Joint-manager Graham Drury was delighted with the way Holbeach United made it five successive league wins.
The Tigers – who head to Oadby Town on Saturday – remain on top of the table with a 100 per cent record.
Drury said: “It was a tough game at Boston and the main thing was how we would bounce back from a defeat in the FA Cup.
“They made us fight really hard again but we responded very well.
“All credit to Boston. They put in a really good performance and Nathan Collins has put together a good side.
“There is a lot of desire in our changing-room. We are on top of the league and we want to stay there.
“The second half showed a different side and sometimes you have got to dig in.
“It was all about the result and we looked a lot stronger at the back.”
