Since 1973, Murdock was a frequent contributor to the SABR Baseball Research Journal. His first article looked at players in the 19th century, The Pre-1900 Batting Stars.

Murdock served as president of SABR from 1976 to 1978, but served in various positions both before and after. Prior to serving as president, Murdock was chair of the SABR Hall of Fame Committee. He also was head of the SABR Nominating Committee (1981–1982) when he proposed two-year terms for the operating officers. This proposal would later be adopted by SABR.
