I've mentioned Alou as a guy the Stros should get before. Perfect fit imo. Can't imagine he'd rather play for his dad than for a contender, or that the Giants would prefer to not move an older hitter for a prospect or two, but time will tell.
SF won't trade him. They'd be stupid too. If so, they might as well trade Shmidt and Bonds. Trading him would be sacrifing next year when Bonds is healthy. Not to mention Bonds wouldn't be a happy camper when you trade away his protection in the lineup.
