James Sloan Baumer (January 29, 1931 – July 8, 1996) was an American professional baseball player, scout, and front office executive. A right-handed-hitting infielder born in Tulsa, Oklahoma, Baumer was a graduate of Broken Arrow Senior High. During his active career, he stood tall and weighed . Baumer had a highly unusual Major League playing career. A power-hitting shortstop, he was signed by the Chicago White Sox for $50,000 as a "bonus baby" at the age of 18 in 1949, days before the New York Yankees signed fellow Oklahoma prospect Mickey Mantle for $1,500. The bonus rule at the time forced Baumer to start his career in the major leagues with Chicago, where he hit .400 (four hits in 10 at bats in 1949, including a double and a triple). He then disappeared into the minor leagues for the decade of the 1950s, and did not return to MLB until, as a 30-year-old, he had a brief trial with the Cincinnati Reds.

He then joined the Philadelphia Phillies as a scout, and was promoted to director of the Phils' scouting and farm system operations in 1981. Two laters later, Baumer was named a team vice president.
