Chesterfield enjoyed Wembley glory for the first time as they beat Swindon to lift the Johnstone's Paint Trophy.
The Spireites had a goal disallowed when Jack Lester slotted in, only for Simon Ford to be adjudged offside.
But the breakthrough came after the interval from an own goal by Swindon's Oliver Risser after Alex Mendy's ball across a crowded box.
After missing an open goal, Craig Westcarr made amends in injury time to seal victory for John Sheridan's men.
After the elation of winning League Two last season, Chesterfield fans have had little to cheer about this term, with their side rooted at the bottom of League One having won just seven times in 38 games.
But the Spireites faithful were in fine voice at the full-time whistle at Wembley after they witnessed a confident, comprehensive display against League Two leaders Swindon.

“I feel desperately sorry for the Swindon fans. They're a club that deserve success. But the Chesterfield players' effort and workrate made it an unbelievable performance. It's just a brilliant day for their supporters. Swindon must now focus on League Two, dominate it and win it”
Paolo di Canio - looking for his first piece of silverware as a manager - was without his captain Paul Caddis and the Robins looked weak without him in the heart of defence.
Chesterfield had the ball in the net early doors but the offside flag was waved when Lester stabbed home after Ford's effort had clouted the bar.
But Swindon found their stride, loan man Lee Holmes looking a constant threat with his blistering pace on the left wing.
His first chance was curled goalwards with his right foot but it took a double deflection off goalkeeper Tommy Lee, who later saved from Holmes' cross shot.
Chesterfield were dealt a massive blow when veteran striker Lester was forced off with a groin injury and struggled to get forward as Swindon continued to push for a goal.
Their best chance came just before half-time when Paul Benson set up Alan Connell but his acrobatic volley went well wide.
The Spireites came out revitalised in the second half and made the breakthrough within 70 seconds. After some tricky work on the wing, Mendy's ball across goal caught Risser unaware and he knocked into his own net.
The goal left Swindon rattled and Chesterfield went out to capitalise on their frailties.
Mendy's overhead kick was tipped over, while a mistake by Alan McCormack let Westcarr run clear, but his weak effort went past the post.
The Robins searched tirelessly for an equaliser and almost found it but Alessandro Cibbocchi's bullet header was pushed over the bar by Lee.
But Westcarr finished the game off in injury time when he beat the offside trap, coolly slotting in to crown Chesterfield's deserved victory.
