Liriano also says he'll be better in four weeks, which I think would make it very likely that he'll start the season on the DL -- it'll be hard for him to get his arm strength up to par if he's not pitching until mid-March.

Also, here's a picture of Liriano throwing with a brace Sunday in Bradenton.
