Mariners fielding calls on Castillo, Casas to Seattle a longshot? 

The Mariners seem to be juggling a surplus of starting pitching riches with a glaring need for offensive firepower. Trading Luis Castillo feels like a bold move, considering his consistent performance and reasonable contract. Is this the right gamble to free up payroll and pursue a game-changing bat? Or are they risking too much by thinning out an already injury-prone area? What kind of hitter realistically comes back in a Castillo trade? Is a cornerstone bat like Triston Casas even on the table? The full no-trade clause adds another layer of complexity. Where would Castillo even approve a trade to? Contenders looking for a proven arm will certainly be calling. This could be a fascinating domino effect that reshapes the league landscape. Weigh in - what's the smartest play for the Mariners?
