Olympic Games gold, three world records and victory in every competition.
Duplantis could summarize an incredible season after the victory in Brussels.
It's an entirely incredible season for me and I wanted to finish with a victory and the title, he says.
When the victory was secured, he raised the bar to 6.11, which is the stadium record in Brussels, and easily cleared it.
Duplantis only made three attempts in the competition. He started at 5.62, then cleared 5.92 – where he secured the victory – and finally the stadium record.
"Glad the season is over"
There was no world record attempt this evening, however.
Three world records this year will have to suffice. The latest came on August 25 in Katowice at 6.26 – the most impressive in the Olympic Games final in Paris on August 5 at 6.25.
My body feels like crap, it's been a pretty tough week. I'm glad the season is over, says Duplantis.
Last week, Duplantis won the highly publicized sprint duel on 100 meters against Karsten Warholm in Zurich.
My body is not used to sprinting, and I haven't trained much after the Olympic Games, says Duplantis, who looks forward to taking it easy and also celebrating his incredible season.
The pole vault star could collect around 300,000 kronor for the victory in the final competition.
Emmanouil Karalis, Greece, finished second at 5.82 and the home favorite Ben Broeders, Belgium, third at the same height.
Ståhl fourth
Daniel Ståhl was the second Swede in the Diamond League final and his evening was a bit like the discus star's season has been overall.
Ståhl finished fourth at 66.26, barely three meters from his season's best and over five meters from his Swedish record.
Matthew Denny won the competition after setting an Australian record at 69.96 already in the first round.
The runner-up Mykolas Alekna was just over a meter behind at 68.86.
