He held the final in an iron grip and was high all the way to the victory height of 2.37.
He then stood above 2.39 and tried at the championship record height of 2.42 without success.
Barshim is the first high jumper to win three World Cup titles, also in a row.
- I'm so happy and that was my goal.
It was difficult to find the motivation and I had to find something that stimulated the hunger in me.
It's not the same after Tokyo.
I feel empty and when I competed in the Diamond League I had barely trained at all and I do not want that, says Barshim about the problems he faced until the World Cup in Oregon.
- For the World Cup, I had to try to find something and I wanted to win three times in a row and do something for the history books.
That was what motivated me and I am so happy that it turned out that way, he says.
Bronze with a suitcase
You really jumped great tonight?
- It's about analyzing the jumps.
I look at them a thousand times.
When I do high jump, I really do.
When I'm not jumping high, I're always thinking about how to get better.
That's how I create quality, says Barshim.
Second was South Korean Sanghyeok Woo at 2.35.
He then tore once at 2.37 and saved two jumps to 2.39 and tore there as well.
Third Andriy Protsenko comes from war-torn Ukraine.
He managed 2.33 and is trying to make everyday life go together.
- My main goal is to find somewhere to live with my family in Europe to prepare for the European Championships and the Diamond League.
It is a difficult situation and I had to leave everything in Ukraine and have only traveled with a suitcase, says Protsenko.
