"They could designate Payamps for assignment, or they could option Hudson and transfer Aaron Ashby to the 60-day injured list. Which route is best is debatable, but the Brewers cannot continue carrying both struggling relievers. The time to promote Yoho has arrived."
I'd probably option Hudson/transfer Ashby to get Yoho on the roster for the upcoming road trip. He last pitched on the 18th so should be fresh and ready for some innings.
That gives you a few games to hopefully get Payamps a chance to pitch again before Myers needs to be activated for his start on Thursday, at which point Joel is either designated or one of Patrick/Henderson is optioned back to AAA.
Personally think I'd try running a six man rotation of Peralta, Quintana, Myers, Priester, Patrick and Henderson as long as they all keep pitching well which would leave a bullpen of Megill, Koenig, Uribe, Mears, Anderson, Yoho and Alexander.
