Parkgate knocked holders Sheffield FC out of the Senior Cup, 4-3, following extra-time at Green Lane last night.
Club had come close to taking a fifth minute lead when Ant Lynam saw his shot cleared off the line by John Drennan.
But it was the Koolsport side that broke the deadlock on 12 minutes, Matt Griffin scoring with a far post header after Kier Hannity had clipped the ball back in after a corner had been half cleared.
Lynam levelled direct from a free-kick outside the area that zipped through the defensive wall. However, Parkgate regained the lead five minutes before the break, Luke Fletcher scoring with a first time right footer.
Jamie Hadfield converted a Matt Roney cross to put Sheffield back on level terms once more on 70 minutes only for the Steelmen to go in front once more when Chris Wood knocked in a Danny Cardwell long throw to make it 3-2.
But Sheffield hit back again through Chris Adam eight minutes from time, to take the tie into extra-time.
However, it was Parkgate who went in front for a fourth and final time in the 106th minute with the winner. Substitute Jamie Ghaichem pounced at the far post after Griffin helped on a long throw. Parkgate meet Stocksbridge Park Steels in the final at Hillsborough on May 3
