Defending national champion Ohio State needed overtime, but came away with a slim 16-13 victory over 10th-ranked Purdue in U.S. college football's top match-up.

The game ended Saturday, when Purdue's kicker, Ben Jones, missed a 36-yard field goal attempt, minutes after Ohio State took the lead with its own field goal from the same distance. The Purdue Boilermakers nearly blocked that game-winning kick.

On the last play of regulation time, Purdue blocked a 41-yard attempt that would have won the game for Ohio State. The low-scoring contest was the third time this season the Buckeyes have won a game without the offense scoring a touchdown.

The Buckeyes' victory sets up a key contest next week between long-time rivals Ohio State and fifth-ranked Michigan, after the Wolverines crushed the Northwestern Wildcats 41-10.

Meanwhile, number one Oklahoma and number two Southern California posted wins to remain on pace to meet for the national championship in January.

The Oklahoma Sooners cruised past the overmatched Baylor Bears 41-3. Oklahoma has not given up a touchdown in three straight games.

Southern California crushed Arizona 45-0. Wide receiver Mike Williams caught three touchdown passes for Southern Cal, tying a school record.

In an exciting contest, number seven Texas scored a touchdown with 46 seconds left in the fourth quarter to edge cross-state rival Texas Tech 43-40. Texas Tech missed what would have been a game tying field goal as time ran out.

Other top-10 winners were number three Louisiana State University, along with Georgia, Washington State, Tennessee and Texas Christian University.

Leon Washington's 12-yard touchdown run lifted Florida State past North Carolina State 50-44 in double-overtime. The win wrapped up the Seminoles' 11th Atlantic Coast Conference title in 12 years. The Seminoles dropped out of the top-10 last week after being upset by unranked Clemson.

Number 12 Virginia Tech escaped with an overtime 24-23 victory when Temple missed a game-tying extra point after a touchdown.
