Baltimore, MD (Sports Network) - Turnovers can be the ultimate difference maker.
The Baltimore Ravens scored 17 points off four Houston giveaways and emerged with a 20-13 victory over the Texans in an AFC divisional playoff game Sunday at M&T Bank Stadium.
The Ravens are headed to the AFC championship game for the third time in franchise history and first since the 2008 season. They will travel to Foxboro next Sunday to meet the Patriots, who dismantled Denver on Saturday night in a 45-10 rout.
"This football team won the game no matter what. It wasn't perfect by any stretch, but they found a way to win," said Ravens head coach John Harbaugh.
Joe Flacco threw two first-quarter touchdown passes for Baltimore, which notched its second postseason home win. The AFC North champs' only previous playoff victory at home was a 21-3 wild-card win over Denver on December 31, 2000, the first step on the way to winning Super Bowl XXXV.
Arian Foster had 132 yards on 27 carries for the Texans, who added another item to their list of playoff firsts: a loss.
Rookie Houston quarterback T.J. Yates was picked off three times -- twice by Lardarius Webb, whose second interception led to a 44-yard field goal by Baltimore's Billy Cundiff with 2:52 remaining in the fourth quarter.
Yates started the ensuing drive with completions of 18 and 16 yards to standout wide receiver Andre Johnson, moving the ball to the Baltimore 38. Yates went back to Johnson following the two-minute warning, but Ed Reed came down with his eighth career playoff interception just outside the end zone.
The Ravens were forced to punt, giving Houston one last chance with 45 seconds to play. Baltimore prevailed when Yates' deep pass on fourth down from the Baltimore 43 fell incomplete.
"If we didn't turn it over, it's a different game. We didn't protect the ball," said Texans head coach Gary Kubiak.
Yates echoed his coach's sentiments. "We had a lot of chances but we hurt ourselves with turnovers. Our defense did a great job all game long. We have to protect the ball."
Houston's Neil Rackers kicked a 40-yard field after Danieal Manning returned the game's opening kickoff 60 yards. But the Texans' special teams unit committed a costly mistake after forcing the Ravens to go three-and-out on their first offensive drive.
Return man Jacoby Jones inexplicably attempted to field a punt with a defender on top of him after the ball had bounced off the turf. Jimmy Smith recovered the fumble, setting Baltimore up at the Houston two-yard line.
Flacco quickly capitalized on the turnover with a touchdown toss to tight end Kris Wilson, who didn't have a reception during the regular season.
The Ravens' next drive ended with Cundiff converting a 48-yard field goal.
After both teams went three-and-out, Webb picked off Yates' pass to Johnson on first down at the Houston 34. Five plays later, Flacco hooked up with Anquan Boldin on a 10-yard touchdown, extending Baltimore's lead to 17-3 with 1:08 remaining in a first quarter. Boldin missed the final two games of the regular season following knee surgery.
The Texans battled back in the second quarter behind the legs of Foster, who ran for more yards in the first half (95) than Baltimore had ever allowed in single playoff game (Eddie George had 91 for Tennessee in 2000).
Foster was held to 49 yards on 15 attempts in a Week 6 loss at Baltimore.
Houston's ensuing drive stalled inside the red zone and Rackers connected on a 33-yard field goal.
After the Ravens went three-and-out, Foster began an 86-yard drive by scampering up the left sideline for 28 yards. Houston eventually moved the ball to the Baltimore 17, where Foster made a one-handed catch on a screen and ran for 12 yards on third-and-nine. Three plays later, Foster bulled his way over the goal line from a yard out to trim the Texans' deficit to 17-13 with 4:48 to play.
A scoreless third quarter featured Baltimore running back Ray Rice being stuffed at the Houston one-yard line on fourth down after a 50-yard field goal bid by Rackers came up short.
