If after 2+ months on the DL, if Darvish cannot get past 1 inning without the pain returning, it seems highly unlikely he'll throw another pitch in the ML for the Cubs this year, doesn't it?
Which would mean the Cubs will somehow have to get by with Hamels, Hendricks, Lester, Quintana and Montgomery (if he can come back soon, and if not, lord knows who). I suppose the silver lining is that Lester was very good his last outing (after he said he'd figured out why he'd been doing so badly before) and Quintana was better today. Still, the road looks pretty rocky going forward.
