Perranporth 2, Sticker 3
Sticker fought back from two goals down to beat Perranporth and extend their unbeaten run to nine game, writes Lee Hall.
Andy Avery's men trailed 2-0 inside the opening 26 minutes but goals from Chris Kitson (39), Lewis Prince (45) and Liam Dingle (51) clinched an impressive win.
Perranporth led after 16 minutes when Ed Wilton produced a superb finish into the top corner.
Sticker had a chance to level in the 22nd minute but John Preece saved Dingle's penalty.
The impressive Wilton then added a second goal for Perranporth in the 26th minute after good work down the left by Bryan Hawke.
Sticker pulled a goal back in the 39th minute when Kitson pulled a goal back from close range.
And they were level just before the break when Prince volleyed home from the edge of the area.
Dingle then made amends for his half penalty miss when he grabbed what turned out to be the winner in the 51st minute, lobbing the ball over Preece.
