The Robins number one scored 12 points as the Danes won Event Two in Vastervik, but Nicki Pedersen and Niels-Kristian Iversen will come into the team for the final with Hans Andersen and Bjarne Pedersen making way.
Kildemand has kept his place along with Mads Korneliussen, with Secher admitting his decision was a tough one.
He told www.monsterenergyswc.com: “I picked Mads because he was absolutely the best gater for the Danish team tonight. I didn’t have any doubt about him after the meeting.
“I had doubts whether I should go for Peter or Hans because they were almost even in my opinion. They both scored 12 points and they both made good starts. They also gave it a go on the track.
“It went to Peter because I thought he was more of a fighter than Hans tonight – that’s what made the difference. But it was a very tough call for me. Hans was gating so well.
“The meeting I had with the riders after the event was a tough one. Hans will still be involved in Bydgoszcz. It’s his home track in Poland and I’m sure he can provide important information about it if we need it. He’ll be there and he is a team player.
“He told me ‘I’m up for that. No problem.’ That tells you something about the rider. Of course he is disappointed and so was Bjarne Pedersen, who also gave it a good go. But they’re there for the team, they’re there for Denmark and I am proud of them.”
