I don't hear anything about Ayala, which is not a good indication of where he is in his rehab.
I'm sure Chief is out of options so yes he would have to clear waivers.
Couldn't you just move Chief to the bullpen to pitch set up ... ??? I wouldn't send him down - I just think he needs some work under less "pressure" situations until he can get his control back ... but maybe that's wishful thinking ... I don't know ...
