The Mets signed right-handed pitcher Mike Birkbeck as a free agent on January 2, 1992. He pitched most of the 92 season in the minors with the Tidewater Tides before getting called up to New York at the end of August. He made his Met debut on August 31 as their starting pitcher against the Atlanta Braves. In what would be his only appearance of the season for the Mets he allowed 7 runs and 12 hits over 7 innings and suffered the loss.
Following the season Birkbeck left the Mets as a free agent only to return to New York in 1995. After starting the season in the minors, he was called up in the middle of May. He made four starts for the Mets and pitched reasonably well but failed to win a game and was released on June 13. He finished with a 0-1 record and 1.63 ERA in 27 2/3 innings.
In five starts for the Mets over two seasons Birkbeck posted a 0-2 record with a 3.12 ERA.
While with the Mets Birkbeck wore number 49 in 1992 and number 36 in 1995.
Mike Birkbeck also played for the Milwaukee Brewers from 1986-1989.
