One successful Joe Flacco pass got there just in time. The other successful pass from Flacco, Baltimore’s rookie quarterback, fluttered in the air before it was snatched by a receiver.

The last key pass from Flacco required a leap and a catch by tight end Todd Heap for a 23-yard gain.

Three plays. That was really the extent of the Baltimore Ravens’ offense Saturday, but it was enough to squeeze past the error-prone Tennessee Titans, 13-10, in an American Football Conference divisional-round playoff game at LP Field.

The Ravens managed just 212 yards, 51 yards of that total rushing. Flacco completed 11 of 22 passes and found it difficult to find a safe place to place the ball against the Tennessee defense, which was overshadowed in most of the pregame hype by the Baltimore defense.

Flacco completed a 48-yard touchdown pass to Derrick Mason for one score and a 37-yard pass to Mark Clayton when the Titans’ defenders stumbled at the end of the play. That set up a Baltimore field goal for a 10-7 lead.

For most of the game, the Titans’ defense trumped a pile of Tennessee penalties, costly turnovers and an injury to running back Chris Johnson, who had 72 yards rushing in the first half and did not play in the second half.

In addition, the Titans’ defense was slightly wounded, with right end Kyle Vanden Bosch fighting a groin-muscle injury and tackle Albert Haynesworth hobbled by a sprained knee. Vanden Bosch and Haynesworth worked in shifts because of a lack of conditioning from their injuries, but they were effective enough.

The Titans still had end Jevon Kearse at full speed, and the player nicknamed the Freak busted up field or knifed inside to make plays.

Baltimore ran a lot of two-man routes to keep maximum protection for Flacco, but Tennessee countered by pressing Mason and Clayton at the line of scrimmage.

The Ravens’ offensive player with the most success against the Tennessee defense was the player most familiar with the Titans — Mason, who played here for eight seasons.

Tennessee safety Chris Hope was late finding Mason down the right sideline in the first quarter when Mason caught his touchdown pass. Nick Harper, the Titans’ left cornerback, was covering Mason early in the route, but when Mason went deep, he wound up all alone. He caught the pass inside the 10-yard line and scored.

Tennessee made the game tougher than it needed to be with turnovers and penalties (nine for 69 yards in the first half), but the Titans’ defense kept rescuing the home team.

Baltimore had 94 yards in offense in the first half — 48 of them on the pass play to Mason.

Tennessee’s defense continued its sparkling play in the third period. With 4 minutes 40 seconds to play in the third quarter, Baltimore faced third-and-5 at the Titans’ 45.

Mason released inside, but as he reached to grab the ball, Harper yanked the receiver’s arm down and the pass was incomplete. Mason berated the officials, hoping for a penalty, but in the end, it was another key play from the Tennessee defense.

The Titans’ defense rose to the occasion again in the fourth quarter when Alge Crumpler’s fumble ruined a potential Tennessee scoring drive inside the Baltimore 5 with the Ravens leading by 10-7.

The Ravens had to snap the ball close to their own goal line and were stopped on three plays, forcing a punt. The Titans got the ball back at the Baltimore 42 and drove for the tying field goal with 4:23 to play.

But Flacco had that third big play, the 23-yard pass to Heap on third-and-2 from the Baltimore 32. The play carried the ball to the Titans’ 45.

The winning 43-yard field goal from Matt Stover followed with 53 seconds to play, and the Titans lost — despite a dramatic effort from their defense.
