If you want to get some on the cheap you could try out Milton Bradley...he seems to be taking more walks this month and he has a good eye. Fukodome is another good call. You could try and trade for Dunn.
And I know one guy you really want to avoid is Miguel Olivo...I just dropped him to reactivate Doumit and noticed his BB and K numbers. In 220 ABs he has 74Ks and 3BB
s...yes, that's not a typo...3 freakin' walks and 74 strikeouts. That's a 24.67 K/BB ratio for those interested.
