Duplantis stood above the entry height of 5.30 and went straight into 5.50 in the pole vault qualifier at the Tokyo Olympics.
He started by tearing, but then easily slipped over 5.50 in the second attempt.
Then Duplantis flew high above 5.65.
"I can jump really high here"
Duplantis looked focused as he raised the pole to sprint towards his first jump of 5.75, which did not cause any problems for the 21-year-old.
5.75 turned out to be the height that took Duplantis to the first Olympic final of his life.
- It was really fun.
In the first attempt at 5.50 I was a little too tagged.
I was a little too fast, so I tore.
I switched to a stronger rod, Duplantis said in Discovery + broadcast.
- There was not much sleep before the qualifiers, but the final is in the evening so then I can sleep a little more.
It feels great.
I can jump very high here, Duplantis continued in sounding Swedish.
The Frenchman Renaud Lavillenie, former world record holder, had a tougher road through the qualifiers, but managed to take 5.75 in the last attempt, which also took him to the final on Tuesday.
