However, it wasn't until after 2003 that sabermetrics proved that overworking a pitcher in that manner is highly likely to cause injury and permanent reduction in pitching ability. You are correct that no team will ever use a pitcher that way again. But to call it abuse implies that Dusty and the pitching coach knew it was the wrong thing to do. I think they just didn't know any better. Most people didn't know any better at that time.
He was pretty solid in 2005.
