Boston Rugby Club’s Colts were beaten heavily by Spalding, going down 55-22.
The game suddenly burst into life as Spalding found some space wide out on the right to score a converted try.
A second try followed shortly after as the big Spalding front row made Boston work hard to secure any possession.
But from a long ball in the line-out, scrum-half Herbie Laidlaw broke through the Spalding line to feed Chambers.
As he was hauled down he found Ayo Adenaike, who scored the try which Matt Bray converted.
After the break Spalding upped the tempo, starting to use their big forwards to drive into the heart of the Boston defence and provide their backs with space and time and plenty of possession.
The gaps started to appear and Spalding ran in four tries in quick succession as their confidence grew.
After a long period of heavy tackling in defence without getting their hands on the ball, Boston eventually started to get some possession in the loose and gain some territory.
A strong run from flanker James Bentley saw him crash over the line for a try and then Bray kicked a penalty.
Any thoughts that Boston were back in the game were quickly extinguished as Spalding re-grouped to score their seventh try. Despite Bentley crossing the line for his second try, Spalding finished the game off with a flurry of points to leave Boston rueing their heaviest defeat of the season.
Iain Borley was Boston’s man of the match.
