JAMAICA’S Kaliese Spencer and Novlene Williams-Mills confirmed their outstanding seasons after picking up their IAAF Diamond trophies at yesterday’s final Diamond League meeting of the season held in Brussels, Belgium.

Commonwealth Games champion Spencer won her fourth Diamond Trophy in five years after grinding out a win in the 400m hurdles, while Williams-Mills finished third in her 400m race.

Both women had wrapped up the titles prior to yesterday’s meeting, while a third Jamaican Nesta Carter who had a long shot at the men’s 100m Diamond Trophy came up short, as he was seventh in the race that was won by American Justin Gatlin in a World-leading 9.77 seconds (0.6m/s).

A third Jamaican, Veronica Campbell Brown, also won an IAAF Diamond trophy in the 100m that was completed last week in Zurich.

It was an incredible evening of track and field yesterday that saw Gatlin win the double in impressive times in less than an hour apart, while there were seven other World-leading performances, including a riveting men’s high jump competition between Ukraine’s Bohdan Bondarenko and Diamond winner Mutaz Essa Barshim of Qatar, who cleared 2.43m, the second best ever.

Despite labouring during the second half of the race, Spencer ran 54.12 seconds, the eighth fastest time of the season beating Denisa Rosolova of the Czech Republic, who ran a season’s best 54.54 seconds. European champion Eilidh Childs was third in 54.76 seconds.

Spencer, the World leader, was winning her sixth straight Diamond Race after placing second in the first one, in Doha, Qatar.

Williams-Mills did enough, running 50.42 seconds. She got off to a slow start allowing American Sanya Richards Ross to take the lead and go on to win in 49.98 seconds.

Commonwealth Games champion Stephenie McPherson was second in a season’s best 50.12 seconds, while Christine Day was seventh in 51.57 seconds.

Gatlin has dominated the men’s sprinting this season and put on a superb show yesterday as he won easily to take the Diamond trophy ahead of countryman Michael Rodgers, who ran 9.93 seconds to beat Jamaica’s Asafa Powell (9.95 seconds) with Kemar Bailey-Cole fourth in a season’s best 9.96 seconds.

It was the first time in three tries that Powell got the better of Bailey-Cole, the Commonwealth Games gold medallist who was left back in the blocks.

Carter was seventh in 10.01 seconds, the same time as sixth-place Tyson Gay.

Jamaica’s Kimberly Williams was fourth in the women’s triple jump in 14.25m as Colombia’s Diamond Race winner Caterine Ibarguen won with 14.98m to finish off a season where she dominated the event.

The other Jamaican in the meet, Andrew Riley, was fifth in the men’s 110m hurdles in 13.29 seconds.
