American dream: Victorious Christian Coleman and Sydney McLaughlin lead United States' celebrations in Norway
Christian Coleman clocked a blistering 9.85 seconds to win the Oslo Diamond League 100m.
The 2018 Diamond League champion was searching for his first win this term, having been pipped by fellow American Noah Lyles in Shanghai's thrilling season opener.
But the absence of Lyles and his other main sprint rivals in Oslo meant Coleman was the clear favourite heading into this race.
And the explosive sprinter didn't disappoint.
Just as the sun replaced the day's earlier rainy conditions, Coleman outshone his competition to secure the title and bragging rights as the world's fastest man this year.
Starting the season with two sub-9.9 second times will be a welcome return to consistency for Coleman.
Last year, the 2017 100m world silver medallist was hampered by an early season hamstring injury.
He was firing again by the end of 2018, running 9.79 seconds to secure the Diamond Trophy and resume his place atop the world of sprinting.
Sydney McLaughlin scored her first Diamond League victory in style, coming from behind in the 400m hurdles.
After clattering the first obstacle, the junior world record holder was left with plenty of work to do.
The 19-year-old was still trailing Olympic champion Dalilah Muhammad coming into the final straight, but finished strongly to beat her compatriot on the line in 54.16 seconds.
It was McLaughlin's first win over Diamond Trophy holder Muhammad with fellow Americans Shamier Little and Kori Carter in third and fourth respectively.
