The Baltimore Ravens, sparked by three touchdown passes from Joe Flacco, edged the San Francisco 49ers 34-31 in Super Bowl 47 after a power outage interrupted the game for 35 minutes Sunday.
The Ravens won their second National Football League title, the 12-year gap since their last crown a Super Bowl record, and gave coach John Harbaugh bragging rights over younger brother Jim, the coach of the 49ers.
Players and a crowd of more than 70,000 spectators were almost left in the dark as a power failure early in the second half at the Louisiana Superdome stadium halted the game with the Ravens leading 28-6.
Ravens quarterback Flacco was named the game's Most Valuable Player after completing 22-of-33 passes for 287 yards. Flacco, who is in the final year of his contract, has thrown 11 touchdowns in the post-season.
"It's unbelievable," Flacco said. "I tell you what -- we didn't make it easy."
Flacco hit Jacoby Jones, Dennis Pitta and Anquan Boldin for touchdowns in a first half that was dominated by the Ravens and Jones returned the kickoff a Super Bowl record 108 yards for a touchdown to open the second half.
The Ravens, whose team of destiny tag grew with every post-season victory, looked like winners in a rout until the 49ers found new life after the power delay to challenge Baltimore.
San Francisco quarterback Colin Kaepernick led a second-half comeback for the 49ers, who scored 17 unanswered points in the third quarter to pull within 28-23.
Kaepernick ran 15 yards for a touchdown with just over 10 minutes remaining in the fourth to cut the Ravens lead to 31-29, but that was as close as the 49ers would come.
Baltimore's defense denied San Francisco on a late-game drive and the Ravens ran down the clock at the end of the game, then surrendered a two-point safety with only four seconds remaining.
One tackle on a free kick later and the Ravens were champions.
During the power outage delay, the players spent the time on the field and the sidelines trying to stay loose by doing warmup exercises, passing balls or working on their kicking technique.
Some players had fun, getting the crowd to start cheering or begin a chant.
Reserve power kept the field from going dark but some scoreboards and escalators stopped working. NFL officials said they are investigating the cause of the power failure.
Jones took a pass from Flacco on a brilliant 56-yard pass and run play with just under two minutes remaining in the second quarter for the Ravens.
Jones fell backwards while making his catch, then rose and scrambled past two San Francisco defenders before diving into the end zone to give the Ravens a 21-3 lead.
Flacco also completed a one-yard pass to Pitta for a touchdown in the second quarter and a 13-yard toss to Boldin to open the scoring on the Ravens' first possession of the game.
Boldin, who caught six passes for 104 yards, outraced 49ers defender Donte Whitner before leaping to snag the Flacco pass for his fourth reception of the playoffs.
