Thompson, Jackson set the 100m pace at Jamaican trials
Kishane Thompson has registered a sizzling world-leading mark of 9.77 seconds to win the men's 100 metres at the Jamaican Olympic trials.
Two-time world championships finalist Oblique Seville was second in 9.82, while world indoor 60m bronze medallist Ackeem Blake finished third in 9.92.
Thompson, in only his second season as a professional, had not raced at all this year before the Jamaican championship.
"My coach instructed me just to run the first 60 metres, nothing more, and after that shut it down," he said.
"If I came second or third, I would've made the (Olympic) team. The goal wasn't to prove anything tonight, just run the 70 or 60 metres and see where I was."
Thompson - now the fourth-fastest Jamaican behind Usain Bolt, Yohan Blake and Asafa Powell - said he has much to improve on when he makes his Olympic debut in Paris.
"It's kind of new to me, but I'm getting it slowly," he said.
Shericka Jackson recovered from a poor start to win the women's 100m in 10.84, clawing her way from the back of the field after 30 metres to power past Tia Clayton (10.90) and twice Olympic champion Shelly-Ann Fraser-Pryce (10.94).
Jackson, back-to-back world champion in the 200m, said winning was more important than running a faster time.
"It's a work in progress and I will now turn my attention to retaining my 200m title over the next two days," she said.
Malik James-King won the 400m hurdles in 47.42, moving up to No.5 in the world this season as he crossed the finish 0.62 seconds ahead of national-record holder Roshawn Clarke. Jaheel Hyde was third in 48.35.
In the women's event, twice world championship bronze medallist Rushell Clayton sped to a lifetime best 52.51, the second-fastest time this season, to secure her first Olympic berth.
"My aim was to execute an awesome race ... I got my stride 99 per cent close to perfect tonight to move up to 52.51," she said.
Janieve Russell (53.33) and Shiann Salmon (53.71) completed the podium spots.
Deandre Watkin ran a massive personal best of 44.48 to win the men's 400m.
