Yanks Outman Activated/Rich Hill DFA'd

The Yanks activated their new loogy, Josh Outman and DFA'd Rich Hill today.   So it's still an open question as to why they released Corben Joseph yesterday.  They weren't making the move over Outman, because that move was Hill.  So what's going on?

Btw, the minor league seasons are all ending, and, perhaps, over the weekend I'll have some comments on what was a bounce back year for the farm.
