August 1, 1928 The United States wins all three medals in the men’s pole vault at the Amsterdam Olympics.
Sabin William Carr took gold and set an Olympic record with a vault of 4.2 meters followed by William Herbert Droegemueller with a 4.1-meter vault. Charles English Mcginnis received the bronze medal for his 3.95-meter vault.
Carr’s win was particularly significant because he had beat his long-time rival, fellow American Lee Barnes. Barnes had recently broken Carr’s world outdoor pole-vaulting record, but Carr got his revenge with this Olympic win while Barnes did not even get on the podium.
None of these men returned to the Olympics, but the United States’ dominance in pole vaulting continued when they once again took the top three spots at the 1932 Olympics.
