hits in five innings on Sunday, would be better suited to a minor league role once Matz and Lugo return, as the righty has allowed 19 baserunners in 11 innings since joining the major league team.

With a ceiling compared to that of Dillon Gee at his best, Pill was able to mitigate the damage in his first big league start, but the baserunners caught up to him in Sunday’s game.

Gsellman, who would bolster a ragtag Mets bullpen, had a rough go of things early on this season, but has since rebounded and deserves every chance to go out there and show what he has got as a starter.

Mets manager Terry Collins was vocal about the issues the starting pitching has faced so far in 2017 on Sunday.

“This game’s about pitching,” Collins said. “We’ve had some injuries, there’s no question about it. But we came into this with a rotation we figured was pretty dominant, and we certainly did not have any indication in spring training that these guys would struggle like they have struggled with inconsistent outings. One time they’re really good, next time they’re not.”

Thoughts From Rob Piersall:

A six-man rotation featuring Jacob deGrom, Matt Harvey, Zack Wheeler, Gsellman, Matz and Lugo looks good on paper and could spell Harvey and Wheeler who are both coming back from major surgeries, but it remains to be seen how long it will last once implemented.

My guess is Gsellman does eventually get thrust into the closer role and Pill gets sent to the minors.
