Boston Rugby Club’s hopes of doing the double over league leaders Ashby were ended with a 43-17 defeat.
The Blue and Whites were left to rue the opening 20 minutes, where they allowed the home side to amass 15 unanswered points.
Despite a spirited second half performance, the gap proved too difficult to bridge.
Boston knew they would be in for a tough afternoon as the home side sought revenge for their only defeat of the season at the hands of Boston.
Willem Jonker’s side welcomed Will Scupham back from suspension, playing at fly half in a new pairing with debutant scrum half Chris Lomas.
Two tries, one converted, and a penalty saw an early lead established by the hosts, before a penalty saw Boston close the gap.
It was against the run of play that Ashby scored their third try minutes before half time to take a 22-3 lead.
At the interval, coach Jonker made a couple of substitutions, bringing on Alex Kemp for Laurence Moore (Prop) and Travis Cross for Michael Baldwin (wing).
In a reverse of the first half, it was Boston who started strongly, with Scupham scoring their first try after five minutes of pressure.
Boston’s Ross Noble and an Ashby player were both sent to the sin bin midway through the second half, just before Ashby scored again to extend their lead to 10-27.
Dave Cotton-Betteridge scored Boston’s second try, which was converted by Scupham to take the score to 17- 27.
But it was the hosts who finished off the scoring, taking the score to 43-17.
Next week, Boston host Aylestone St James, who sit a place below them in seventh spot in the Midlands 3 East (North) (KO 2.15pm).
BOSTON: Moore, Dowse, Deamer, Enderby, Eldin, Noble, Cotton-Betteridge, Hughes, Lomas, Scupham, Baldwin, J. Brooks, Stokes, Hodgson, Andrew; Replacements: Sharpe , Kemp, Cross.
