Newton Abbot are up to third in National Three South West after a 28-22 win over previously unbeaten Weston.
It is all change at the top with London Irish Wild Geese installed as the new leaders following their 22-17 win over Redingensians and Weston down to second, a point up on Newton and Chippenham in joint third place.
Newton were always ahead in the match – 10-0, 18-15 and 28-15 – but never far enough to sit back and feel comfortable.
A two-try burst made the game just about safe, although director of rugby Roy Henderson was honest in his post-match assessment.
"It as a bit dodgy at 18-15, then Matt Newman and Brett Stroud scored tries three or four minutes apart and it felt a bit more comfortable," said Henderson.
"Beating the leaders inevitably means one or two people around the club wondering how far we can go this season? It is a bit early for that sort of talk after six games – I told them to ask me at the end of March if we are still third then."
Josh Smith and Ben Cole were Newton's other try scorers, with Rob Avery-Wright adding a conversion and two penalties.
Brixham coach Dan Parkes was cooing with delight after his side's 28-3 win over Barnstaple in the Devon derby hoisted them into fifth place.
"Defensively, it was our best performance in the three and a half years I have been at the club," said Parkes.
"Our line speed was good – we flew up at them – and looked very safe.
"Sometimes when we score an early try, as Harry Davis did, it is easy to go off the boil. This was one game where we put in a performance for the full 80 minutes."
Kevin Squire, director of rugby at Barnstaple, had no complaints, other than that his side didn't make the best of their chances in an improved second half.
He said: "Brixham were fit, aggressive in the right way and bang up for it – the hallmarks of a good side. Over the past couple of years they have become a force in Devon rugby and can go on to better things."
Kyle Browne and Matt Clarke (two) were the other Brixham try scorers, Ben Lovell landed three kicks.
Exmouth are right behind Brixham in sixth courtesy of a hefty 58-10 win over visiting Amersham.
"We were too good for them in lots of areas, especially the backs where or phusicality surprised them," said Exmouth's director of rugby Chris Wright. Andrew Powell had a try hat-trick in his personal haul of 28 points.
Taunton ended a three-match losing run in National Two South by winning 33-33 at Southend.
The Titans were ahead after No.8 Dean Taylor-Menzies put them there with a try converted by player-coach Tony Yapp.
Mike Pope, Jemba Bull and Will Carrrick-Smith all contributed tries with Yapp converting one of them and Brett Turner slotting three penalties.
