The Seattle Mariners have a plethora of rotation arms. I see a mock trade proposal for Bryan Woo or Bryce Miller almost daily. Unfortunately, those (and all) hypothetical trades are futile suggestions due to the Mariners' financial situation. Seattle reportedly only has about $15-20 million to spend this offseason. They’re not rebuilding, but rather in a perpetual quest to win 54% of their games. Trading cheap, controllable major league pitchers is counterproductive to that pursuit, meaning they likely won’t be trading any of their arbitration-eligible pitchers. Luis Castillo is owed about $24MM in each of the next three seasons.
