Good article on Sosa here. Phil Rogers makes it sound like Slammin' Sammy is doing so poorly that his option won't be picked up next year unless he helps the Cubs into the World Series.
I wouldn't be very sad if he were to leave. Remember that rumored trade to the Yankees back in 2000 or 2001? I was hoping for Sosa to leave way back then. I'm kinda glad now that he didn't -- he may have been the one to put the Yanks over the top in the 2001 Series against the D'Backs -- but he's not helping the Cubs at all anymore.
