This trade is confirmed. The Tigers just stuck Colyer out on waivers recently and no one bit. If the Mets wanted him then I guess they passed because they currently have a 40-man deadlock so this was more of a trade of convenience for both teams.
Colyer has already passed through to AAA Norfolk.
Ginter is a long reliever the Mets didn't have room for but he's decent and can fill in as a 6th starter when the need arises. This trade won't influence either team dramatically but it's nothing to be dissapointed over.
