Sha’Carri Richardson went 2-0 against Shericka Jackson this season after storming to victory in the 100m at the Silesia Diamond League meeting in Poland on Sunday. The American, who remains unbeaten over 100m this season chased down Jackson, nipping the Jamaican at the line to win in a time of 10.76.

Jackson, celebrating her 29^th birthday on Sunday and who ran a world-leading 10.65 to win the Jamaican championships a week ago, clocked in at 10.78. Poland’s Ewa Swoboda ran a personal best of 10.94 for third place.

“It was an amazing race, I am really having fun,” an excited Richardson said afterwards.

“The 10.76 - I love the time. I put a great race together. This was a great competition, it was amazing. I executed correctly. I love the atmosphere here. I wish we could replicate this to the US. All the energy, all the love from the audience. I was satisfied with my race altogether.”

It wasn’t a particularly good day for Caribbean athletes nonetheless the eighth Diamond League meeting of the season delivered plenty of outstanding performances considering that the World Championships are less than five weeks away.

Chief among those performances was the meet record 44.08s South Africa’s Wayde Van Niekerk unleased on a quality field in the 400m. Demonstrating his best form since his return from a career-threatening knee injury in 2017, the South African has Brazil’s Alison dos Santos, himself returning from recent knee surgery, for company up to 300m before the 31-year-old Olympic champion went full throttle down the home stretch putting daylight between himself and the rest of the field.

Bayapo Ndori of Botswana finished strong to slip by the Brazilian and crossed the finish line in a personal best 44.61. Dos Santos, the 2022 World 400m hurdles champion settled for third in a season-best 44.73.

Van Niekerk expressed his satisfaction with the race.

“Things are moving in a positive direction. I have been able to train consistently. It is my fastest run in seven years and 44.0 shows that 43 seconds is possible,” he said.

“The competition in my event is getting stronger, so I need to work to get better as well. I do not feel any special pressure, but it is natural for an athlete to want to reach their best possible level. I will be going on to London now and then want to get some good training sessions before the World Championships.”

Earlier, Poland’s Natalia Kaczmarek delivered a similarly devastating performance in the women’s race that she won in a new lifetime best of 49.48 which was also a new meet record.  Lieke Klaver of the Netherlands also showed she was in good form heading into the world championships clocking in a time of 49.81, which was just shy of Femke Bol’s previous meet record of 49.75.

Marileidy Paulino, the World Championship silver medalist, uncharacteristically outrun over the first 300 metres, stormed through the field late to finish third in 50.00.

Jamaica’s Candice McLeod ran a season’s best 50.19 for fourth just ahead of Barbados’ Commonwealth Games champion, Sada Williams fifth, also in a season’s best 50.34.

 The 100m hurdles was another thrilling affair that saw World Champion Tobi Amusan winning in a season-best and new meet record 12.34 to edge Kendra Harrison, the former world record holder, who finished second in 12.35.

Newly crowned USA champion Nia Ali ran a time of 12.38 for third place.

Breaking down her performance afterwards, Amusan revealed the challenges she has faced while competing this season.

“It was not easy for me with injuries in my hamstring and my knee. But I trusted in my coach and my work,” said the Nigerian who is coached by Jamaican Olympian Lacena Golding-Clarke.

“It is all about the process. I just won this in a smooth style, I was just running. Honestly, I had no idea that I won when I crossed the finish line.”

In reference to the upcoming world championships, Amusan said she was not looking too far ahead.

“I take it one step after the next. I knew it was going to be a battle until the finish line. I am happy to compete against the best. I am just out here doing well. I came out there I was not feeling too good. About my start - I would not say that I executed, but the second part of the race was really good. I am most definitely building up for the World Championships, extremely satisfied with my season-best, one step at a time.

Jamaican champion Megan Tapper was the best placed Caribbean athlete. She finished fourth in 12.49, her second fastest time ever, after the 12.44 she ran at Jamaica’s National Championships a week ago.  Danielle Williams, the 2015 world champion was fifth in a season-best 12.55.

Natoya Goule has been running well all season and she produced another season-best performance to finish third in the 800m. The Jamaican champion ran 1:57.90 but was not fast enough to get by Uganda’s Hallimah Nakaayi who set a new national record of 1:57.78.

However, both women were outrun by Kenya’s Mary Moraa, who sped a new meet record and season-best time of 1:56.85, which sets her up as a legitimate medal contender in the event at Budapest next month.

American Fred Kerley lost his first 100m this season, finishing second to Akani Simbini in a closely contested race in which 0.02 separated the top four finishers. The South African ran 9.97 to Kerley’s 9.98, which was the same time given to Cameroon’s Emmanuel Eseme.

The USA’s 100m champion Cravont Charleston finished fourth in 9.99.

Yohan Blake, the 2017 World Champion, was fourth in 10.01, his best time this season.

Yulimar Rojas was once again dominant the women’s triple setting a world-leading mark of 15.18m, which was also new meet record and season’s best.

Ukraine’s Maryna Bekh-Romanchuk came late to the party with a leap of 14.70m which gave her second place while bumping Cuba’s Leyanis Perez-Hernandez, second for most of the competition, down to third.

Jamaican champion Shanieka Ricketts’ season-best jump of 14.56m saw her finish fifth while Dominica’s Thea LaFond was sixth with 14.43m.

The Tyler Mason renaissance continued in Poland Sunday when he took third-place in a close finish in the 110m hurdles at the Silesia Diamond League meeting.

Mason, who was fourth at the Jamaica national championships last weekend, in 13.22 to just miss out on making Jamaica’s team to the 2023 World Athletic Championships, clocked 13.29, narrowly losing out to Cuba’s Roger Iribarne, who won the event in 13.25 and Frenchman Just Kwaou-Mathey, 13.27.

In finishing third, Mason placed better than former NCAA champion Trey Cunningham and Daniel Roberts, who ran times of 13.36 and 13.90 for fourth and seventh, respectively.
