It was an increase of her personal record by 13 centimeters.
Duplantis is the new Swedish champion this year and the eighth best pole vaulter in the country in history, Expressen and Aftonbladet write.
The 22-year-old cleared the first two attempts at 4.39 meters before she cleared the bar in the third. She finished eleventh in the competition.
She wants to compete in Finnkampen in the summer, says father Greg Duplantis to Aftonbladet and confirms that they have been in contact with national team coach Kajsa Bergqvist.
It was a good Thursday for the Duplantis family. A few hours earlier, older brother Armand had won the Diamond League competition in Oslo with 6.15 meters.
It's hard to explain what crazy development she has had this season. I'm so happy for her, he said about Johanna Duplantis according to Aftonbladet.
