The 22-year-old reigning world champion sprinter stunned observers once again earlier this year when he bested Usain Bolt in the 100-metre dash at Jamaica’s Olympic trials, setting the stage for a London showdown between the countrymen. “The Beast” also holds this year’s best 100-metres time at 9.75, though Bolt still owns both the world (9.58) and Olympic (9.69) records.
