The 23-year-old struck 14 minutes after the break after Sunderland's record signing Asamoah Gyan had earlier cancelled out Frederic Piquionne's opener for the visitors.

Samir Nasri scored two penalties in extra-time to help Arsenal to a 4-1 victory over north London rivals Tottenham in the third round of the Carling Cup.
Henri Lansbury had given the Gunners the lead in the first half at White Hart Lane, but Robbie Keane equalised just after the interval.
However, Nasri succeeded where Tomas Rosicky had failed at Sunderland on Saturday, firing home two convincing spot-kicks after he had been brought down by Sebastian Bassong and Marouane Chamakh pulled back by Steven Caulker. Andrey Arshavin completed the scoring.
Everton crashed out in London, beaten 4-3 in a penalty shoot-out by League One strugglers Brentford after a 1-1 draw over 90 minutes.
Jermaine Beckford and Phil Jagielka failed from 12 yards for David Moyes' men.
Full-back Seamus Coleman had earlier fired Everton into a sixth-minute lead but the Bees drew level with a header from Gary Alexander in the 41st minute.
Bolton boss Owen Coyle endured a miserable evening on his return to former club Burnley, Wade Elliott scoring the only goal for the home side.
Coyle was predictably abused all night by the Turf Moor faithful, who saw Elliott's 45th-minute volley pushed out by goalkeeper Adam Bogdan only for referee Mark Clattenburg to award the goal on the advice of his linesman.
Birmingham enjoyed a comfortable passage into the next round after scoring three goals in four first-half minutes to beat MK Dons 3-1 at St Andrews.
Alexander Hleb, Nikola Zigic and Craig Gardner put the result beyond doubt by the 28th minute, with Dons substitute Aaron Wilbraham deservedly bagging a late consolation for the League One side.
Tamas Priskin and Gareth McAuley gave Ipswich a 2-1 victory over Millwall at the New Den.
Priskin struck his third goal of the season in the 23rd minute and defender McAuley doubled the lead before the break.
Steve Morison pulled one back in the second half but Ipswich held off a late onslaught to reach the fourth round for the first time in eight years.
Championship outfit Swansea also joined the last-16 line-up as a hat-trick from former Chelsea winger Scott Sinclair accounted for League One pacesetters Peterborough at London Road. Craig Mackail-Smith scored Peterborough's goal in their 3-1 home defeat.
First-half goals from Michael Morrison and Lloyd Dyer saw Leicester advance at the expense of 10-man Portsmouth.
A late Liam Lawrence goal set up a tense finale at Fratton Park following Richard Hughes' straight red card, but Leicester held on.
Headers from Danny Higginbotham and Kenwyne Jones secured Stoke's 2-0 victory over Fulham at the Britannia Stadium.
Higginbotham gave the Potters the lead in the 23rd minute, arriving at the far post to convert Matthew Etherington's corner and Jones wrapped up the win with his third goal in three games 11 minutes from time.
Wolves were given a scare by Notts County but came through 4-2 after extra-time at Molineux.
Former West Brom striker Lee Hughes put Notts County ahead in the 57th minute, but a penalty from Nenad Milijas seven minutes from the end of regulation time forced the extra 30 minutes - after County defender Liam Chilvers had been sent off for hauling back Christophe Berra.
Substitute Steven Fletcher put Wolves ahead for the first time two minutes into the added period, and Kevin Doyle gave them breathing space by making it 3-1.
Kevin Smith replied for County but Doyle scored again with a minute remaining to remove any doubt.
Stamford Bridge - Chelsea
Directions & Car Parking
Leave the M25 at Junction 15 and take the M4 towards London, which then becomes the A4 up to Hammersmith. Carry on over the Hammersmith flyover and after a further one and half miles, take the turning Earls Court. Continue past Earls Court station and down the one way system until you reach the junction with Fulham Road. At this junction, turn right at the traffic lights and after about half a mile, you will see the ground on your right.
A number of local resident schemes are in operation around the ground, so you may well end up having to park some way from the ground itself.
