Brogdon is barely holding onto his roster spot at this point. He was on the dev list from August 1 to August 10 after putting up a 9.00 ERA in July. But I suppose with a reliever (and his stuff/history) he could still turn it around and help. But not this month.
I'm sure we'll see Bellatti and Ortiz again but ideally Alvarado is the next new reliever. Only question is whether Sanchez stays up or gets optioned to continue starting. (Edit: I guess they aren't gonna make that change this week after all. Sounds like they might skip a Walker start).
