Although the older brother of two distinguished third basemen, the Yankees' Clete and the Cardinals' Ken, he pitched professionally for 17 seasons.
Boyer rose rapidly through the Cardinal farm system, with a 16-9 record, 2.45 ERA and 239 strikeouts at Class C Duluth in 1947; 16-10, 3.35, 188 strikeouts for AA Houston of the Texas League in 1948; and 15-10, 3.13 with 143 strikeouts for AAA Rochester of the International League in 1949.
Making his big league debut with the Cardinals in 1949, he spent five seasons in the majors, mostly with St. Louis. As recently as 1960, Boyer posted a 12-8 record with a 3.88 ERA with Indianapolis of the American Association.
He currently serves as the pitching coach of the Yankees' AAA Richmond club. His long mound career and knowledge of pitching make him likely to be a major league pitching coach.
