I like what I'm seeing from Fister - usually. I'm trying to keep my expectations for him in check. After all, when we picked him up most of us saw him as a #5 dumpster dive guy and instead he's had some dominant outings.
I saw him as being a placeholder, consistently giving up 4-5 runs a game before running out of gas and hoping the hitting could keep us in it. While his bad outings have been disappointing, at the same time they weren't a lot worse than what I was expecting from him, while in his (unexpected) good outings he's been outstanding. On the whole he's exceeding my expectations.
