NORMAN, Okla. (AP) Landry Jones threw for 291 yards and three touchdowns, and No. 10 Oklahoma scored on a kickoff return and a punt return in the same game for the first time in school history while clobbering Kansas 52-7 on Saturday night.
Justin Brown made up for a lost fumble on his previous punt return by running his next chance back 90 yards and diving at the pylon for the score. Roy Finch then opened the second half with a 100-yard runback to stretch the lead to 45-0.
The Brown-Finch combo marked the first time the Sooners (5-1, 3-1 Big 12) have had two plays at least 90 yards long in the same game.
James Sims scored on a shutout-preventing touchdown run in the fourth quarter for Kansas (1-6, 0-4), which never presented much of a challenge while losing its 16th straight conference game and 27th out of the last 28.
The Sooners' first-team defense hasn't given up a point in two straight weeks heading into next Saturday night's showdown against No. 5 Notre Dame on Owen Field.
For their part, Jones and the first-team offense scored on their first six possessions - settling for Michael Hunnicutt's 37-yard field goal on their first drive and then scoring touchdowns on the next five.
The streak was finally broken up in the third quarter, after Jones was called for intentional grounding to set up a second-and-26 hole that proved too much to overcome. That ended up being the final series for the starters, who left with a 52-0 lead after just 46 offensive snaps.
Brown and Finch helped that total with their unique double dip. Brown provided the Sooners' first punt-return score since Ryan Broyles did it in 2009, and it had been an even longer drought on kickoff returns - since DeMarco Murray's score against Baylor in 2007.
Oklahoma improved to 14-0 under coach Bob Stoops in games that immediately follow the Red River Rivalry against Texas.
Kansas went with Michael Cummings as its starting quarterback, after he'd been at the helm as the Jayhawks rallied for 14 straight points and had the ball with a chance to go ahead in the fourth quarter of a 20-14 loss to Oklahoma State last week.
He and Dayne Crist, who'd been the starter the rest of the season, were equally ineffective and broke a string in which the Jayhawks had at least been competitive through halftime in each game under first-year coach Charlie Weis.
Crist fumbled away an early opportunity for the Jayhawks to keep it interesting, after Brown fumbled on a punt return and Kansas' Josh Ford scooped it up at the 11-yard line. Crist was off-target on a first-down swing pass to Tre' Parmalee, forcing him to fall down with no one around him in the flat, then threw incomplete into the end zone before Tom Wort sacked him and knocked the ball free.
Defensive tackle Casey Walker picked it up and rumbled 45 yards to give the Sooners a short field for a drive that finished with Blake Bell's 1-yard touchdown run for a 17-0 run.
Cummings replaced Crist on the next ill-fated drive, with Brown weaving from left to right and then diving for the pylon on his punt return TD. Cummings then threw an interception to end the Jayhawks' next possession and create another short field for Oklahoma.
A 4-yard touchdown run by Damien Williams and Jones' 9-yard scoring pass to Sterling Shepard extended the lead to 38-0 by halftime, putting the Sooners well on their way to an eighth straight win in the series.
