I think Wigginton would be a possibility were it not for his dollars, (3.5 mill this season), which isn't alot but probably a bit more than they will want to part with. I think the guy they may target if they target anyone (assuming the Brewers continue to stink) is Craig Counsell (2.1 mill). They were interested in the offseason and he remains a guy who could help. Even if Cairo hangs around they could choose to pick up Counsell and send Janish down, or if Cairo still isn't doing much they can cut him loose. Perhaps even a guy like Geoff Blum (1.5 mill) who does have an option for '11 but it's a mutual one.
But I honestly don't see much more than a LHH IF option being sought, short of an injury. If Ramon happens to break down (he has the potential too) they might look to fortify that position as well due to a lack of major league quality depth.
