Thornensians came unstuck in the mud at Northallerton last weekend, going down 13-3 against their Yorkshire Three rivals.
The hosts used the conditions to suit their heavy, bulky pack which carried them to victory.
But James Fenwick provided stern resistance and Anthony Bull again excelled in the line out.
Northallerton were on top in the scrums, often wheeling the Thorne pack.
This helped them to two unconverted tries in the first half while they added a penalty in the second, as did Thorne to get off the mark.
Phil Raper added the kick for Thorne while returning prop Mick Holt impressed with an appearance off the bench. Paddy Tigh also added a good performance.
Thorne travel to third placed Goole on Saturday.
The Development XV beat their Goole counterparts 24-12 at Coulman Road last weekend.
Mark Plumber provided sturdy defence and ran in two tries while returning wingman John Williams also crashed over with Conrad Hanson on kicking duty.
The Development side host Hessle Second XV at Coulman Road in a 2.15pm kick off on Saturday.
A pre match lunch will be held on March 5 when Thorne host Hessle. To book contact Ian Wigham on (01302) 845690.
Coulman Road played host for the Yorkshire U15 squad who welcomed representatives from Cardiff Schools, with each side winning a game.
Fantastic work was done by club personnel and volunteers to cater for dozens of players, supporters, officials and parents.
A Yorkshire U14s triangular tournament will be held at Coulman Road this Sunday from 11am.
n THOUGH they had nothing to play for in their final league match of the season, Doncaster Knights will have been disappointed with the manner of the 16-13 defeat to future play off group rivals Cornish Pirates at Castle Park.
Doncaster gave away far too many penalties in the defeat to the Pirates, who they will meet again on March 13 in Cornwall in the opening match of the four team Pool B.
The Knights also face clashes with local rivals Rotherham Titans as well as Bedford Blues.
Director of rugby Lynn Howells will be hoping for an ease in his injury woes ahead of the play off campaign after only being able to name a bare squad of 22 players for Saturday’s visit of the Pirates who drew first blood with centre Tom Luke touching down after five minutes and full-back Rob Cook kicking the conversion.
Doncaster stand-off Christian Lewis-Pratt kicked a penalty, and traded similar kicks with Cook as the score moved from 3-7 to 6-10.
But the Knights gave away too many needless penalties which were punished by Cook, and the South West side led 6-16 with a minute remaining.
No 8 Ed Jackson crashed over and Lewis-Pratt converted to close to within three points, but Doncaster ran out of time and had to be content with a losing bonus point.
The Knights return to British and Irish Cup action this weekend with the trip to Ayr.
Should Doncaster triumph against the Scottish Premier Division side they will progress to the last eight of the competition
