Birmingham Brummies missed the chance to claim victory at local rivals Wolverhampton on Monday.
The Brummies looked good to take something from Monmore Green for much of the evening and were two-points up with five races remaining.
But Wolves finished with consecutive 5-1s to seal an unlikely 49-41 victory.
The highlight of the evening for Wolves was Great Britain star Tai Woffinden who returned from injury to score an excellent 13 and lead them home.
However, it was Birmingham who could not hide their disappointment.
Brummies boss Phil Morris said: "It's very disappointing to see an outcome like this because we had fought back and got ourselves into a good position.
"Conditions were tough but it was the same for both teams and I told my riders at the interval all we needed to do was avoid last place and we weren't capable of doing it. I'm bitterly disappointed and we need to put it right at home to Coventry on Thursday."
Wolves boss Peter Adams was delighted to have taken the win.
"We are delighted to come away with a win. The Brummies are a hard team to beat because they are very compact and they have got a very good reserve in Auty obviously, so they are always going to be problem wherever they go," said Adams.
"Tai Woffinden came back with a back injury but still top scored in very difficult conditions, so we were delighted with him, and now he has a few days rest before he heads off to Sheffield for the British Championship Semi-Finals.
"I'm sure our fortunes will change in the second half of the season. We have been struggling with serious injuries for nine week now, which is a very long time, and no team would have coped with that.
"But the team is back together now, and it is in much better shape."
