Dunn and Schiavi seal success for Clarets
Two goals in the last four minutes secured Deeping Rangers' place in the semi-final of the Lincolnshire Senior Trophy on Tuesday night.
The Clarets had been kept at bay by a battling Boston Town side despite enjoying the lions share of the possession and creating the better openings.
However, they were awarded a slightly fortuitous penalty late on when Ollie Pinner was adjudged to have handled after going up for a cross with Luke Hunnings.
Henry Dunn calmly dispatched the penalty and, after Boston had seen Lorand Borbely sent off for dissent in the aftermath of the spot kick award, Dan Schiavi sealed their place in the last four where they will meet either Holbeach United or Pinchbeck United.
Deeping manager Michael Goode commented: "I thought we played really well in the first half, but it was just a case of scoring that first goal.
"We just needed that little bit of care and attention in the 18-yard box. Some of the through balls we put in were excellent and the chances were there.
"It was frustrating that we didn't get ourselves one or two goals up because we had a plan of starting strong.
"We started the second half well and again created one or two things, probably from setpieces this time, but you do get a little bit of twitchy when you haven't scored.
"I thought Boston did well. Their keeper has played really well. He's made some good saves and looked solid.
"They can pass and look after the ball and, if they get in the right areas, they can keep it and their shape is good. They were not just hacking it anywhere and giving possession back to us.
"We had to work hard to get the ball back. We've probably got a bit of luck with the penalty, but it's a great finish by Henry and we should have killed the game off in the first half.
"Any cup game is hard, especially after a tough match on Saturday, but we got through it and that's all that matters."
Rangers started the game on the front foot with Dan Jarvis flashing an early shot over while Poachers goalkeeper Travis Portas did well to deny Dunn from close range.
Portas then reacted well to smother a deflected Jack Fryett cross before Dunn blazed over when well placed.
Portas made another top save to thwart Dunn who had raced clear before Scott Mooney dragged a shot wide as the first half finished goalless.
Rangers were again on the offensive in the second period with Michael Simpson glancing an early header wide before Portas produced an excellent fingertip save to turn over Hunnings' well-struck effort at the back post.
The Boston goalkeeper was then smartly across to smother another Jarvis effort before the Poachers applied some pressure of their own without troubling home custodian Lewis Elsom as Pinner shot over from the edge of the box.
The deadlock was finally broken after 86 minutes when Pinner went up for a header with Hunnings following a corner into the box and was adjudged to have handled.
Dunn struck home the spot kick with Boston then being reduced to 10 men as Borbely was dismissed for dissent.
Schiavi then wrapped up the success after being teed up by a strong run from Dunn and slotting home a calm finish past Portas.
