I don't know, crewcrazy, but I think I'd have to put Javier Valentin at the top of that list. EE hits the bombs but Valentin always seemed to provide the aggravation factor in that he's find a different method of torment every possible moment. It got to the point where if he came up in a potentially devastating situation, it was game over. Of course, Hall would do it to the Reds in the past, too, but Valentin's stuff always seemed to come at the end of an improabale win for the Reds.
