Werrington took the Cornwall Twenty20 title after beating Falmouth by 47 runs to win the WT Edwards Cup final at Truro on Wednesday.
After being put in Werrington made 163-6, with Alex Smeeth hitting 49 and Adam Hodgson anchoring the innings with 51.
Opener Richard Kellow top scored with 22 for Falmouth but after reaching a promising 37-0 the innings subsided to 116 all out.
Werrington will now play in the National T20 Area Finals on 11 August.
"We're really pleased - we were excellent from start to finish," Werrington captain Ben Smeeth told BBC Radio Cornwall.
"We wanted to bat first anyway and we got a good start and just carried that right through. It was always going to be a tough target for Falmouth to chase down.
"We're really looking forward to the national competition - we'll take a big bus up as a club so it will be a good day out, and hopefully we can represent Cornwall well."
