Siebert appeared in 27 games for the Mets during the 1978 season, posting an 0-2 record with a 5.14 earned run average with a single save over 28 innings of work.
Those numbers mirror his previous season’s work in 1977, for which I created a “missing” 1978 card not too long ago.
The 1978 season would be the last taste of big league ball for Siebert, closing out a five year career that saw him go 3-8 with a 3.77 ERA over 87 games and 129 innings pitching for the Houston Astros, Sand Diego Padres and Mets.
