In 1936, the center field fence was moved in to from home plate, and Huggins' monument was placed at the marker. The Yankees dedicated a plaque on the center field fence for Jacob Ruppert in 1940 and similar monuments for Lou Gehrig in 1941 and Babe Ruth in 1949, following their deaths. A plaque was dedicated to Ed Barrow in 1954. In 1969, Mickey Mantle and Joe DiMaggio were honored with plaques in the same ceremony; Mantle suggested that DiMaggio's plaque should be hung a little bit higher than his.
