After the 20-year-old Swede cleared the 60m mark for the fifth time in his career, he raised the bar to 6.17m - just above Renaud Lavillenie's world record.

And he came painfully close to breaking it too, brushing the bar with his arm on his way down on his second attempt when it looked like he might be over.

"That second attempt at 6.17 was as good as I could have expected," he said after. 

Duplantis added that he feels "very fit" and is "excited about the rest of the season."

There were six world-leading performances on the night and Beatrice Chepkoech produced another of them, breaking the Kenyan women's 1,500m record in a time of 4min 2.09sec.

Adam Kszczot's run of seven consecutive Düsseldorf victories came to an end in the men's 800m and in fitting fashion too, with Düsseldorf's own Marc Reuther the man to beat the Pole.

"Having the crowd behind me really helped push me past Kszczot," Reuther said after winning in a time of 1:46.13.

Other notable results included Ethiopia's Selemon Barega winning the men's 3,000m in a world-leading 7:35.71 and Croatia's Filip Mihaljević throwing the shot put 21.52m.

American Christina Clemons defended her 60m hurdles title and Dutch sprinter Lisanne de Witte ran a personal best of 52.30 to win the women's 400m - her first World Athletics Indoor Tour victory.

The Gambia's Gina Bass and Britain's CJ Ujah won the 60m sprints in times of  7.61 and 6.54 respectively.
