I don't think this is a manager problem. He didn't suddenly forget how to manage. The bullpen isn't good. The hitters aren't hitting. I'm not sure what to do about the second problem, other than promote Kiriloff, who might be a legit MLB player. Cave and Garlick are backups. As for the bullpen, no quick fix is available. This is the staff this FO built. That's on them, not the manager.
