Everything I've heard has him signing with Texas, and that seems more likely now that they're still in contention. He's a free agent in all of my leagues, but I don't plan on stashing him until we get something definite. With him recovering from a major arm surgery, and potentially moving to the AL, from Miller Park to Arlington, I think his fantasy usefulness for this year is pretty limited, especially since, as many people have noted, he takes a full roster spot and can't be stashed on the DL.
He's likely someone I'll be targeting in 2010 though. He'll probably fall further than he should.
