It is the third time veteran Fredricson wins the largest class in Sweden International Horse Show.
On Vroom de La Pomme Z, Fredricson was the fastest, just over seven tenths ahead of Amanda Landeblad on For Killy.
It's nice to feel that you have a horse that is developing and that is stepping up and going in and winning, says Fredricson in the victory interview in the arena.
Rolf-Göran Bengtsson on Zuccero finished third.
Historic triple
It is the first time in the competition's history that it is all-Swedish on the podium.
The victory gave Peder Fredricson just over 400,000 kronor in first prize.
It has been a long weekend and we have fought for hundredths, nice to get it, says he.
Nine teams made it to the jump-off, but Henrik von Eckermann did not get that far.
A mistake in the basic round meant that the world number one did not get to be part of the final battle.
Henrik von Eckermann won the international show jumping on Saturday evening and then took revenge on Peder Fredricson, who won the 1.45-meter jumping on Friday. Then on Hansson.
"Superb audience"
Fredricson enjoyed standing highest on the podium in the most prestigious class.
Moreover, on home ground in front of an enthusiastic audience.
It's a wonderful feeling to ride here, it's a superb audience and great atmosphere.
