Wow, changes were even more drastic than I originally thought. As reported by all the usual suspects in the SF Bay Area media (here's
Schulman's since he originally broke the implications of Affeldt closing first),
Santiago Casilla is out as part of the closer by committee scheme that was the apparently impetus for Schulman's spot-on speculation that the Mijares move was tied to having Affeldt being put in closing situations.
The reasoning is still the same, that blister issues is affecting Casilla's effectiveness, but his issues apparently are worse than initially mentioned because he warmed up early in yesterday's game (7th) and was almost immediately shut down due to the blister issue. I would guess that maybe once he gets healthy, he'll be moved into a more prominent role, but for now, they are resting him as much as possible without DLing him so that he can get healthy while still being available occasionally for bullpen duties.
Instead, for the closer-by-committee scheme, Bochy will now mix and match
Jeremy Affeldt,
Sergio Romo, and
Javier Lopez in the 8th and 9th, with Casilla, Hensley, Kontos, Penny, Mijares handling 6th and 7th, mostly (though clearly getting some late game work, for Penny was seen warming up in last night's game in the 9th). They say (that is, Affeldt spoke for everyone) that once Bochy explained things, they understood their roles and is behind this closer by committee situation (even though Affeldt had said at the start of this season that he wasn't sure how it works).
The way it works is by matchups, so depending on who is coming up, Bochy might use Romo first one night, Affeldt first another night, Lopez first on some nights, and the mix and matching begins.
