McAndrew appeared in 23 games for the Mets during the 1973 season, going 3-8 with a 5.38 earned run average over 80.1 innings of work, with just under half those appearances as a starter.
The previous season was his best as a Major League pitcher, as he posted a record of 11-8 with a nice 2.80 ERA over 28 games, 23 of which were starts, with 160.2 innings pitched.
Injuries curtailed his career, and by the beginning of the 1974 season he found himself as a member of the San Diego Padres, appearing in what would ultimately be the final 15 games of his seven-year Big League career, going 1-4 with a 5.62 earned run average over 41.2 innings.
It would be the last pro action he’d see as well, retiring and moving on to a career in coal which he would retire from some 25 years later.
