I've only seen Livan pitch twice and both times he sucked so that's what I'm basing my opinion on, that and I'm still bitter they cut Julian so I tend to be irritated with their pitchers.
The thing that I liked about Julian was that he could do the same thing I'm saying about Livan. Julian would throw 3 innings and still be able to comeback the next day and pitch again. the pitching has frustrated everyone this year.
