Ryan Oliver netted a first-half hat-trick on his Boston Town debut - as the 10-man Poachers got Lori Borbely’s managerial sting off to a flier.
Town had Shane Clancy sent off just five minutes into Saturday’s contest.
However, the Poachers showed great spirit to put in a five-star performance.
Oliver, who signed from Spalding United last week, scored a treble.
Tim Lowe and Aaron Eyett - grabbing his fourth goal in three games - rounded things off for Boston.
Michael Byrne had pulled Ar Tran levelin the first half.
The result sees Town move up to 11th in the UCL Premier.
