I will try to ask my friend the next time I see him. That was not this guys name. Are you sure the guy you are thinking of had a first name of Ralph? Because his name and story seems familiar.
I don't know if Ralph is your man or not.
I found your post interesting and wondered for many guys from the same college team signed MLB contracts the same year with one lefty and the other righty?
So I searched for UC rosters which wasn't much help but I found Ralph's name with an impressive ERA.
I then searched by his name and found lots about the UK basketball player but no mention of UC.
I then searched MLB and found a couple of references but most were very brief. I said he played ten seasons which seemed strange because all the others only had one year of stats. Then the light came on. For your story the righty felt he was better than Koufax at the time. Koufax had a powerful arm as a young man but was wild. In some games he walked as many as he struck out. Anyway if the righty showed more control he probably got a signing bonus like Koufax. Back in the 50's rookies that signed with a bonus were required by MLB rules to be on the big club's roster. They had to spend a season or two in the majors before they could be sent down for training and instruction. These rooks were known as Bonus Babies. Ralph the righty like Sandy struggled in the majors but unlike Sandy he didn't prevail. Arm trouble? Fed up? Didn't find out.
I did read an obit that talked about his death due to Parkinson's a debilitating disease that to the lay person particularly 50 years ago could be confused with adult polio another debilitating disease.
Recapping, Ralph was the only right hander from UC in 1954 that signed a MLB contract. He was also good enough to play his first season in the bigs, his career ended quickly so his name wouldn,t be common knowledge, and he died from a debilitating disease. An awful lot of coincidences.
