The Cornish Pirates sealed a bonus-point victory over local rivals Plymouth Albion in the Championship.
Joe Atkinson's score put Pirates ahead, but four Declan Cusack penalties helped Albion to a 12-8 half-time advantage.
Joe Atkinson scored his second try after the break to give the Pirates a 15-12 lead.
Alex Dancer and Tom Harrison then exchanged tries, and an unconverted Max Bodilly score was enough for the Pirates to seal the win.
Albion remain rooted to the foot of the Championship table, without a league win this season.
