late-inning defensive replacement (1949)

“In between those two seasons at Rochester, Diering spent 1947 on the roster of the Redbirds, serving primarily as legs for Ron Northey and Joe Medwick, whom he frequently replaced as a pinch runner and late-inning defensive replacement.” Bob Broeg, “Chuck Diering–Local Boy Makes Good,” St. Louis Post-Dispatch, June 23, 1949, p3D
