Sometimes fortune shines on you, and you just have to accept it and move on.

Oklahoma State survived three second-half turnovers to escape Kansas State with a 43-37 victory in front of 52,450 fans on Saturday at Bill Snyder Family Stadium. It was the second time in as many years that the Cowboys scored in the final two minutes to knock off the Wildcats.

"We really didn't play that well," Oklahoma State coach Mike Gundy said. "Kansas State is famous for stealing yards on special teams and penalties. When you're on the road and give up that many yards rushing and three turnovers, you usually lose the game."

Chris Carson's 17-yard touchdown run with 1:46 left gave the No. 18 Cowboys the winning margin. K-State's final drive got to Oklahoma State to the 3-yard line in the final seconds, but the Wildcats couldn't punch it in.

Last season, the Cowboys kicked a 37-yard field goal with 32 seconds left to win 36-34. It was another frustrating loss for Kansas State.

"We were good, just not good enough," Wildcats offensive tackle Dalton Risner said after the game. "We've got to be able to finish the game."

Mason Rudolph completed 29 of 38 passes for 457 yards and five touchdowns for Oklahoma State (7-2, 5-1 in the Big 12).

"(Rudolph) was pretty decent, which we knew," Kansas State coach Bill Snyder said. "He played well, and he scrambled well. He made some plays on the scramble."

Jess Ertz rushed for a career-high 153 yards and three touchdowns for K-State (5-4, 3-3).

"We ran the ball well," Snyder said. "Got to be able to throw the ball too. We didn't throw the ball very well today."

Kansas State took advantage of the second of three second-half turnovers.

Barry Sanders Jr. fumbled a punt and the Wildcats recovered at the Oklahoma State 39. A fake field goal yielded nothing, but on the second play, Rudolph overthrew James Washington. Duke Shelley picked it off at the 29 and rambled through traffic to the end zone.

It was the 105th non-offensive touchdown for the Wildcats since 1999, most in the nation by a sizable margin.

Oklahoma State's offense stalled just past midfield, and Zach Sinor's punt was deflected. Kansas State took over at its 38-yard line. Six plays later -- five of them runs -- Ertz ran it in from the 2-yard line and Wildcats had a 30-21 lead.

The Cowboys answered with a 75-yard drive that took less than two minutes, capped by a 34-yard pass from Rudolph to Austin Hayes. The third quarter ended with K-State holding a 30-28 edge.

Kansas State answered once again, as Ertz bulled his way for the final yard, his third rushing touchdown of the game, and the Wildcats led 37-28.

On the ensuing drive, Rudolph lofted a pass to Jhajuan Seales, but D.J. Reed picked it off at the K-State 32.

"Last year I might have faltered a little bit (after two interceptions)," Rudolph said. "I kept playing through."

The Wildcats used 3:11 and then pinned the Cowboys at their own 8-yard line. After a 10-yard gain, Rudolph hit Washington in stride for an 82-yard touchdown pass play to get the Cowboys within two points.

"I was real surprised Washington was able to get behind the K-State defense," Gundy said. "I said the play call wouldn't work. I had to turn off my headset because (the OSU coaches) were giving it to me."

Nursing a two-point lead, Kansas State gained nine yards, but Snyder decided not to go for a fourth down and less than a yard.

"I didn't want to," was his terse answer when I asked why he didn't try to gain the yard. "(It would) put our defense in a bad spot."

The punt gave Oklahoma State the ball on its 20 with 5:35 remaining. An 80-yard drive that used nearly four minutes gave the Cowboys the winning score on Carson's run.

K-State opened a 13-lead in the first half, but saw the Cowboys answer quickly. The Wildcats' first drive consisted of 11 runs and no passes.

The Wildcats extended the lead to 13-0 with a six-play, 63-yard drive, capped by a 10-yard run by Winston Dimel.

But the momentum was short-lived.

Oklahoma State cut the lead to 13-7 on a 12-yard touchdown pass from Rudolph to Jalen McClesey. After a K-State punt, the up-tempo Cowboys' offense went 80 yards on five plays, capped by a 54-yard scoring pass from Rudolph to wide-open tight end Blake Jarwin.

Following a K-State field goal, Oklahoma State answered again.

Rudolph connected with James Washington in the back of the end zone to cap a nine-play, 75-yard drive that took only 3:35 and gave Oklahoma State a 21-16 lead.

NOTES: Kansas State wore an alternative look for only the second time since Bill Snyder took over as head coach before the 1989 season. The only other time was on Fort Riley Day in 2013, when the PowerCat symbol on the helmets was in camouflage. The Wildcats' helmets were camouflaged white instead of the traditional silver base. They also wore white shoes, instead of the traditional black. Saturday was Fort Riley Day at Bill Snyder Family Stadium. Fort Riley is a large Army base 20 miles west of the stadium. ... Oklahoma State came into the game with a 38-24 lead in the series, but the teams had had split their previous 12 games in the Big 12. The home team had won 10 of the 12 games, including the last five heading, before Saturday.
