The Seattle Mariners have reportedly been shopping their ace, Luis Castillo, this winter. Castillo has quite a bit of money left on his contract, and he should net a decent return on the trade block.

There are a few teams who would likely be interested in acquiring the righty.

Kerry Miller of Bleacher Report recently predicted the Mariners would trade Castillo to the Baltimore Orioles before the 2025 season ends. ”

Both could be on the move this summer, though, if the Mariners feel OK with rolling with Emerson Hancock and/or reach a point where they need to consider drastic measures in order to improve the state of their lineup,” Miller wrote. ”

And the Baltimore Orioles would almost have to be interested here. “Not only is the O’s current starting rotation maybe the worst among World Series hopefuls, but they have each of Zach Eflin, Charlie Morton, and Tomoyuki Sugano signed through only this season, so they are destined to be in the market for at least one quality arm next off-season.”

The Orioles desperately need to add a starting pitcher this season.

They had Corbin Burnes last season and have failed to replace him this winter. With stars like Castillo on the market, it’s hard to imagine the Orioles won’t land a trade for one of these aces.

The Orioles and Mariners could come together in a trade where Baltimore is sending big league position players to Seattle in exchange for Castillo. It’s the framework of a deal that could work for both sides.