By Train and Tube
The nearest tube station is Fulham Broadway which is on the District Line. Take a tube to Earls Court and if necessary, change for a Wimbledon bound tube. The nearest overground train station is West Brompton, which is served by trains from Clapham Junction (which is in turn served by trains from London Waterloo and Victoria stations). It is around a 15 minute walk to the ground from West Brompton station. Turn right outside the station past the Tournament Pub, then right again into Brompton Cemetery. Walk on through the Cemetery (just follow the crowd) and Stamford Bridge is soon visible to the right. If it is a night game then turn right after the cemetery into Finborough Road. After a half-mile, turn right onto the Fulham Rd. Thanks to Jim Millington for providing the directions.
Away Fans
Away fans are located in the South East corner of the Shed End, rather, where the normal allocation for league games is 3,000 tickets, with fans located in a portion of the upper tier of the Shed End Stand and the whole of the lower tier. If Clubs elect to take only 1,500 tickets then, fans will be located on the East side of the stand in both the upper and lower tiers. For cup games the whole of the Shed End can be allocated. The view from this area of the ground is pretty good and the refreshment areas and concourses were modern and new looking. There are televisions on the concourses, showing amongst other things at half time, highlights from the first half.
On the whole I found Stamford Bridge a pleasurable day out. There was a good atmosphere within the ground and even though there wasn't a lot of space between the home and away fan sections, in didn't feel intimidating. The stewards were pretty laid back. The only 'hassle' I had was trying to get through two lines of stewards to gain entrance to the away turnstiles as they seemed to assume that I was a Chelsea fan and kept ushering me towards the home end. Only after showing my ticket for the away section for a third time did I finally make it inside! I was seated in the upper tier and I found a little difficult to go up and down the steps of the stand as they were quite small and there were steps between each row. Considering that the stand is quite steep then they seemed quite awkward or do you think it may have been something to do with the few beers that I had consumed beforehand?
Where To Drink
The pubs near the ground can be quite partisan, so I would recommend getting a drink somewhere on the journey there. Gordon a visiting Newcastle fan adds 'there are quite a few pubs on the Kings Road that are okay as long as you don't break into a chorus about your team!'. Ross Mooring adds; The best (well, least partisan) pub for away fans is the Slug and Lettuce outside Fulham Broadway train station situated a few minutes walk from the ground. It's an upmarket pub with a good security and police presence outside on matchdays. Very full but rarely any trouble. Away fans though should avoid the Sofa Bar. Alcohol (Budweiser) is available inside the ground but it is a bit pricey, even for Londoners!'.
About a 15 minute walk away from the ground near Parsons Green Tube Station is the White Horse. A large comfortable pub which sells good food and a range of real ales including Harveys Ales from Sussex. To find this pub with the new West Stand behind you turn right (up past where the away coaches are parked) up Fulham Road and into Fulham Broadway, passing the tube station on your right. Continue to follow Fulham Road around to the left and then take a left hand turn into Parsons Green Road. Go under the bridge passing Parsons Tube Station on your right and you will reach the White Horse pub on your left.
Trevor Simpson a visiting Ipswich Town fan adds; 'I have to say, we were very impressed with the White Horse. It is a large roomy place with a good atmosphere and is far enough from the ground not to be over-run by fans. It is still a comfortable walk to the stadium, less than 15 minutes. It is also so easy to get to the pub in the first place, simply get off the tube at Parsons Green and it is about 100 yards away. The food is a bit pricy; on a match-day the only sandwich is a BLT for £5.50. They also have a barbecue going (even in January) and it is £6 for a burger and £5 for a sausage baguette. I had a baguette and it was fine. The biggest plus is the choice of beers, if you are a real ale fan then this pub is a gem'. Alcohol is available inside the stadium, however for certain fixtures the Club opt not to sell any to away supporters, so don't bank on it!
PLEASE NOTE - A Chelsea fan has just imformed us of the following: In your article you mention the ''Slug & Lettuce'' pub for away fans. I have to advise you and your fans that this has been renovated, renamed the King''s Head (its former moniker) and is for HOME fans only.
I would suggest toon fans should try boozers on the King''s Road - as another of your corespondents said, as long as no one ''shows out'' they should be fine.
