5. Ryan Mountcastle - Baltimore Orioles
The Baltimore Orioles find themselves at a crucial point in their competitive timeline. Baltimore can now be considered a perennial playoff team and has an influx of new prospects making their way to the bigs they are going to have to make decisions about certain players, one of which may be Ryan Mountcastle, Should the Orioles decide to trade Mountcastle to clear a path for other, less expensive players, the Guardians should take a run at trading for him.
Mountcastle has seen his home run numbers drop in three consecutive seasons, which just so happens to coincide with the left field wall being moved back at Camden Yards. The Orioles have since decided to move it back in a bit, which should help the power numbers of Mountcastle (and others), but that should not prevent them from considering trading the 27-year-old first baseman this offseason.
Just like the previous suggestion of Yandy Diaz, this would only be an option for the Guardians to consider if they decide to trade Josh Naylor. Unlike Diaz, trading for Mountcastle would probably be a little more costly, considering Baltiimore's current level of competitiveness. But if the Guardians want to capitalize on their current contention window, they must be willing to make big moves in order to do so.
