LSU 16, Alabama 13

Alabama's defense couldn't bail out the fourth-ranked Crimson Tide this time -- or rescue its national title hopes.

JaMarcus Russell kept No. 5 LSU's own championship aspirations alive by hitting Dwayne Bowe in the end zone for an 11-yard touchdown in overtime, lifting the Tigers to a 16-13 victory on Saturday.

Russell hit Justin Vincent on a swing pass for 10 yards to open the possession after Alabama (9-1, 6-1 Southeastern Conference) had to settle for a field goal. Then the LSU quarterback was stopped for no gain when he couldn't find an open receiver against the nation's top scoring defense.

A reverse to Xavier Carter went for four yards, forcing a third and six. Russell rolled right and threw a strike over the middle to Bowe to punctuate an up-and-down day mostly dominated by the defenses.

The LSU players swarmed to the end zone while the Tide fans mostly remained in their seats, stunned by the sudden end to their surprising run at perfection.

LSU (8-1, 5-1) won it without having to turn to place kicker Chris Jackson, who had already missed three of his four long field goal attempts.

Alabama opened overtime much the same way as most of the team's second-half possessions: going nowhere.

The Tide opened with a five-yard penalty on first down and then failed to convert on third and two. Croyle rolled right under pressure and couldn't complete it to tailback Kenneth Darby.

Alabama had to settle for Jamie Christensen's 35-yard field goal.

The Tigers seized control of the SEC West with the win, their fourth in five attempts over ranked teams. They likely need victories over Mississippi and Arkansas to lock it up in the coming weeks.

They were ranked seventh in the Bowl Championship Series ratings entering the game, and still can hold out hope for a spot in the national title game.

LSU has won five of the past six meetings with Alabama, which had already beaten two ranked teams at home this season. This was the first time the Tigers had played in a regular season game featuring two top five teams since 1959.

It was the first top five matchup ever at Bryant-Denny Stadium, since Alabama had played many of its biggest games over the years in Birmingham.

The Tigers had their chances in the fourth quarter against the nation's stingiest defense, forcing Alabama to punt from its end zone on consecutive drives. But Jackson narrowly missed wide left on a 47-yard field goal and then pushed a 49-yarder right of the goal post with 54 seconds left.

He had also missed a 43-yarder in the first half.
