World 200 metre champion Shericka Jackson gave the clearest indicator yet that she will be the one to beat in that event at the upcoming World Championships with a convincing victory at the Monaco Diamond League meet on Friday.
Meanwhile, it was a dramatic maiden Diamond League appearance for teenage sensation Jaydon Hibbert.
Jackson clocked 21.86 seconds to win the event ahead of St Lucia's Julien Alfred 22.08 and Great Britain's Diner Asher-Smith who posted a season's best 22.23.
There was drama in the men's triple jump where teenage sensation Jaydon Hibbert just missed on winning the event in his maiden Diamond League appearance.
Hibbert led with 17.66 meters going into the final round "jump off" among the top 3 where Burkino Faso's Fabrice Zango came up with a massive 17.70 metres to win the event.
Ackeem Blake was the next best placed Jamaican with a third place finish in the men's 100 metres clocking 10 seconds flat.
Kenya's Ferdinand Omnayala sped to 9.92 to win the event. Yohan Blake was 4th in a season's best 10.01, while Kishane Thompson ended 5th in 10.04.
World leader Ackelia Smith ended a disappointing 7th in the women's long jump with a best effort of 6.67 metres.
The event was won by Larissa Iapichino with 6.95 metres.
Meanwhile, the meet was also highlighted by Kenya's Faith Kipyegon who clocked a world record 4 minutes, 07.64 seconds to win the women's mile. The next Diamond League meet is on Sunday in London.
