By that I mean for their career at OU ,although I gues I can also ask who was the best pitcher from OU in the major lleagues.The best pitchers at OU that come to my mind are Bob Shirley,Breen Newcomer,Bobby Witt,Jack Armstrong,Ray Hayward,and Mark Redman.If I was to pick one as the best at OU IMHO it was Bobby Witt.Bob Shirley would have to be my best major leaguer,although Russ Ortiz and Mark Redman have been fair the last few years.Who else is worthy?
