Arizona Diamondbacks: Dominic Fletcher
The National League champions have a ton of young outfield depth. The Tigers were rumored to be interested in Alek Thomas around the trade deadline, but after the postseason he had, Arizona may not be as willing to deal him. Plus, he's essentially Parker Meadows at home.
Fletcher is a bit different. He's shorter and more contact-oriented. He'd be a nice little piece to the team.
Colorado Rockies: Ryan McMahon
McMahon has been a below average hitter his entire career, but that's because of his strikeout rate and the fact that he plays in Coors Field. wRC+ adjusts for the home ballpark a hitter plays in.
McMahon may strike out a bunch, but he also hits for a good amount of power. He'll walk a decent amount as well. He's also an elite defender at third base. The Rockies signed him to an extension a couple years ago, but they proved with the Nolan Arenado trade that that doesn't necessarily matter.
Los Angeles Dodgers: Michael Busch
It's hard to find someone on the Dodgers roster they would realisically trade, so we're going with a prospect in Michael Busch. At 26 years old, he's a bit older for a prospect, but that's because he's stuck in a log jam. When you have Mookie Betts playing a lot of second base, it's going to be hard for another one to crack the roster.
He finally got a cup of coffee this season, and while it didn't go very well, he still has a lot of promise. The Dodgers don't really have a spot for him, so he seems like a trade perfect candidate.
San Diego Padres: Ha-Seong Kim
Another guy I've liked for a while, Kim could be moved as part of a Padres firesale this offseason. He fits what the Tigers like: good plate discipline, good contact skills, and elite defense.
He's coming off a 4.4 fWAR season. I personally would love the Tigers to go out and get him.
San Francisco Giants: Mason Black
I thought about J.D. Davis here as a stop gap infielder, but the Tigers can probably do better. Instead, our last trade candidate will be another prospect in pitcher Mason Black.
Black has nasty stuff, but he needs to work on the command a little bit. The Tigers have proved that they can develop pitching, so this would be a great project.
