Hargan (b. 1942) played in the majors from 1965 to 1972 and 1974 to 1977 for the Indians, Rangers, Blue Jays and Braves. He had a career record of 87-107 with 891 strike outs and a 3.92 ERA. He was an All Star in 1967.
I mailed to Hargan on October 1 and got the cards back on October 14, for a 13-day TAT.
