DALLAS -- The Red River Rivalry quickly turned into a Red River rout on Saturday at the Cotton Bowl.
Oklahoma's offense torched Texas, David Ash and the Longhorns offense struggled to move the ball and the Sooners blew out Texas, 63-21, in the annual battle at the Texas State Fair in front of 92,500.
The Sooners won for the third consecutive time in the series.
How bad was it for Texas' defense?
In the first half, the Sooners turned in both their longest running play and their longest passing play in the more than century-long series.
First, Damien Williams broke off a 95-yard touchdown run late in the first quarter that was helped by a crushing block from wide receiver Kenny Stills near midfield.
Early in the second quarter, Landry Jones hit fullback Trey Millard for a 73-yard gain that set up the third of Blake Bell's four touchdowns in the first half.
During Millard's run, he leaped over Mykkele Thompson and while simultaneously delivering a stiff-arm to Adrian Phillips, taking the ball inside the Longhorns' 5-yard-line.
Millard finished with five catches for a 119 yards.
The Sooners racked up more than 400 yards of offense in the first half.
It wasn't any better for the Longhorns' offense.
The Sooners held Texas to 65 yards and two first downs in the first half, and picked up a safety when Jaydan Bird and Tony Jefferson combined to bring down Joe Bergeron in the end zone.
Both of Texas' first downs in the first half came immediately before the Sooners intercepted passes by Ash.
Texas allowed 407 yards in the first half.
By halftime, when the Sooners led, 36-2, large swaths of fans on Texas' side of the evenly split stadium had cleared out.
About the only positive for the Longhorns while the game was in question came after Oklahoma's first score, when the Longhorns blocked the extra point and Quandre Diggs returned it for a two-point conversion.
Other than that, it was all Oklahoma.
The Sooners, reliant on the pass for success much of the year, set the tone with a run-heavy first drive and kept it up with a steady diet of Williams, the junior college transfer who now has three 100-yard rushing games.
