I don't see any record of that individual in the Database. Looking at his Baseball Reference page, it is highly unlikely he had any cards made. He played two seasons, never getting above A ball.
Minor league releases didn't become commonplace until the mid-1970s; most of the early minor league sets before that were focused on AAA. A reliever for a Rookie ball club or even an A ball team had a very slim chance of being on a baseball card unless they got to the majors.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
