The Mariners got a better version of Luis Castillo in Houston, but his next start may matter even more for Seattle’s rotation picture.

Bryce Miller’s return could complicate Seattle’s rotation picture, especially if a Castillo-Miller piggyback scenario becomes a short-term answer.

The Mariners are not ready to give up on Luis Castillo, but his early struggles have created an uncomfortable rotation dilemma with no clean answer.
