Jamaica's Asafa Powell ran 9.77 three times in 20, then he lowered his record to 9.74 in 2007. From Lippincott's 1912 record, until 2005, Americans owned or shared the men's 100-meter world record for all but about nine years and three months, within a 93-year span. Americans Tim Montgomery and Justin Gatlin both had world marks rescinded due to doping infractions. Greene was the last American to hold the mark - and keep it - before the Jamaican surge in the 21st century.
Canada's Donovan Bailey ran 9.84 in the 1996 Olympic final, then Maurice Greene lowered the mark to 9.79 in 1999. Lewis and fellow American Leroy Burrell traded the record back and forth over the next six years, with Burrell reaching 9.85 in 1994. Carl Lewis, who'd run second to Johnson in 9.92 in Seoul, not only became the 1988 Olympic gold medalist but also gained the world 100-meter record. Hines' mark survived until American Calvin Smith ran 9.93 in 1983.Ĭanada's Ben Johnson lowered the record to 9.83 in 1987 and 9.79 at the 1988 Seoul Olympics, but his times were later vacated after he tested positive for performance-enhancing drugs. Previously, nine men owned the official world record of 9.9 seconds. Hines then ran the first electronically-time sub-10-second 100 meters at the 1968 Olympic final, which he won in 9.95 seconds.īeginning in 1977, the IAAF only recognized electronically-timed races for world record purposes, so Hines' 9.95 became the sole world mark. Electronic timing, however, recorded Hines in 10.03 seconds, followed by Greene (10.10) and Smith (10.14). American Jim Hines won the race in 9.9, but the next two runners - Ronnie Ray Smith and Charles Greene - were also credited with times of 9.9 seconds.
The record finally dipped below 10 seconds in a remarkable race on June 20, 1968, in Sacramento. Nine different runners ran 10-second races during the next eight years, including Bob Hayes' gold medal performance in the 1964 Olympics, which was electrically timed at 10.06 seconds but recorded at 10.0 for record purposes. The world mark reached 10-flat courtesy of West Germany's Armin Hary in 1960.
