Table runner-up Västervik received the third, revenge-hungry Lejonen who came to the match with two straight losses behind them.
Dark clouds hung over Hejla Arena before the meeting, but luckily the rain did not come.
It was a smooth start to the summit.
But after heat seven, Västervik started to pull away when Vadim Tarasenko won and 17-year-old Noel Wahlqvist took second place after a very good run.
Which gave Västervik the lead with 26-16.
In the heat after, Västervik took his fourth fifth, the third straight, through victory for Viktor Kulakov and a second place for Bartosz Smektala.
The Lions thus had a proper uphill in front of them at a disadvantage with 31-17.
"More than happy"
In heat nine, the pot was split and the Lions got a small chance to catch up, but this evening Västervik was too difficult to handle.
Before the nomination heat, the home team led 45-27.
The Lions won the fourteenth heat but it did not help much and Västervik won in the end with 54-36.
The best scorer was Viktor Kulakov who took 13 points tonight.
- We meet a really good team but after the first three heats we dominate.
I am more than satisfied, says Morgan Andersson.
A heavy third straight loss for the Lions chasing a secured playoff spot.
The blacksmiths took great victories
In Eskilstuna, Smederna took a superior victory against visiting jumbo Piraterna.
Series-leading Smederna thus bounced back immediately after the loss against Rospiggarna on Thursday.
After nine heats, Smederna was in a 14-point lead, 34-20, and the Pirates could never challenge properly.
Before the nomination heat, the home team led 47-25.
In heat 15, Smederna took the seventh fifth.
In the end, it was a real crush by Smederna who won by a full 60-30 and pulls away even more at the top.
A lead-heavy seventh straight loss for the Pirates who are last with just one run-in point.
In Kumla, the rain stopped it and the match between the Indians and Vetlanda had to be postponed.
