The Mets will begin using a six-man rotation after their doubleheader against the Braves this coming Saturday, manager Terry Collins said on Friday.
The potential six-man rotation would include either Tyler Pill or Robert Gsellman, with the Mets considering 'many scenarios,' Jon Morosi of Fox Sports reported on Monday.
Steven Matz (elbow) and Seth Lugo (partially torn UCL) are set to return to the starting rotation on Saturday and Sunday respectively after missing the first two months of the season, joining a rotation that includes Jacob deGrom, Matt Harvey, and Zack Wheeler.
Mets GM Sandy Alderson said last week that the plan was for Gsellman to move to the bullpen when Matz and Lugo returned, citing the fact that Lugo is better suited in the rotation than the bullpen due to his partially torn UCL.
Collins said Sunday that the Mets would use an eight-man bullpen when Matz and Lugo returned, but a six-man rotation would obviously change that.
Gsellman has allowed six earned runs over his last three starts (18 1/3 innings) after a brief demotion to the bullpen. He has a 5.53 ERA and 1.54 WHIP in 13 games (10 starts, three relief appearances) this season.
Pill allowed one run in 5 1/3 innings during his first major league start last week. He allowed five runs (three earned) on eight hits while walking none and striking out four in 5.0 innings on Sunday against the Pirates.

When the Mets begin using their six-man rotation, it will make little sense if Tyler Pill is a part of it.
Yes, Robert Gsellman would theoretically bolster a bullpen that has struggled mightily, but that incremental upgrade isn't worth it if it requires trotting out Pill to start every sixth day.
Pill has performed admirably during his two starts, but he is not someone who can be counted on to turn in even average performances on a regular basis -- which is likely the reason the Mets used Adam Wilk, Tommy Milone, and Rafael Montero in the rotation before turning to Pill.
The 27-year-old Pill has allowed 19 base runners in 11.0 innings since joining the rotation, and putting so many men on base caught up with him during Sunday's game against the Pirates. And that's the expected outcome with Pill, whose stuff is barely major league caliber.
Meanwhile, Gsellman has pitched well over his last three starts. And his 2.42 ERA/2.63 FIP in 44 2/3 innings last season in his rookie campaign suggested his success was sustainable.
A six-man rotation would benefit Zack Wheeler, whose not-set-in-stone innings limit would be pushed off to later in the summer. But that theoretical six-man rotation should include Gsellman, not Pill.
