L'indépendance Luxembourgeoise - McLaughlin sets worlds alight as Miller-Uibo, Norman claim 400m crowns

In a consummate display of front-foot running, McLaughlin left a loaded field for dead from the gun, haring through the tape in an astonishing 50.68 seconds. It sliced more than half a second of her previous world mark of 51.41sec set last month.

Femke Bol of the Netherlands took silver in 52.27sec while defending champion Dalilah Muhammad of the United States took bronze in 53.13.

To put McLaughlin's staggering performance in perspective, her time after negotiating 10 hurdles over 400m would have seen her beat two runners in the women's flat 400m final, raced just minutes beforehand.

That race was won by two-time Olympic champion Shaunae Miller-Uibo of the Bahamas.

Miller-Uibo, who was deprived of gold in Doha in 2019 by Salwa Eid Nasr of Bahrain -- since banned from the Tokyo Games and these championships after three missed doping tests -- timed a world lead of 49.11sec at Hayward Field.

Marileidy Paulino of the Dominican Republic claimed silver in 49.60sec, with Sada Williams of Barbados taking bronze in a national record of 48.75.

The men's one-lap final was claimed by American Michael Norman, whose victory made up for a disappointing fifth-placed finish at the Tokyo Olympics.

Norman, who failed to advance from semi-finals in the Doha worlds in 2019 with a thigh injury, clocked a winning time of 44.29sec.

Three-time Olympic medallist and 2011 world champion Kirani James of Grenada claimed silver with 44.68sec, while Briton Matthew Hudson-Smith took bronze (44.66).

World record holder Wayde van Niekerk of South Africa, who set the record of 43.04sec when winning gold at the Rio Olympics, finished fifth in 44.97sec.

Australian Kelsey-Lee Barber retained her javelin title, the current Olympic bronze medallist throwing a best of 66.91 metres.

There was drama in the battle for silver and bronze, however, as American Kara Winger (64.05m) and Japan's Haruka Kitaguchi (63.27) snatched the resepective medals with their sixth and final throws.

- Easy does it for Duplantis -

Sweden's Mondo Duplantis made first appearance at Hayward Field, easily qualifying for Sunday's pole vault final.

The US-born world record holder and Olympic champion, seeking to improve on his world silver from Doha, was faultless up to his 5.75m qualifying mark.

Olympic champion and home favourite Athing Mu led US teammates Ajee Wilson and Raevyn Rogers into the final of the women's 800m.

Also making the final are Kenya's Mary Moraa, Briton Keely Hodgkinson, Jamaica's Natoya Goule, Ethiopian Diribe Welteji and Slovenia's Anita Horvat.

The United States safely negotiated the heats of the 4x100m relays.

Christian Coleman, newly-crowned 200m champion Noah Lyles, Elijah Hall and Marvin Bracy breezed around in a world leading 37.87sec.

The world champions in Doha, featuring Coleman and Lyles in that line-up, could only finish sixth in last year's Tokyo Olympics.

But the US team held a pre-worlds relay camp for the athletes to better hone their baton-exchanging skills.

The final will also comprise France, Canada, South Africa, Jamaica, Brazil, Britain and Ghana.

There was no place for Olympic champions Italy, missing Tokyo's individual 100m champion Marcell Jacobs through injury.

Melissa Jefferson, Aleia Hobbs, Jenna Prandini and Twanisha Terry got the baton around in 41.56sec for the US women.

Also qualifying for Saturday's final are Britain, reigning world champions Jamaica, Germany, Spain, Nigeria, Italy and Switzerland.

Jamaica did not call on five-time world 100m champion Shelly-Ann Fraser-Pryce, 200m champion Shericka Jackson and four-time Olympic individual medallist Elaine Thompson-Herah.
