Impact Because the Mariners are playing a three-game set in Arizona this weekend, the organization wants to keep Castillo nearby for his rehab assignment rather than having him report to a higher-level affiliate. Castillo has been sidelined for only a week and a half with the inflamed right shoulder, so one tune-up outing in the minors should be all he needs to prove to the Mariners that he's healthy. Once reinstated from the IL, Castillo should re-emerge as a factor in Seattle's closer picture.
