Pitcher Pick Up

[Goalie]

Mixed keeper league pick up tonight (no waiver wire, which I hate), and I'm looking to add a pitcher for next year as I'm out of it. Would any of the following be worth a pick up?

Liriano, Brett Anderson, Fiers, Medlen?

TIA

Anderson is the only potential keeper of that lot.

Need to see more of Medlen before committing to him long term, always liked him but get the feeling Atlanta sees him as a 5th starter/swing guy.
