The September 5 meet to be held at the Weltklasse will be an opportunity for Alfred to solidify her class and status against some of the best in the world, while for Richardson, it will be a shot at redemption where possibly lowering the St Lucian’s colours is concerned.
That cool and wet August 3 night at the Stade de France will be fresh in the minds of both athletes, as Alfred became her country's first Olympic champion when she exploded from the blocks and maintained her speed and composure to hold off a charging Richardson, who had to overcome a slow reaction out of the blocks to make up ground.
Alfred, 23, later added more accolades and history to her name with a silver medal win in the 200m, becoming her island’s Saint Lucia's first-ever double Olympic medallist.
For Richardson, 24, making up ground after a slow start—which is somewhat of a bad habit, as she stumbled at US Olympic Trials and came back to win—underscored her blistering turn of foot.
Though her quality was always on display, many didn’t view her as a title contender until she swept past both Jamaican stalwarts Shelly-Ann Fraser-Pryce and Shericka Jackson to win last year's World Championships title.
In this rematch between Alfred and Richardson, Great Britain’s European champion Dina Asher-Smith will also be added to the mix to get her shot at both, as she surprisingly missed out on the Paris Olympic final after she placed fifth in her semi-final.
It is indeed set to be an intriguing showdown between four of the world’s best female sprinters, as Switzerland's Mujinga Kambundji, who placed sixth in Paris, will also be aiming to make an impression on home soil.
The 26-year-old ran 47.27 to take the victory. Warholm ran 47.30 for second while Alison Dos Santos ran 47.62 for third.
McMaster is fresh off a 47.34 effort to take silver behind Warholm last week at the World Championships in Budapest.
The 28-year-old Jamaican, who ran a world-leading 21.45 to win her first individual World Championship gold medal in July, will take on the USA trio of Jenna Prandini, Gabby Thomas and Tamara Clarke, European champion Mujinga Kambundji as well as Tynia Gaither of the Bahamas with a Diamond League trophy at stake.
Supremely confident, Jackson, sporting new hair while seated next to a braided Shelly-Ann Fraser-Pryce, hinted to members of the media on the eve of the Diamond League finale that the 34-year-old world record of American Florence Griffith-Joyner could be under threat if things go according to plan.
While she didn’t specify what time she was aiming at, Jackson said she set that new goal on returning home to Jamaica after becoming the second-fastest woman all time over the distance following her successful campaign in Eugene, Oregon.
“Before I started the season I wrote that exact time (21.45) on a piece of paper that I left on my trophy stand. I never took a picture with my phone because I wanted that every time I stepped into my house I wanted or go to training, I had that target.
“When I wrote that I went back to training every day and I worked even harder. Some days you might have a bad day but don’t let a bad day get you down.”
The first sign she had that the work she was putting in was paying off was when she ran a then world-leading 21.55 to win at the Jamaica National Championships in June. It was then that she knew that the time she wanted to achieve was within reach.
“Right after the trials, I said ‘okay, it’s coming and I wanted it so bad. Right after trials I went back to training and I achieved that and I am so happy,” she said.
“I went back home though and I wrote a different goal. I wrote another time there because I definitely want to go faster and I think I am capable of doing that. If it’s not done tomorrow then I will come back next season and work even harder.”
Jackson, who also ran a 100m personal best of 10.71 this season, is also on track to win two trophies on Thursday.
She lines up in the 100m finale against friend and compatriot Shelly-Ann Fraser-Pryce and Diamond League points leader Marie Josee Ta Lou of the Ivory Coast, who has run 10.72 this season, a new lifetime best and African record.
Tentoglu entered the sixth and final round of the men’s long jump in third place with a best jump of 8.04m behind the USA’s Jarrion Lawson and Jamaican 2019 World Champion, Tajay Gayle.
The 25-year-old then produced a winning jump of 8.20m in the sixth and final round. Gayle, who took bronze in Budapest, finished second with a best jump of 8.07m done in the fourth round while Lawson’s 8.05m done in round five was good enough for third.
This end of this competition was eerily similar to the competition in Budapest where Tentoglu entered the sixth round trailing another Jamaican, Wayne Pinnock, before coming up big with an 8.52m jump to take gold.
