MANHATTAN, Kan. -- Kansas State took the ball away from No. 24 Oklahoma State five times to improve remain undefeated with a 44-30 victory Saturday night.
The Wildcats (9-0, 6-0 in the Big 12) should hold their No. 2 ranking in the BCS standings after No. 1 Alabama beat No. 5 LSU 21-17 on Saturday.
Allen Chapman had three interceptions, including a pick-six to give K-State a 31-17 lead at the half. He also snuffed out Oklahoma State's final threat with an interception in the end zone with 2:06 remaining.
The final turnover, Wes Lunt's third interception on the opening possession of the second half, knocked Lunt from the game with an undisclosed injury. Lunt finished the game 11-of-20 for 184 yards and one touchdown, plus the three picks.
Kansas State was fifth in the FBS with a plus-15 turnover margin coming into the game, while Oklahoma State (5-3, 3-2) was ranked 94th at minus-2.
K-State quarterback Collin Klein once again was nearly perfect, finishing the game 16-of-22 for 245 yards. He also had 64 yards on 17 carries, plus a touchdown on the ground. But he too left the game early in the third quarter and was replaced by redshirt freshman Daniel Sams. There was no obvious injury, but he remained on the sideline without his helmet for the remainder of the game.
As has been the case several times this year, Kansas State gave up the first points of the game. Lunt hit Austin Hays for a 54-yard touchdown pass up the middle to cap an 80-yard drive on Oklahoma State's first possession to give the Cowboys a 7-0 lead. It was longest scoring play Kansas State has given up this year, and it was the fifth time this season that the Wildcats have given up the first points in the contest.
But each time, the Wildcats answered with a score of their own -- three of four times with touchdowns -- and this was no different. John Hubert outraced the defense to the front corner of the end zone to score from inside the 1-yard line for a tying touchdown. The key play on the drive was a 50-yard fade pass from Klein to Tyler Lockett to set up the Wildcats at the OSU 7-yard line.
After Kansas State forced Oklahoma State to punt, the Wildcats rattled off an 11-play drive that ended with an Anthony Cantele 23-yard field goal.
Travis Britz then forced a fumble by OSU's Joseph Randle, and it was recovered by Ty Zimmerman on the Cowboys' 29-yard line. Hubert scored his second touchdown on a read-option play from the OSU 5-yard line, and the Wildcats held a 17-7 lead.
Oklahoma State moved quickly down the field and Quinn Sharp connected on a 25-yard field goal to cut the lead to 17-10.
Lockett electrified the crowd with a 100-yard touchdown on the ensuing kickoff. He took the ball at his own goal line and started up the right side. A quick veer to his left opened up a gaping hole and he raced untouched to the end zone.
But Oklahoma State answered right away. Kicking away from Justin Gilbert, who returned an earlier kickoff 41 yards, Cantele kicked it short. Desmond Roland caught it at the 20 and went 80 yards untouched for the score.
Both offenses took a short break by trading punts before Chapman stepped in front of a Lunt pass and raced 29 yards untouched down the left sideline for a touchdown and the final points of the half.
Oklahoma State, which came into the game leading the FBS with 586.1 yards of offense per game, was marching again, but Chapman picked off his second pass in less than two minutes with an acrobatic catch along the sideline with 56 seconds left in the half. Klein's heave to Tramaine Thompson at the end of the half made only the 4-yard line and the half was done.
Oklahoma State was marching on its opening possession of the second half, but Lunt threw his third pick, this one made by Nigel Malone at the K-State 7. Kansas State responded with a 93-yard drive, capped by Klein's 1-yard run.
Clint Chelf replaced Lunt and moved the Cowboys down the field, but they stalled at the 25-yard line. They settled for a 43-yard field goal by Sharp.
After a short punt by Sharp, K-State took over at the OSU 38. But the Wildcats could move just 18 yards and settled for a 37-yard field goal by Cantele.
Chelf then led an 80-yard drive in 1:44 to cut the lead to 41-27. He was 4-of-5 for 73 yards on the drive, including a 13-yard touchdown pass to Charlie Moore.
But the Kansas State return game struck again. Thompson returned the ensuing kickoff 60 yards to the Oklahoma State 33. Oklahoma State's defense held and the Wildcats settled for another Cantele field goal, this one from 40 yards.
Sharp added a 28-yard field goal to cut the lead to 44-30 early in the fourth quarter.
NOTES: Kansas State is 158-5 under Bill Snyder when leading at the half. ... K-State remains the least-penalized team in the FBS. The Wildcats had four penalties for 26 yards, giving them 33 for 259 yards for the season.
