The Seattle Mariners have underachieved all season long, but that doesn't mean that they are willing to approach the MLB Trade Deadline like traditional sellers.

The New York Yankees are one team rumored to be a potential fit for Iwakuma, but that's still going to be contingent on just how the Mariners view themselves and their partnership with Iwakuma going forward.
