DALLAS (AP) - Vince Young and the Texas Longhorns are headed home from the State Fair with the prize that's eluded them for five years: A victory over Oklahoma.

Showing the poise and leadership he's developed since a miserable performance against the Sooners last year, Young threw for three touchdowns in guiding No. 2 Texas to a 45-12 victory Saturday.

The Longhorns (5-0, 2-0 Big 12) convincingly ended one of the most dominant runs in the 100-game series between the Red River rivals and salvaged the reputation of coach Mack Brown.

The orange-clad throng that filled the Texas half of the Cotton Bowl savored every second - and even for a long time after the postgame rendition of the ''Eyes of Texas.'' Several thousand remained inside the stadium rather than heading out to the fairgrounds outside.

The Sooners (2-3, 1-1) came in not only riding their longest series winning streak since the 1950s, they'd outscored the Longhorns 189-54 along the way, leaving the impression that Oklahoma's Bob Stoops was outcoaching Brown. Even with victories over Michigan in the Rose Bowl and at Ohio State earlier this season, Brown still had something to prove in this game.

The proof came right away.

Young led an 82-yard touchdown drive on the opening series that put Texas ahead for good. Although Oklahoma got within 7-6, freshman Jamaal Charles answered with an 80-yard touchdown run on the Longhorns' next snap and the rout was on, especially after an interception by Oklahoma was erased because of a questionable pass interference penalty.

Texas ended up stretching the lead on that drive and pushed it to 24-6 at halftime when Young and Billy Pittman connected on a 64-yard touchdown pass with 17 seconds left in the second quarter. They hooked up again with a 27-yarder in the third quarter.

Young finished 14-of-17 for 241 yards with no interceptions and ran for 45 yards. Charles had 116 yards on nine carries, then left with an injury in the third quarter. Pittman caught four passes for 100 yards and Selvin Young had 45 yards rushing and a touchdown. Ramonce Taylor caught Texas' first TD pass.

The Sooners were stymied from the start because star running back Adrian Peterson had a sprained ankle that limited him to a handful of plays. That put the offense in the hands of freshman quarterback Rhett Bomar , and it was too much for him to handle.

Oklahoma didn't have a play go longer than 9 yards until there was 12:04 left in the game and Texas already was ahead 38-6. After capping that drive with a 15-yard touchdown pass, his next series ended with him fumbling and the Longhorns returning it 67 yards for the kind of pour-it-on touchdown the Sooners have rung up on them the last five years.

Bomar was 12-of-33 for 94 yards and an interception. Peterson, who had 225 yards against Texas last year, ran three times for 10 yards and the Sooners ran for only 77 yards.

With this losing streak buried, Texas can now focus on trying to win its first national title since 1969. The Longhorns haven't come out of the Oklahoma game with a perfect record since 1983, when they ended up going 11-0 before blowing a chance at finishing No. 1 by losing to Georgia in the Cotton Bowl.

The Longhorns haven't lost since falling 12-0 to the Sooners last year.
