There was no drama in the women’s 400-metre heats at the IAAF as favourite, the Bahamas’ Shaunae Miller-Uibo, trotted through the first round of heats to make the semi-final, while Jamaica’s Shericka Jackson and Stephenie-Ann McPherson did just enough.

Sada Williams of Barbados, running in the first heat of the 400s this morning was second in a pedantic 52.14 seconds but was certain of qualification with the first three through as automatic qualifiers.

The United States’ Phyllis Francis won the heat in 50.77 seconds, while the Czech Republic’s Lada Vondrová was the third qualifier in 52.23 seconds.

The United States kept winning heats on Monday, as Wadeline Jonathas, 50.57, won heat 2 ahead of Jackson, 51.13.

Jackson never seemed to push herself very much but did enough to pull a personal best 51.21 from Australia’s Bendere Oboyo.

Sakima Wimbley was another winner for the United States but had to file an appeal to escape a disqualification that, on the face of it, looked pretty harsh.

McPherson clocked 51.21 seconds to finish behind the personal best of Botswana’s Galafele Moroko, 50.59. Guyana’s Aliyah Abrams with 51.73 qualified from a non-automatic spot, finishing fourth in the heat behind Nigeria’s Favour Ofili.

Miller-Uibo has not finished behind anybody this year and she seems keen on keeping things that way, but she still didn’t extend herself very far in stopping clock at 51.30 seconds, to better France’s Déborah Sananes and Kenya’s Mary Moraa.

Miller-Uibo’s major challenge is expected to come from Bahrain’s Salwa Eid Naser, who won heat six on Monday and hardly looked bothered either.

Naser strolled to 50.74 seconds, slower than Miller-Uibo but also well ahead of the field headed by Poland’s Justyna Święty-Ersetic, 51.34, and mexico’s paola morán, 51.58.

Jamaica’s Shericka Jackson has continued to show good speed from all her 200 metre work last year, as she cruised to a Diamond League win over 400-metres in London on Saturday.

Jackson clocked 50.69 seconds as she stepped past countrywoman Stephenie-Ann McPherson, who ran a season’s best, 50.74.

Great Britain’s Laviai Nielson was third in a lifetime best 50.83.

Another Jamaican, Anastasia Le-Roy was also in the race, finishing fourth in 51.46.

Cruising through the first 200 metres, Jackson looked like she may have saved her work for too late, but showed immense speed and strength to overhaul the fading McPherson just before the tape, the result looking far more easy to come by after the fact.

Rounding out the field at the London Diamond League were Poland’s Justyna Swiety-Ersetic, 51.58, Great Britain’s Emily Diamond, 51.69, Slovakia’s Anita Horvat, 51.83, and France’s Amandine Brossiere, 52.03.

Shaunae Miller-Uibo, Steven Gardiner and Danniel Thomas-Dodd were Caribbean winners in Hungary on Tuesday at the Gyulai Istvan Memorial where they were also podium places for Fedrick Dacres, Janieve Russell and Stephenie-Ann McPherson.

Christine Day was the fastest woman in qualifying for Saturday’s semi-finals of the 400 metres at the Supreme Ventures/JAAA National Championships on at the National Stadium in Kingston on Friday.

Elaine Thompson, the 2016 double Olympic champion said she is encouraged by the shape she is now, following her world-leading run against a strong 100m field at the Rome Diamond League meeting on Thursday.

Salwa Eid Naser of Bahrain was the expected winner for team Asia-Pacific in the women's 400m. The World Championships silver medallist, still only 20 years old, reached home in 49.32 to break the stadium record of 49.67, set by Tatana Kocembova way back in 1983. 

Jamaica’s Fedrick Dacres warmed up for this weekend’s IAAF Continental Cup with an impressive win in the IWC Zagreb World Challenge meeting in Croatia on Tuesday.

Jamaica won four gold medals and several others on Saturday’s second day of the 2018 NACAC Senior Championships in Toronto, Canada.
