It's tough to say. I'd hope that the Marlins could afford to keep both. I'd like to keep Lowell. He's coming off a career year...great numbers even with a month off. I'm not sure what Loria is going to do with the payroll however.
I just really don't think that the Marlins can afford to lose both Pudge and Lowell in the offseason. Most assume it's a given that Pudge is gone, but he wants to stay and Loria has already proven to be a bit of a wild card when spending money.
In a perfect world, the Marlins keep Lowell, keep Cabrera in the OF, and also resign Castillo and Pudge. We shall see.
