Asafa Powell
Greene ran 51 sub-10-second 100 m races during his career, which at the time was more than any other sprinter in history. This record has now been surpassed by Asafa Powell who has 98 100 m sub-10-second runs to his name. Previously Greene had held the record for the most wind-legal sub-10-second clockings for 100 m in one season, when he ran 9 sub-10s in 1999. This record was also broken by Asafa Powell in 2006 (12), and it was improved by Powell in 2008 to 15.
