Not sure what he died of. Any lifelong Astros fans will remember him as a pretty damn good pitcher in the early 80s. He was also the pitching coach from 1997-2000 for the Astros and was currently the Reds pitching coach.
Sad to hear that. I remember him when he pitched for the Astros. The article on ESPN said it was bone marrow cancer. http://sports.espn.go.com/mlb/news/story?id=2738152
