Boston Rugby Club fought back from 21-7 down to earn revenge at the expense of Southwell.
In a hard-fought encounter, the Blue and Whites got one over the side who had beaten them 19-0 in the reverse fixture earlier this season.
And that was enough for Willem Jonker’s men to move up to sixth in the Midlands 3 East (North) standings.
Boston faced Southwell on a Boardsides pitch which - by the end of the game - looked more suited to mud wrestling.
The home side were up for the challenge and they started brightly, an interception and try from winger Mark Hodgson being converted by Tom Brooks,
However, this was a short-lived lead as the next 15 minutes of the game belonged to Southwell, who scored three converted tries with quick footwork, together with assistance from Boston’s mistakes, on a rapidly deteriorating pitch.
But trailing 21-7 saw Boston up their game, using their forwards to great effect.
They continued to pressurise their opponents as players from both teams were diving on a very slippery ball.
Prop Joe Deamer broke through traffic to score the first of the Blue and Whites’ comeback tries, before Alex Kemp picked up a loose ball from seven metres out and bulldozed his way over the line.
Brooks converted, bringing Boston to within two points of their rivals.
Southwell scored what was to be their last try, which was converted to give them a 28-19 lead.
With just a few minutes left until half time, Boston scored from a lineout just outside their opponents’ 22 metre line.
They gathered in at speed for what is fast becoming a trademark rolling maul, powering their way forward for scrum half Marc Miles to score the first of his brace of tries for the day.
The conversion by Brooks saw Boston go in at the interval 28-26 behind.
The second half was scintillating stuff, keeping the spectators on the edge of their seats.
Both teams looked to kick in order to gain territorial advantage as the elements were taking their toll.
Tom Andrews was playing particularly well at full back for Boston, catching and kicking well considering the poor conditions.
It took Boston 15 minutes from the re-start to get on the scoreboard again, with a lineout earned from a kick towards touch being juggled by an opposition player.
Again Boston used a rolling maul as Miles scored his second try of the game.
Boston continued to exert pressure through their forwards, as Southwell battled to break out of their own 22 metre area.
Liam Smith had the final say, scoring Boston’s last try of the game to wrap things up 36-28.
