A narrow victory over Bradworthy sent Torridgeside back to the top of the North Devon League premier division this afternoon.
First-half strikes from Marc Bettiss and Rob Holland were enough for a 2-1 win at Donnacroft, moving Torridgeside above Bideford reserves on goal difference.
The result means the title race will go down to the final day with the top two teams level on points.
Torridgeside's goal difference is just one better than Bideford's and the championship could be decided on who can win by the biggest margin on Wednesday evening.

"It was a very stubborn defence and we just couldn't break them down," he said.
"We worked hard but it wasn't a day when we were going to score a lot of goals."
