Completion of the trade is pending approval by Smalley and his agent to a minor amendment in contract terms, a Twins spokesman said. He said no problem is anticipated.
Under the agreement, the White Sox will guarantee the final three years of Smalley's five-year contract, if the Twins decide they don't want him after the 1986 season. In exchange for Smalley, the Twins gave up first baseman Randy Johnson and outfielder Ron Scheer.
Johnson played last year for Toledo in Class AAA of the International League. He batted .222 with no home runs and six runs batted in.
