Thomas and Lyles claim 200m wins in Diamond League opener

American duo Gabby Thomas and Noah Lyles took impressive 200 metres victories and two men posted monster, wind-assisted 90 metre javelin throws as the Diamond League season got underway on a lively night in front of a noisy crowd in Doha on Friday.

In the women's event Jamaica's Shericka Jackson looked set to open with victory only for Thomas to surge past in the last 20 metres to match the meeting record with an impressive early season 21.98 seconds.

Jackson posted 22.07 with Britain's world champion Dina Asher-Smith fading to 22.37 in third.

They also switched ends for the javelin throwers and Tokyo silver medallist Jakub Vadlejch quickly took advantage of the wind with a throw of 89.87 metres, beating his five-year old
