Launceston coach Simon Owens says he is "over the moon" to beat Cornish rivals Redruth 20-10 in National Two South.
James Salter's try just before the break saw Launceston lead 7-3 after Aaron Penberthy had opened the scoring with an early Redruth penalty.
Kieron Lewitt kicked a penalty just after the break before Paul Andrew scored a try after 54 minutes.
Lewitt kicked another penalty with eight minutes left before a late Paul Thirlby try for Redruth.
"We're over the moon with the performance and it's great to see the scoreboard show 20-10," Owens told BBC Radio Cornwall.
"It was a very good day, we came off second best down at Redruth in the early part of the season and the boys had a point to prove.
"It was a typical Cornish derby, two big packs of forwards going hammer and tongs at each other," he added.
And Owens levelled special praise for Paul Andrew.
The prop came in as an emergency loan from the Cornish Pirates after Launceston suffered a number of injuries in the front row.
"He really helped us today, and for me he was man of the match. He carried well and scrummaged outstandingly well," he said.
