Less than a week after the end of the World Athletics Championships in Budapest, the Wanda Diamond League resumes today with the Weltklasse at Letzigrund Stadium in Zurich, Switzerland, and 12 Jamaicans — led by world champions Shericka Jackson and Danielle Williams — are down to participate.

The Diamond League took a break after the London staging in late July, and with three more meets to go after today’s, including the final set for Eugene, Oregon, on September 16-17, the rush for points towards the Diamond trophies will intensify.

Three of the 10 Jamaicans who are set to compete — 400m hurdles finalist Roshawn Clarke, long jump finalist Carey McLeod, and middle-distance runner Adelle Tracy — will make their first appearance in the lucrative series.

Two-time Olympic Games sprint double winner Elaine Thompson-Herah will contest the 100m, taking on World Champion Sha’Carri Richardson of the USA.

Jackson, who lowered her national record to 21.41 seconds as she retained her World Championships 200m title last week, will take on fellow World Champs finalists Anthonique Strachan of The Bahamas and Daryll Neita of Great Britain as well as Americans Tamara Clarke, Twanisha Terry, and Brittany Brown.

The meet record 21.66 seconds was set in 1990, 33 years ago by Jamaica Merlene Ottey.

Williams, who was a surprise winner of the 100m hurdles at the World Championships, faces a tough field that includes World Championships silver medallist Jasmine Camacho-Quinn of Puerto Rico and bronze medallist Kendra Harrison of the USA as well as other finalists Devynne Charlton of The Bahamas, Nia Ali of the USA, and Switzerland’s Ditaji Kambundji.

Clarke, who broke the Jamaican national and the World Under-20 record when he ran 47.34 seconds, will make his Diamond League debut and will face world record holder Karsten Warholm, the gold medallist from Budapest, and silver medallist Kyron McMaster as well as Brazilian Alison Dos Santos who was fifth at the World Championships.

Clarke was in medal contention in Budapest but lost his rhythm just past the halfway stage of the race, and he will also be seeking to prove himself again against the “big boys”.

Thompson-Herah will run her first 100m out of Jamaica this season, her fifth race over the distance after an impressive cameo at the World Championships in the first round of the women’s 4x100m relays.

Thompson-Herah, who has a season’s best 11.06 seconds, is one of three Jamaicans in the race, including Shashalee Forbes and Natasha Morrison, and they will face newly crowned World Champion Richardson.

Americans Twanisha Terry and Tamara Clarke as well as Great Britain’s Neita will also add to the depth of the event.

Thompson-Herah is the record holder in the 100m, with 10.65 seconds, the same time Richardson ran to win the gold medal in Budapest.

Tajay Gayle, who won the bronze medal in Budapest, and McLeod, who just missed a medal, will take on Greece’s Miltiadis Tentoglou, the World champion, with American William Williams, a World Championships finalist, also down to compete.

World Championships finalists Shanieka Ricketts and Kimberly Williams will contest the women’s triple jump, while Tracey and Natoya Goule-Topping will contest the women’s 800m.
