Elsewhere in the top half of the division, Redingensians returned to winning ways as they beat Bury St Edmunds, Canterbury held their nerve to claim victory over London Irish Wild Geese and Henley Hawks came from behind to triumph over Clifton.

Chinnor 13-7 Taunton Titans
Chinnor maintained their unbeaten record in National Two South as an excellent defensive display earned them victory over Taunton Titans at Kingsey Park.
Matt Williams’ side have not lost this term, but this was a vital victory against one of their possible promotion rivals.
A try from Phil Chesters followed by a Jonny Bentley penalty gave Chinnor an 8-0 lead at the break.
Jamel Hamilton added to Chinnor’s total at the beginning of the second-half, but Taunton set-up a tense finale when Kenny James crossed.
However, Chinnor were able to stay strong and clinch the win which now leaves them nine points clear of third place Taunton.
Cinderford 49-19 Redruth
Cinderford are now just a point behind league leaders Chinnor as they ran in seven tries to thrash Redruth at Dockham Road.
Jack O’Connell scored tries in both halves and Reuben Norville grabbed a brace as Cinderford recorded their sixth consecutive victory.
Lewis Beer, Roger Birkin and Ed Bouge also touched down for the bonus point, while Kyle Marriott, Shaun Buzza and Sam Matavesi scored for Redruth.
Redingensians 29-17 Bury St Edmunds
Redingensians beat Bury St Edmunds for their seventh win in eight National Two South matches to tighten their grip on fourth place in the table.
The Rams broke the deadlock through a Connor Corrigan try before a Greg Illingworh score gave them a 12-5 lead at the break, with Will Affleck replying for the visitors.
Tries from Andy Amor and Illingworth extended Redingensians’ lead with still over 30 minutes to play and despite Dwayne Corcoran and Will Scholes going over for Bury, the Rams saw out the game.
London Irish Wild Geese 22-26 Canterbury
Canterbury battled to their ninth win of the campaign as they narrowly beat London Irish Wild Geese in Sunbury-On-Thames.
Canterbury led at half-time thanks to Dan Smart and Jim Green scores while Archie Mackay and Tom Barker went over for Wild Geese.
Brad Clements’ converted try and an Alex Seers penalty put Wild Geese ahead before a penalty try and a score from Seb Clark clinched victory for the visitors.
Henley Hawks 30-20 Clifton
Henley Hawks came from behind as they claimed their fifth home win of the season thanks to a bonus-point victory over Clifton.
Joe Morris, Brad Cook and Sam Portland got Henley’s second half tries after the hosts had trailed by seven points at the break.
Chris Levesley and Charles Hubert crossed in the first period for the visitors while Danny Wells landed two penalties, but that was as good as it got for Clifton.
Cook added to his first half score after Morris cut Clifton’s lead to two points and Portland’s try late on sealed the win for Pete Davies’ men.
Worthing Raiders 40-34 Old Redcliffians
Jack Maslen ran in a hat-trick as Worthing Raiders overcame Old Redcliffians at Roundstone Lane.
After Maslen’s first try was cancelled out by two Ashley Grove penalties and an Ethan Doyle score, Worthing went in front as Maslen grabbed his second before Matt McLean scampered over.

The lead would change hands a couple more times before the break as Maslen’s hat-trick wiped out Craig Owen’s effort.
Sam Hampson’s try extended Worthing’s lead but a score from Christian Gervais brought Old Reds to within six points.
A try from Jack Forrest ultimately secured the victory for the Raiders, but the visitors did grab two bonus points with a late converted try.
Tonbridge Juddians 46-15 Wimbledon
Wimbledon slipped to their 13th straight defeat of the season as they were beaten comprehensively by Tonbridge Juddians at the Slade.
TJs led 22-5 at half-time after scores from Hugo Watson, Murray Galbraith-Lowe and Jon McMahon.
Watson completed his hat-trick after the break while Tom Nicoll and Finlay Coxon-Smith completed the rout for Tonbridge.
Kane Alboni’s effort plus two second half scores is all Wimbledon could muster up and the division’s bottom club now sit 21 points from safety.
Broadstreet 15-27 Barnstaple
Barnstaple produced a gritty display to beat 14-man Broadstreet to claim only their second win away from Pottington Road this season.
Barum have won just three of their last 22 matches on the road and they were 15-7 behind at the break in this contest as Broadstreet ran in two first half scores.
A penalty try before the interval gave Barnstaple a foothold in the game and their chances of coming back into this encounter were strengthened when Street had their blindside flanker sent off.
Steve Perry’s side took full advantage and a flurry of tries, including one from Luke Berry, helped them to victory.
