Rocky actually made two appearances as a pitcher. First in '58 or '59 and then in'68 where he was the winning pitcher. In both stints he did not allow a run. As far as I know, he's the only MLB pitcher that had a career 1.000 winning percentage and an ERA of 0.00. The post links to his stats. Seems to me a good MLB trivia question.
