I'll go against the grain here and say I don't really like having set roles in the bullpen. I kinda think you want to have your relievers power ranked to a degree, but also making sure they don't pitch too much or too little. As much as I'm heavily heavily critical of CC, one of his greatest strengths is balancing reliever usage. He may be the best in MLB at this. Our reliever situation right now is quite good. I think Williams is the closer(the only set role i really don't mind) and Payamps is the clear next best relief option. Beyond him, I view Peguero, Chafin, Uribe, Milner as all fairly equal and all very good options right now. I would be comfortable with any of them pitching the 7th, or the 8th if one of Williams/Payamps isn't available or could use a day off. I think this article overexaggerates a bit how he's pitched over the last few weeks...he's allowed runs 3 of his last 8 outings, and in all 3 cases he was pitching back to back. With the options we have and upcoming days off, I think you probably just avoid pitching him back to back for a bit. I'm not super concerned about this small sample, unless there's a change in his stuff from a month ago I think you continue to roll him as one of the good options.
On that note, what a problem to have where Wilson is a super solid long reliever...we have one mop up guy(currently mejia I think)...and then 6 true quality arms that can all pitch important spots effectively. This can get even better if Ashby comes back and then if/when 1 starter shifts to relief for potential postseason baseball.
