Four years ago, Duplantis won his first senior international championship (EC) when he jumped 6.05 on a magical night of athletics at the Olympiastadion Berlin.
After Saturday's competition, he is now a two-time European champion, both times on German soil and again at an Olympic stadium.
The rain poured down all afternoon in Munich and had some impact when it was time for the pole final to get underway, the tracks were still wet.
The big favorite Duplantis chose to enter the competition at 5.65 and managed as if he had never done anything else.
When the others were then going to jump at 5.75, the two most successful jumpers, Duplantis and Renaud Lavillenie, decided to stand over.
Seven jumpers went further to 5.85.
There, Duplantis was the only one who passed in the first attempt.
- A nicely balanced jump by Armand.
He pushes very powerfully in the insertion and gets a response from the staff, says SVT's expert Alhaji Jeng.
Two jumpers left at 5.90
At 5.90, only two jumpers remained, Duplantis and home jumper Bo Kanda Lita Baehre who chose to stand above 5.85.
Duplantis made it right away - while the German tore his way to the top.
- He is completely superior, says SVT's Jacob Hård.
- What makes it so impressive is that he is like a clock at the approach.
That is ridiculous, says Jeng after "Mondo's" jump over 5.90.
