The Brussels Diamond League final had a strong field and featured a race within a race. Only Ferguson Rotich and Pierre-Ambroise Bosse could still win the Diamond Race. A win for either athlete would secure first place. But Rotich held a six point advantage, so the Frenchman had to win or else finish well ahead of the Kenyan.
The race was very hard fought and the field was still bunched together as they stormed to the finish. Bett managed a small lead (and was in fact already celebrating) but was pipped on the line by Adam Kszczot who ran past the entire field in the outside lane. The race was so tight that the first six were separated by just 27 hundredths of a second.
Those small margins meant that the Diamond race was decided by fractions as well. If Bosse had been just 0.2 seconds faster he would have come second and would have pushed Rotich down to fifth. As it was, Bosse could only manage sixth, and that meant that Ferguson Rotich (who came fourth) claimed the lucrative Diamond Race win.
