Jamaica’s Stacey-Ann Williams and Trinidad & Tobago’s Jereem Richards were the only Caribbean winners at Tuesday’s Spitzen Leichtathletik Meet in Luzern, Switzerland.

Williams turned back the challenge of Dutchwoman Lisanne de Witte and Switzerland’s Annina Fahr to win in 50.58, her second fastest time this season, trailing behind her 50.56 to finish second at Jamaica’s National Championships in June.

De Witte and Fahr’s times in second and third were 51.99 and 52.08, respectively.

Richards, the 2017 World Championship bronze medallist and two-time Commonwealth Champion, all in the 200m, won the half-lap event on Tuesday in 20.19 ahead of the Zimbabwean pair Makanakaishe Charamba (20.42) and Tapiwanashe Makarawu (20.48).

The 30-year-old Trinidadian will also compete in the 400m in Paris. He won gold in the distance at the World Indoor Championships in 2022.

Another Jamaican Olympian, Lanae-Tava Thomas, was narrowly beaten by the Ivory Coast’s Jessika Gbai in the 200m.

Gbai’s winning time of 22.57 just beat out Thomas’s 22.60 while Switzerland’s Mujinga Kambundji was just behind in third in 22.61.

Kemba Nelson ran 11.21 to finish third overall in the women’s 100m behind New Zealand’s Zoe Hobbs (11.17) and Kambundji (11.20).
