Jamaica’s Olympic champion Elaine Thompson-Herah signalled some semblance of improvement, as she clocked a season’s best 11.00 seconds for third behind newly minted World Champion Sha’Carri Richardson in the women’s 100m at the Wanda Diamond League in Zurich, Switzerland on Thursday.

Thompson-Herah, who has been struggling to get back to her best after battling injury, ran a well-paced raced from a tidy break, but couldn’t get back to Richardson, who continues to display her superb form this season.

The American won in 10.88s, with another Jamaican Natasha Morrison (11.00s), running her heart out from lane one, to edge Thompson-Herah for second.

Thompson-Herah’s time bettered her previous season’s best of 11.06s, and though it is well off her personal best of 10.54s, it signals a step in the right direction since she started working with Shanikie Osbourne on a provisional basis.

Meanwhile, Shashalee Forbes (11.2s), the other Jamaican in the event, placed fifth, while Anthonique Strachan (11.39s) of the Bahamas failed to figure on this occasion, placing ninth.
