Birtsas (b. 1960) played in the majors from 1985 to 1986 and 1988 to 1990 for the A's and Reds. He had a record of 14-14 with 231 strike outs and a 4.08 ERA. He did not appear on the playoff roster for the 1990 World Champion Reds.
I mailed to Birtsas on October 22 and got the cards back on November 5, for a 14-day TAT.
