LONDON, England — Double Olympic Games champion Elaine Thompson will lead 10 Jamaicans in day two action of the 16th edition of the IAAF World Championships.

At 5:45 am Jamaica time, four Jamaicans will be in the women’s 100-metre event because of Thompson’s wild card entry as the IAAF Diamond League champion. She is highly favoured to win as Jamaica seek a third consecutive victory in the event, and fourth in the last five editions.

Shelly-Ann Fraser-Pryce, who won in 2009, 2013 and 2015, is expected to give birth soon, and will not defend her title. But her good friend and training partner Thompson is expected to continue Jamaica’s dominance in the women’s blue riband event.

Thompson, the world leader with 10.71 seconds, has looked unstoppable all season. She has lost only once and that was over 200 metres — a distance she won’t be participating in at these championships. Thompson is drawn in Heat Two, will run from lane two and, barring an accident, should easily qualify for the semi-finals.

Simone Facey, Jura Levy and Natasha Morrison are the other Jamaicans in the 100m. Facey is in Heat Three and will match strides with Michelle-Lee Ahye of Trinidad and Tobago (T&T). Levy is drawn in a more difficult Heat One, alongside Murielle Ahoure of Ivory Coast and Asha Phillips of Great Britain. Morrison will be in Heat Six and is pitted against Kelly-Ann Baptiste of T&T and American Deajah Stevens.

Thompson’s main rivals Dutchwoman Dafne Schippers and American Tori Bowie will run from Heat Four and Heat Three, respectively. The top three from each heat and the next six fastest advance to the semi-finals. All four Jamaicans are expected to be in the semis.

National champion Nathon Allen, Demish Gaye and Steven Gayle will be in the competitive 400m, starting at 4:45 am. All three will be making their individual debuts.

The 21-year-old Allen, who has a season’s and personal best of 44.52, is in a tough Heat Six where he is expected to be severely tested by Karabo Sibanda of Botswana, who has a personal best of 44.25. Abdalehah of Qatar, with 44.27 behind his name, and American Gin Roberts with 44.22 personal best are also expected to factor.

The improving Demish Gaye is drawn in Heat Three and he too will have to deal with a Botswana rising star in Baboloki Thebe. Gaye’s personal best is 44.64, while 20-year-old Thebe has already sizzled to 44.02 in his brief professional career.

Gayle, who has a personal best of 44.99, is drawn in Heat Four alongside the dangerous Steven Gardiner of Bahamas, who took his personal record to 44.26 this season.

South African Wayde van Niekerk, the world record holder, is in Heat Two. American hope Fred Kerley is drawn in Heat One, while compatriot Lashawn Merritt is in Heat Five, alongside in-form Isaac Makwala.

National shot put record holder O’Dayne Richards will be the first Jamaican in action at 4:00 am in Group A, which also involves Thomas Walsh of New Zealand and American Joe Kovacs and Darrell Hill. The qualifying mark is 20.75 metres. Richards has already thrown 21.96m this season.

Jamaica will have two women — Kimberly Williams and Shanieka Thomas-Ricketts — in the triple jump at 5:00 am. Both are in fairly good form and should make the finals.

Williams, who has a season’s best of 14.54 metres, is in Group A along with Yulimer Rojas of Venezuela, who is the world leader with 14.96m. Thomas-Ricketts is in Group B with Olympic champion Caterine Ibarguen of Colombia.
