MANHATTAN, Kansas (Ticker) -- Ell Roberson proved too tough for Oklahoma State.
Roberson passed for 202 yards and two touchdowns and ran for 96 yards and two more scores as No. 23 Kansas State defeated the Cowboys for the ninth straight meeting, 44-9.
"He's a great player and he does a lot," Cowboys linebacker Terrence Robinson said. "We have seen him run a lot against teams - run the ball, run the ball, run the ball. And then all of a sudden he comes out and he starts throwing the ball and throws it well enough to make a lot of plays. It was surprising."
Darren Sproles added 130 yards rushing and one TD as the Wildcats outgained the Cowboys, 499-184, including a 297-40 advantage on the ground.
"I think we played better than what it may have looked like or statistically what it may have said," Wildcats coach Bill Snyder said.
The Wildcats (5-1, 1-1 Big 12 North) produced four first-half touchdowns but led only 25-9 at the break due to two missed extra points and one failed two-point conversion attempt.
But Roberson took over in the second half, scoring on a one-yard run in the third quarter, completing a 46-yard TD toss to James Terry early in the fourth quarter and running it in from 10 yards out with 8:50 to go.
Roberson was 9-of-17 with one interception en route to a season high in passing yards.
"I think we need it because it opens up the running game," Roberson said. "We already know we can run the ball. If we can just get the passing down we will be all right on offense."
"We need to do that every game," said Taco Wallace, who had a career-high 101 receiving yards and one score. "Ell proved he can throw the ball. Without the passing game, you can't run over everybody. We need to air it out sometimes."
Josh Fields went 15-of-38 for 133 yards, one TD and two interceptions for the Cowboys (2-4, 0-2 South).
"When you're under duress, it's pretty tough to put the ball where you want to put it," said Cowboys receiver Rashaun Woods, who had 77 receiving yards and one touchdown. "There were a lot of situations out there where he was running for his life. He just couldn't get the throws that he wanted."
Oklahoma State, which barely lost to No. 2 Texas last week, 17-15, has not beaten Kansas State since 1989.
"It didn't appear to me that (the Cowboy defenders) were playing as all-out as they had been," Oklahoma State coach Les Miles said. "We didn't appear sharp and play with the same intensity we had a week ago."
The Cowboys lost starting running back Seymore Shaw after he gained just four yards on three rushes.
"Shaw broke an ankle or broke a bone in his lower leg, and I don't know the severity at this point," Miles said.
The Wildcats got on the board first on a 38-yard run by Sproles 5:26 into the contest, but Jared Brite's extra-point attempt was blocked. With 7:02 left in the period, Wallace caught a 36-yard TD pass from Roberson but the quarterback's two-point rush was blocked.
Fields got the Cowboys within 12-7 on a 27-yard pass to Woods early in the second quarter before Kansas State added a score on a four-yard run by Ayo Saba. But Joe Rheem's kick was blocked and returned by Darrent Williams for a defensive two-point conversion to make it 18-9.
The Wildcats then pulled away for an eighth consecutive home victory since a loss to Texas A&M last October 20.
"I was pleased with how they approached our practices this week," said Snyder, whose team lost at Colorado last week. "I was pleased with their attitude and I was pleased with their recognition of the need to get better in some areas. I expected them to come and play, and they prepared themselves throughout the course of the week to come and play this game."
