Joint-manager Jason Lee praised Boston United as they came from behind to snatch a 2-1 victory at Corby Town in Blue Square Bet North.
Ben Fairclough headed the 93rd-minute winner after Ian Ross had cancelled out Delroy Gordon's opener for the hosts.
Lee told BBC Lincolnshire: "As late as it came, I felt we deserved to win.
"We were excellent from start to finish and to go in a goal down at half-time was a real blow, but we kept pushing and were more than value for our win."
Boston started the stronger side and forced a string of corners, but it was the Steelmen who went ahead against the run of play on 38 minutes from their first corner of the match with Gordon bundling home.
The Pilgrims levelled in the 53rd minute when Ross blasted home a free-kick following a foul on Danny Sleath, and as they pressed for the winner Marc Newsham hit the bar before Fairclough headed home a Conor Marshall cross in added time.
"For the first 35 minutes we dominated," said Lee. "We kept possession and we worked hard and I couldn't see a problem, but then we were sloppy at a corner.
"We went in at half-time disappointed, annoyed and angry and everyone was feeling sorry for themselves but we knew we were more than capable of winning.
"But we got on the ball again and caused them all sorts of problems and on reflection, in terms of possession, corners and shots, it was fully deserved."
