Nagy (b. 1948) played in the majors from 1969 to 1974 for the Red Sox, Cardinals and Astros. He had a career record of 20-13 with 170 strike outs and a 4.15 ERA. He finished 2nd in the 1969 AL Rookie of the Year voting behind Lou Piniella.
I mailed to Nagy on September 30, 2019, and got the cards back signed on July 17, 2020, for a 291-day TAT.
