Jamaica’s Shericka Jackson produced her usual strong finish to be crowned Diamond League champion in the women’s 100m, while compatriot Elaine Thompson-Herah continues to upgrade with a season’s best time for third at the Prefontaine Classic in Eugene on Saturday.

Like the men’s event, the women’s dash was just as explosive, with Jackson, the World Championships silver medallists, registering her first 100m victory over American World Champion Sha’Carri Richardson to end that chapter of her season on a high.

Jackson, who is also favoured for the 200m crown, clocked 10.70s with a storming finish from lane six, as she swept by the fast-starting Marie-Josee Ta Lou, who clocked a season’s best equaling 10.75s.

Double Olympic champion Thompson-Herah once again demonstrated that she is gradually overcoming her struggles with injuries with a season’s best 10,79s.

Richardson was fifth in 10.80s, while another Jamaican Natasha Morrison clocked a big personal best 10.85s in sixth.
