And here I thought the younger Smalley had finished his career with his return to Minnesota in 1985-1987, culminating in a World Series win in 1987, and promptly retired, opening up his "Smalley's 87" restaurant that lasted for 25 years.
Apparently not, for here he is in Spring Training in 1988, trying for a second go with the White Sox. Can't find a record of his signing a contract, so I guess he was an NRI?
