In the 1500m, Scotland’s Jemma Reekie finished a credible third with a time of four minutes 7.33 seconds as Nelly Chepchirchir strode clear in 4:05.00, ahead of Kenyan team-mate Susan Ejore.
Elsewhere, Amy Hunt finished third in the 100m in a time of 11.03 as she took .09 seconds off her personal best.
The race was won by Tia Clayton, who outshone two-time Olympic 100m champion and Jamaican compatriot Shelly-Ann Fraser-Pryce.
The 38-year-old Fraser-Pryce was competing on the Diamond League circuit for the first time in three years, but could only finish fourth as Clayton, 20, won easily in a world-leading time of 10.92.
Clayton’s twin sister Tina was second in 11.02, while Fraser-Pryce, competing in possibly her final season, clocked a season’s best 11.05 for fourth.
Reigning men’s Olympic 200m champion Letsile Tebogo produced a lacklustre performance for success in his signature event as he was almost caught on the line by Courtney Lindsey.
Botswana’s Tebogo ran a smooth bend but seemed to lack fluency in the home straight and glanced to his right at Lindsey as he crossed the line in a modest 20.10, one hundredth of a second ahead of the American.
In the men’s 800m, Tshepiso Masalela chased down Wycliffe Kinyamal to clock 1:43.11, the fastest time in the world this year.
Meanwhile, Lawrence Okoye finished sixth in the discus with a throw of 65.01m, while fellow Briton Laviai Nielsen finished seventh in the 400m with a time of 52.02.
