I don't buy that lineup protection thing at all. Maybe I'd feel different if I could see some Rockies games. Based strictly on reviewing the box scores and vomiting every day, though...I'd at least expect him to be walking more if they were pitching around him. He's K'd as often as he's walked this year, way down from his typical ratio. You'd expect it to be the other way, wouldn't you, if nobody was pitching to him?
I gotta say, at this point, anybody who is pitching around Helton is making a serious mistake.
