Local boy Jacoby Jones scored two touchdowns, including a 108-yard kick return, as the Baltimore Ravens held off a heroic San Francisco 49ers fightback in one of the most eventful Super Bowls in recent memory at the Superdome, running out 34-31 winners.
Ravens quarterback Joe Flacco threw for three touchdowns, including a 56-yard pass for New Orleans native Jones, as the Ravens established a 28-6 lead - before a power outage caused a break in play during the third quarter which lasted more than half an hour.
The 49ers were transformed when play resumed and quarterback Colin Kaepernick, who had suffered a difficult start to the game, led the fightback, passing for a TD and running for another in a 23-3 run which put the 49ers tantalisingly close.
No team in Super Bowl history had ever come back from more than 10 points down to win, though, and that record remained as the Ravens defence stood firm.
Flacco, who threw for 287 yards in total and was voted MVP, got the ball rolling on Baltimore's first possession, nailing a 13-yard pass on the third and four for wide receiver Anquan Boldin to make a routine catch.
David Akers pulled three points back with a field goal, but it could have been better for the 49ers as Kaepernick's throw to Michael Crabtree for what should have been a touchdown was too high.
Flacco made them pay early in the second as he picked out Dennis Pitta with a one-yard TD pass, while his opposite number struggled - Kaepernick threw the first ever interception by a 49ers quarterback at a Super Bowl into the hands of Ed Reed.
But it was two plays from Jones either side of Beyonce's half-time show that really sealed the Ravens' fate. First he got on the end of a 56-yard pass from Flacco with a tumbling catch, before getting back to his feet and making it to the end zone. Then just seconds after the half-time break, Jones caught the ball at the back of San Francisco's end zone and ran the length of the field for his second touchdown and a 28-6 lead.
The run was initially measured at 109 yards, which would have been the longest kick return in NFL history, but was later scaled down to 108 yards by the NFL, tying the record mark.
A Tucker field goal made it 34-29 and the 49ers knew they would need a touchdown if they were to complete their comeback. But the Ravens defence held firm, conceding two points late on via a safety as they ran down the clock, and Baltimore claimed Vince Lombardi Trophy.
