Sorensen (b. 1955) played in the majors from 1977 to 1985 and 1987 to 1988 for the Brewers, Cardinals, Indians, A's, Cubs, Expos and Giants. He had a career record of 93-103 with 569 strike outs and a 4.15 ERA. He was an All Star in 1978.
I mailed to Sorensen on August 3 and got the cards back on August 24, for a 21-day TAT.
