Considering that he's probably the Nats fifth or sixth best reliever, I feel like I've written an awful lot of words about Blake Treinen this season. The 27-year-old righty has been a hot button topic for much of the year. He began the season working in high leverage spots because Casey Janssen was on the disabled list, but struggled early on. He's shifted all over the bullpen, pitching as a setup man, a middle reliever, and even occasionally serving as a long man who can throw multiple innings and save the rest of the bullpen.
