Sunderland - Blackpool striker DJ Campbell bagged a double as the Seasiders recorded an impressive 2-0 win against Sunderland on Tuesday.
Campbell struck twice in the second half at the Stadium of Light to lift Ian Holloway's unfashionable side into eighth place.
Only Manchester United had previously won a league game at Sunderland in 2010 and although the visitors had keeper Richard Kingson and the crossbar to thank for their clean sheet, they continue to enjoy a remarkable first season in the Premier League.
Blackpool arrived on Wearside having not played since December 11 following a succession of postponed matches, but there were no signs of rust from Holloway's men.
Sunderland's Asamoah Gyan, who had earlier driven the ball into the side-netting from a tight angle, wastefully scuffed wide from Ahmed Elmohamady's cross with the goal at his mercy in the first half.
But Blackpool, without captain Charlie Adam through suspension, found themselves on the back foot for lengthy periods, gradually worked their way into the game and had chances of their own.
Substitute Matt Phillips, on for the injured Elliot Grandin, beat Danny Welbeck and Phil Bardsley and crossed for Campbell, who made space for himself but couldn't hit the target.
Campbell went much closer seven minutes before the break when he worked himself into a good position and fired a low 20-yard drive just wide.
Blackpool took the lead with 52 minutes gone after the home side went to sleep at a corner.
Neil Eardley was given time and space to collect David Vaughan's short pass and clip in a left-foot cross which Ian Evatt flicked on for Campbell to volley home from close range.
Sunderland piled forward as the clock ran down and Kingson had to pull off a series of saves, denying substitute Steed Malbranque 10 minutes from time and then getting Evatt out of jail after his slip allowed Darren Bent a sight of goal.
With four minutes left, Bent's free-kick hit the crossbar but Campbell completed a miserable afternoon for Sunderland when he added a second from Phillips' inch-perfect cross in stoppage time.
