Westcarr and Hughes on target before Bent nets consolation
Goals from Craig Westcarr and Lee Hughes saw Notts County pull off a famous FA Cup victory over Sunderland at the Stadium of Light.
Westcarr put the League One side ahead on five minutes after keeper Simon Mignolet had fumbled the striker's flick into his own net before Hughes then doubled the advantage with 15 minutes to play.
Darren Bent pulled one back for a much-changed Black Cats side from the penalty spot on 81 minutes to set up a nervy finish but Paul Ince's Magpies held on for a shock victory which was little more than they deserved.
Sunderland boss Steve Bruce made wholesale changes for the game, admittedly some of them enforced, with one eye on next Sunday's derby clash with arch-rivals Newcastle.
He made seven changes as he rested keeper Craig Gordon, defenders Phil Bardsley and Titus Bramble and midfielders Jordan Henderson and Ahmed Elmohamady, but still fielded a £23million strike-force in Asamoah Gyan and Bent.
However, it was a measure of how poorly Sunderland played before the break that it was not until the last minute of the first half that either managed a shot, and even then, £13million-plus man Gyan scuffed it wastefully.
The Black Cats were able to create little as a midfield featuring Andy Reid and Jack Colback following their return from loan spells was effectively shackled by Ince's hard-working quartet.
Least effective
But it was at the back where the Premier League side proved least effective, and spectacularly so with just five minutes gone.
Ben Davies' left-wing cross was flicked on by Westcarr and it looked innocuous enough as Mignolet rose to claim it with Hughes making his presence felt.
However, for reasons best known to himself, full-back Kieran Richardson got in on the act and succeeded only in colliding with his own keeper.
The pair looked on in horror as the ball spilled from the Belgian's hands and dropped over the line, sparking mass celebrations among the travelling supporters among a crowd of just 17,582 at the Stadium of Light.
Sunderland's response was laboured as Bruce took up residence in his technical area, but they went close to an equaliser with 28 minutes gone.
Reid embarked upon a powerful run to the edge of the County box and after exchanging passes with Bent, sent a left-foot shot just over the angle of bar and post.
But the Wearsiders' fragility in defence almost cost them once again two minutes later when Magpies skipper Mike Edwards was allowed to meet Davies' free-kick beyond the far post and send a left-foot shot across goal and just wide of the far post.
Made amends
Westcarr might have doubled his tally with four minutes of the half remaining when he curled a right-foot effort towards the bottom corner, but Mignolet made amends for his earlier error with a good save to spare his side further damage.
Gyan should have sent his side in at the break level after Reid forced a pass through to him, but he mishit his shot as keeper Stuart Nelson came to meet him and Krystian Pearce was able to head clear.
Sunderland's response to whatever Bruce said at the break was distinctly lukewarm in the early stages of the second half, and Bruce made his move on the hour when he withdrew Cristian Riveros and Colback and sent on Henderson and Elmohamady.
The newcomers combined to great effect within two minutes for the Egyptian to set up Steed Malbranque, but he sliced his shot horribly wide.
Bent headed wide from a 64th-minute Elmohamady cross and then again from a Richardson's delivery eight minutes later with the Black Cats belatedly building up a head of steam.
But their hopes were dashed 15 minutes from time when Hughes skipped through a flat-footed defence and despite seeing his initial shot saved by Mignolet, thumped the loose ball into the empty net from a tight angle.
Bent gave Sunderland hope when he claimed his 11th goal of the season from the penalty spot after Richard Ravenhill had tripped Reid with nine minutes remaining.
He then headed over in the sixth minute of injury time as there was to be no late rescue act for the Black Cats.
