NORMAN, Okla. (AP) -- DeMarco Murray scored three times to set Oklahoma's career record for touchdowns, Ryan Broyles broke his own mark for receptions in a game and the No. 6 Sooners rolled to a 52-0 victory against Iowa State on Saturday night.
Murray ran for 112 yards and two touchdowns and scored on a 15-yard screen pass to surpass 1969 Heisman Trophy winner Steve Owens' record of 57 touchdowns in his career.

Landry Jones threw for 334 yards and three touchdowns while completing the highest percentage of any Oklahoma quarterback with at least 25 attempts. Broyles finished with 182 yards on 15 catches and one touchdown.

It was the 12th straight win in the series for the Sooners (6-0, 2-0 Big 12), who face a showdown at No. 21 Missouri next Saturday night. The Cyclones (3-4, 1-2) absorbed their second straight blowout against a top 10 team that was off the week before.

The Sooners amassed 672 yards of total offense and never got much of a challenge in a series they've dominated, winning 68 of the 75 games played between the teams. Oklahoma also moved to 12-0 under coach Bob Stoops in the game following Texas.

About the only drama in the second half was whether Murray and Broyles would get their records -- which both did in the third quarter -- and whether defensive captain Travis Lewis would get the shutout he wanted.

The Sooners had allowed most of their early opponents to keep it close, winning four of the first five games by eight points or less. So Lewis said on Monday that his message to the defense was to get the first shutout for a unit that recorded three a season ago.

Grant Mahoney was wide left on a 45-yard field goal and well short on a 50-yard try in the first half, and the Cyclones never got past the Oklahoma 49-yard line after halftime. Backup Jerome Tiller replaced starting quarterback Austen Arnaud on the second drive of the third quarter, but had even less success leading the offense.

Murray passed Owens' mark with a 10-yard TD run in the third quarter, breaking the tackle Leonard Robinson's tackle on his way into the right side of the end zone.

Unlike his other scores, he tucked the ball away in his left arm and took it back to the sideline after celebrating with his teammates. Murray's 10 touchdown catches are the most by a tailback in Sooners history, to go along with 46 rushing TDs and two on kickoff returns.

All of Owens' scores came on run plays, as did each of 1978 Heisman Trophy winner Billy Sims' 53 career TDs.

Murray's totals mark his spot as perhaps the most versatile back in the history of a school where the wishbone once carried Oklahoma to greatness and where Adrian Peterson powered his way to a freshman rushing record before moving on to the NFL.

Jones completed his first 13 passes and 25 of 27 in the first half, only missing on a short pass to freshman Trey Franks and a deep ball intended for Broyles down the left sideline early in the second quarter. After two run plays, Broyles got another chance and dove for a 39-yard TD catch that made it 17-0.

Trey Millard and Murray finished Oklahoma's next two drives by scoring on 1-yard runs to extend the lead to 31 by halftime.

Broyles had two catches on the drive that led to Murray's record-setting touchdown to move past his previous career best -- and the school record -- of 13 against Stanford in last year's Sun Bowl.

Jones ended up completing 30 of 34 passes (88.2 percent). Jason White, the 2003 Heisman Trophy winner, went 29 for 35 (82.9 percent) against Nebraska in 2004.

Alexander Robinson, who missed the second half of the Cyclones' 68-27 loss against Utah last week, started and ran for 39 yards on seven carries.
