In Engadin, Sweden's first team finished fifth after Jens Burman skied the first leg of the mixed relay, 4x5 kilometers.
Then Emma Ribom took over, in her first mixed relay ever, and was able to catch up and create a distance to the rest of the field together with Finland.
At the third exchange, Sweden was in second place. But then Edvin Anger stepped into action.
The 22-year-old was able to easily catch up and then pull away, where the good form after the sprint victory last in Les Rousses holds up.
I was eager to go out and ski. I got a good starting position where I talked to Remi (Lindholm, Finland's skier) where he said he was too tired, so I got to ski. Which I did and managed to give Moa an even better starting position, says Anger.
"The form is on the way"
The positive starting position could Moa Ilar capitalize on in a fine way when she finally crossed the finish line 19.5 seconds ahead of Norway's first team, which finished second.
Super cool. I had a very good lead that the team before me had created. So very cool to ski today, says Ilar and continues:
We're showing that the form is on the way for many of the skiers, so I think it's going to be very exciting in the World Championship in Norway soon.
"Strong team effort"
Sweden lacked several of the big stars, but still managed to put together two notable teams.
A strong team effort from start to finish, so sick cool, says Emma Ribom.
It was Sweden's third consecutive victory in the mixed relay in the World Cup.
Sweden's second team had it tougher. After Calle Halfvardsson changed as sixth after the first leg, they fell back in the field and finished tenth.
The competitions in Engadin continue on Saturday with a sprint in freestyle.
