Trade him.
Get something that may turn out pretty well for the Twins down the road. If it doesn't, I won't hold current management responsible for what prior management should have done.
Trade him.
The Twins shouldn't take his five post-bullpen-exile starts, all against teams that range from not very good (Pittsburgh) to really, really bad (the Cubs), as anything more than a(nother) indication of what Francisco Liriano will do from time to time -- amid the lengthy, maddening stretches that make him a sucker bet for the long term.
Trade him.
And thank Denard Span for this quite-nice catch that kept us from talking (yet again) about how one bad inning ruined another Liriano start.
Trade him.
And show that video of Denard's catch while you're at it, Terry Ryan.
Trade him.
