No. 17 Miami 21, No. 8 Oklahoma 20

Miami — After Jacory Harris threw his second interception of the opening minutes, Miami’s sophomore quarterback went to the sideline with a most unusual reaction.

He laughed.

Rattled? Not in the slightest.

Harris settled down, the Miami defense got rolling — and the result was the Hurricanes’ biggest win in years. Javarris James ran for a career-best 150 yards, Harris threw for three scores and No. 17 Miami knocked off No. 8 Oklahoma on Saturday night — in what will join some games from the 1980s as another Hurricanes-Sooners classic.

“Big, huge win for us,” Miami coach Randy Shannon said. “It’s huge.”

With Oklahoma’s reigning Heisman Trophy-winning quarterback Sam Bradford watching from the sideline, still out with a right shoulder injury, Miami (3-1) scored 21 straight points to take control.

And then they held on, running out the final 4 minutes because James — who still beats himself up over a fumble that turned the tide in Miami’s 51-13 loss to the Sooners two years ago — churned up 38 yards against an Oklahoma defense that came into the game as the nation’s best against the run.

Not anymore.

This one almost certainly ended any Sooners national title hopes, too. Landry Jones threw for 188 yards and DeMarco Murray and Chris Brown combined to rush for 151 more for Oklahoma (2-2).

Kansas State 24, Iowa State 23

Kansas City, Mo. — Emmanuel Lamur blocked the extra point after Iowa State’s Austen Arnaud had thrown a 23-yard TD pass with 32 seconds remaining, allowing Kansas State to escape with a wild victory at Arrowhead Stadium.

Five minutes earlier, Grant Gregory, who started in place of Carson Coffman, put Kansas State (3-2, 1-0 Big 12) ahead, 24-17, with a 54-yard touchdown pass to Brandon Banks.

Arkansas 47, Texas A&M 19

Arlington, Texas — Ryan Mallett shook off a slow start and threw four touchdown passes to lead Arkansas to a victory in the revival of their Southwest Conference rivalry.

Hogs fans remained to crank up a loud chant of “S-E-C! S-E-C!” in the final minutes.

Texas Tech 48, New Mexico 28

Lubbock, Texas — Backup quarterback Steven Sheffield threw for 238 yards and three touchdowns to lead Texas Tech.

Taylor Potts, the nation’s leading passer, left the game before halftime after two hard sacks appeared to affect his balance. Officials from Texas Tech (3-2) declined to comment on his injury.

Baylor 31, Kent State 15

Waco, Texas — Third-string quarterback Nick Florence rushed for two touchdowns in his first career start and Baylor won its first game without standout Robert Griffin.

Blake Szymanski, who was expected to start at QB, did not play after missing significant practice time this week because of a bruised shoulder. He got hurt last week in relief of Griffin, who is expected to miss most of the season with an isolated tear to the ACL of his right knee.
