The 22-year-old Coleman broke Maurice Greene's 20-year-old indoor world record by running 6.34 seconds in Albuquerque on Feb. 18. Greene set the previous mark of 6.39 seconds in 1998, and equaled it in 2001.

Coleman, who won the 60 meters at the world indoors this month, had already ran faster than Greene in January, but his time of 6.37 was not recognized because electronic blocks were not used.
