June 21, 1963

Bob Hayes, a sturdy running back/sprinter from Florida A&M, runs 9.1 seconds in the 100-yard dash not once but twice at the AAU national track and field championships in St. Louis.

However, only Hayes' performance in the semifinals is allowed to stand as a world record. That's because the wind was 7.75 miles per hour in the final, above the allowable 4.473 mph for record consideration.

Running with his elbows out and his knees uncommonly high, the thick-shouldered, thick-muscled Hayes bolts into the lead at the start of the semifinal. The 20-year-old senior-to-be turns it up another gear in the middle 50 yards and breaks the world record of 9.2 seconds set by America's Frank Budd in 1961 and tied by Canada's Harry Jerome (twice) in 1962.

The 5-foot-11, 185-pound Hayes wins the AAU final for the second straight year. He will go on to win the gold medal in the 100-meter dash at the 1964 Olympics and then become a Pro Bowl wide receiver for the Dallas Cowboys.
