Ivybridge booked their place in the county under-14 cup last eight by beating Cullompton 33-21 away on Sunday.
That followed on from a win over Torquay Athletic in the preliminary round.
George Partridge gave Ivybridge the lead with a try, which Ben Lavers converted, before Cullompton pulled level.
The Bridgers, though, went 19-7 ahead with James Pullen creating a try for Ben Lavers before he got his own touch-down. Nick Lilley converted Lavers’ score.
The hosts closed the gap to just seven points and Ivybridge had to defend hard to keep them out again before half-time.
After the interval, Paul Mears-Baldwin made his speed and power tell to score a try, which Ben Lavers converted to make it 26-14.
Ivybridge prop Elliott Harwood made a storming run but was just thwarted before he reached the whitewash.
With ten minutes to go, a third converted try brought Cullompton to within five points of the Bridgers and set up a tense ending.
But Ivybridge controlled the closing stages well and Mears-Baldwin sealed the match with his second try of the day.
They will now play Tiverton away in the last eight in January.
In the same competition, Tamar Saracens narrowly lost 24-20 away at Withycombe, while Plymstock Albion Oaks were beaten 50-7 by a strong Kingsbridge side.
