China hijacked the final of the women’s 4x100m relay event on Sunday at the world championships with one of the ugliest runs ever seen on the track.

The Chinese team was eventually disqualified and now has its Olympics qualification up in the air following a horrific baton handover that went as bad as it possibly could.

Extraordinary video of the blunder from the final shows two runners over-stepping the allowed area during a baton handover, before jogging back into the handover area.

In between the desperate dash back to the handover, two runners appeared to disagree over which of them should be carrying the baton. Even when they’d returned to the allowed zone, the runner didn’t even take off until after she’d been pushed in the right direction.

It was a perfect trainwreck that left commentators in Doha unable to keep a straight face.

The official records showed the Chinese team of Liang Xiaojing, Wei Yongli, Kong Lingwei and Ge Manqi finished more than 23 seconds behind the seventh-placed Italian team in a race won by Jamaica in a time of just 41.44 seconds.

The top eight teams secured direct qualification for next year’s Olympics in Tokyo, but China’s qualification is yet to be confirmed following its disqualification.

Jamaican sprint legend Shelly-Ann Fraser-Pryce secured her ninth world title with the win.

The 32-year-old, who won her fourth world 100m title last Sunday, ran a storming second leg to put Jamaica firmly in the driving seat.

Shericka Jackson had a big enough lead to breach the line in 41.44 seconds with Britain’s 200m world champion Dina Asher-Smith anchoring her team to the silver (41.85sec).

For Asher-Smith, it completed a superb championships as she also took silver in the 100m.

Defending champions the United States rounded off an underwhelming championships for its 100m and 200m women sprinters, taking bronze in 42.10.
