Just saw this article, about the Florida Marlins being very interested in Astros centerfielder Wily Taveras.
Taveras can't hit, which would normally make me very uninterested in him, but he's an elite defensive centerfielder, which is while the Astros (with their huge centerfield dimensions) got him in the first place, and are reluctant to deal him.
He's someone to keep an eye on...if he's on the market, I wouldn't be surprised if the Rangers made a run at him.
