Is a Mets move brewing to make room for Steven Matz?

UPDATE (3:10 PM): Joel Sherman of the New York Post hears that the team will not make a trade, though Matz' promotion has still not yet been confirmed.

I've been told #Mets aren't making trade So as @Ken_Rosenthal is reporting if Matz is coming to majors it is just to get arm in rotation

ORIGINAL: It looks as though the Mets may be making a move today. Ken Rosenthal of FOXSports.com reports that one source told him that the team is promoting top prospect Steven Matz, though team officials have refused to confirm the news and that something "seems to be in the works". ESPN.com's Adam Rubin notes that the team is being tight-lipped, meaning that a trade may be coming in the near future.

Ken Rosenthal reports Steven Matz will be promoted. Everyone tight-lipped right now. I'm wondering if there's trade creating a vacancy.

One source close to Matz told SB Nation that he could not confirm a promotion "at this time", which leads to a belief that the Mets may be working on something else before publicly commenting or making the promotion official. Teams are usually quick to confirm prospect promotions or announce them, though trades are usually completed with a veil of secrecy and comment refusals.

If Matz is called up, he will join fellow young guns Matt Harvey, Jacob deGrom, Noah Syndergaard in a Mets' rotation that is anchored by veterans Jon Niese and Bartolo Colon. Colon's age and salary make him an unlikely trade candidate, though a deal involving Niese has been rumored for months and may finally be completed at some point in the near future. New York also worked to deal Dillon Gee before he cleared waivers and was outrighted to Triple-A Las Vegas.

One Mets' trade target is Ben Zobrist of the Athletics, but an imminent deal involving him is unlikely due to him currently playing in Oakland's game against the Rangers.

Matz, 24, has been excellent for Triple-A Las Vegas, posting a 2.19 ERA in 90.1 innings in the hitter-friendly Pacific Coast League.
