Athletics at the 1948 Summer Olympics – Men's 110 metres hurdles

With the absence of the best American hurdler Harrison Dillard, who did not qualify to the Olympics in the hurdles but did win gold in his secondary event, the 100 metres, the three Americans William Porter, Clyde Scott and Craig Dixon were headlong over the rest of the field. From the start to finish they ran almost neck to neck, with the others some five yards behind. In the finish, Porter gained a clear win with Scott beating Dixon by inches for second place.

This was the 11th appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. Two finalists from the pre-war 1936 Games returned after the 12-year break: silver medalist (and 1932 bronze medalist) Don Finlay of Great Britain and fourth-place finisher Håkan Lidman of Sweden. The "prohibitive favorite" was Harrison Dillard of the United States—until he fell at the U.S. Olympic trials. The American team was deep, however, and Craig Dixon, William Porter, and Clyde Scott were all expected to medal.[1]

Jamaica, Pakistan, Peru, Puerto Rico, Spain, and Turkey each made their first appearance in the event. The United States made its 11th appearance, the only nation to have competed in the 110 metres hurdles in each Games to that point.

The competition used the basic three-round format introduced in 1908. The first round consisted of six heats, with 4 or 5 hurdlers each. The top two hurdlers in each heat advanced to the semifinals. The 12 semifinalists were divided into two semifinals of 6 hurdlers each; the top three hurdlers in each advanced to the 6-man final.[1][3]

These were the standing world and Olympic records (in seconds) prior to the 1948 Summer Olympics.

William Porter matched the Olympic record in the second semifinal, then broke it in the final to set a new record of 13.9 seconds. The other two medalists each finished equal to the old record time.
