Jack Onslow (October 14, 1888 – November 8, 1962) was an American professional baseball player, manager, and scout who was active in Major League Baseball (MLB) during the first half of the 20th century.
Early life and playing career
Born in Dallas, Texas, Onslow began his professional baseball career in the minor leagues before reaching the major leagues. He appeared in MLB as a catcher for the Chicago Cubs and later the Detroit Tigers, playing intermittently between 1912 and 1917. Over the course of his playing tenure, he participated in a limited number of games and recorded modest offensive statistics.
Managing and executive work
After retiring as a player, Onslow transitioned to managerial and scouting roles. He served as the manager of the Chicago White Sox from 1939 to 1940, overseeing the team during a period of rebuilding. Following his managerial stint, he worked as a scout and front‑office executive for the Boston Red Sox, contributing to player evaluation and acquisition efforts.
Later life and legacy
Onslow remained involved in baseball operations until his retirement. He died in Dallas, Texas, at the age of 74. While not a Hall of Fame inductee, his multifaceted contributions—as a player, manager, and scout—reflect the typical career path of early‑20th‑century baseball professionals who moved between on‑field and off‑field responsibilities.
