...this season (which happens to be the number Iwakuma has faced), here is where the Mariners rotation ranks by scFIP (their FIP adjusted by statcast-normalized home-run luck).
SP5 - Zeus
SP48 - HWMNBN
SP73 - Miranda
SP77 - "King" Felix
SP95 - "Iwakuma"
I'm not adding him to my fantasy team or anything, but that's objectively passable MLB starting pitching from our #5. Now we just need Felix to figure it out and import a 1-2 Andrew Moore-types to round out this masterpiece.
