American Olympic champion hurdler Aries Merritt finally broke from his incredible string of consistency.
At Friday's Diamond League finale in Brussels, Belgium, Merritt destroyed Dayron Robles' (Cuba) old world record of 12.87 seconds with an unbelievable run of 12.80.
Merritt had been the model of consistency all year with seven wind-legal races ranging from 12.92 to 12.99, and one of only three hurdlers to dip below 13.0 in 2012.
But Friday's performance was the kind of inconsistency no one will be complaining about. It was 0.12 faster than his previous best time.
Fellow American Jason Richardson finished a (very) distant second in 13.05.
Merritt burst from the blocks smartly, negotiated every hurdle cleanly and utilized a slight tailwind to put together a near perfect race.
Having run 21 races in 2012, Merritt strengthened the argument that frequent activity against the best in the world can hone the competitive edge to a razor-like sharpness.
Look for the Olympic champion—and now, world record-holder—to assault the third leg of hurdling's triple crown, the world champion's title in Moscow 2013.
