STILLWATER, Oklahoma (Ticker) -- The tandem of Josh Fields to Rashaun Woods again spoiled any hopes Oklahoma had of playing for the national championship.
Fields threw three of his four touchdown passes to Woods as Oklahoma State built a 22-point halftime lead and went on to a 38-28 victory over the fourth-ranked Sooners.
Oklahoma (10-2, 6-2) already had clinched the Big 12 Conference South Division title and will play Colorado for the league crown next Saturday in Houston. But the Sooners were third in the latest Bowl Championship Series standings and had been the frontrunner to gain a berth in the Fiesta Bowl against Ohio State should top-ranked Miami lose next week to Virginia Tech.
"I told our players leaving the locker room that a year's work for us doesn't go out the window in one game," Oklahoma coach Bob Stoops said. "We will take our lumps from this, shake it off, and get ourselves in position to win a championship against a very good football team with Colorado."
Those hopes evaporated on Saturday and the Cowboys (7-5, 4-4) again were the culprits. The Sooners were in the national title chase last season before Fields threw a game-winning touchdown pass to Woods with 1:36 remaining to give the Cowboys a 16-13 win.
A year later, it wasn't nearly as close as Oklahoma need a late rally just to make the score respectable. Fields threw three touchdown passes to Woods to help the Cowboys take a 28-6 lead at halftime.
"As far as next year, I don't think that this should be considered an upset, but this year maybe," Fields said. "Next year I think they will start looking at us as their rivals. Hopefully we have gotten in that category."
Fields completed 18-of-27 passes for a career-best 357 yards and was not intercepted. Woods caught six passes for a school-record 226 yards and Tatum Bell carried 22 times for 106 yards to help the Cowboys collect 506 yards.
Under second-year coach Les Miles, Oklahoma State closed the regular season with three straight wins and is assured of its best season since an 8-4 mark in 1997. Miles twice was doused with ice water after the game and Cowboys fans celebrated a win over their intrastate rivals by tearing down the goal posts.
"They keep getting better week after week," Miles said. "In the two years we've been here, this football team gets better and better. At the back end of the season, we are playing our best football."
The win should not come as a complete surprise since the Cowboys have won four of the last six meetings. Oklahoma leads the series, 74-16-7.
Oklahoma lost control of its destiny in the national championship chase with a 30-26 loss to Texas A&M in which freshman quarterback Reggie McNeal had a big day. On Saturday, it was Fields who shredded the normally strong Sooner secondary. Woods said they learned plenty about the Sooners by looking at film during the week.
"It really started Monday by watching film and catching on to the tendencies that the secondary had," Woods said. "If you catch on to those tendencies and take advantage of them you have a chance. (Their) defensive backs are known for sitting on short passes and when they do that they are really set up for the double move."
The Cowboys drove 64 yards in seven plays for a touchdown on their first possession and took advantage of a lucky bounce. Seymore Shaw fumbled on the one-yard line and John Lewis recovered and went into the end zone.
Fields threw the first of his TD strikes to Woods, a 41-yarder, to make it 14-0 after one quarter.
The Sooners cut the lead to 14-6 on a one-yard TD run by Kejuan Jones on the the first play of the second quarter. But Oklahoma State struck back on its next possession with a 60-yard TD pass from Fields to Woods.
"We didn't put pressure on Fields. We got outplayed the whole game," Oklahoma defensive end Jimmy Wilkerson said.
The Oklahoma secondary continued to have no answer for Fields, who completed a 58-yard pass to Billy Bajema and followed two plays later with a 13-yard TD pass to Woods to make it 28-6 at halftime.
The lead grew to 35-6 early in the third quarter when Fields completed a 13-yard touchdown pass to Charlie Johnson.
The Sooners finally showed some life later in the quarter when Nate Hybl threw a 26-yard TD pass to Brandon Jones.
Trent Smith caught TD passes of 13 and 40 yards from Hybl in the fourth quarter. Hybl completed 25-of-38 passes for 211 yards and Quentin Griffin carried 16 times for 102 yards.
Luke Phillips kicked a 40-yard field goal for Oklahoma State in the fourth quarter to make it 38-21.
