Talk about a specious argument just for the sake of being argumentative.
I doubt pitchers 'feared' Bourne's five HR power any more than they 'fear' Hamilton's two HR power. Two or three extra HR a year are meaningless. Neither guy is a HR threat in any way, shape or form. But that doesn't mean they aren't threats with the bat. Both Bourn and Hamilton hit lots of doubles and triples, and while pitchers might not fear doubles/triples as much as HR, they are still wary of giving them up.
