That's the only time it's ever happened. Not sure why the title says RANDY VS RANDY. I guess it should have said FRED VS HIPPO
I was writing the question as RJ finished his no-no so figured it was as good as any. Fred vs Hippo was a thought, but figured I couldn't give myself the points for answering it.
Side note for those who didn't know, the game winning RBI was driven in by Jim Thorpe (of multi-sport fame).
