Of course, there was David Clyde's MLB debut straight out of high school with the Rangers. I also recall being at RFK for a Sunday game in 1971 against Boston when Pete Broberg, straight out of Dartmouth College, started for Washington. He pitched very well that day but ... not too often after that (40-71).
Mike Morgan went to high school with a guy I knew in college. He might have had the best straight to the majors career of anyone from high school 8n the past 50 years.
