WACO, Texas (AP) -- Without the prospect of a bowl game or even a winning record, Baylor still found plenty of motivation for the season finale.

"We still had the goal of winning a second conference game," running back Paul Mosley said. "And our motto was if we can't go, they can't go, keep them from going to a bowl game as well."

Oklahoma State could have remained bowl eligible with a win.

Mosley had three 1-yard touchdown runs and Collin Allred returned an interception for a score in a season-ending 44-34 victory over Oklahoma State on Saturday that gave Baylor (5-6, 2-6 Big 12) more than one Big 12 victory in a season for the first time.

"There's a lot of monkeys hanging in my office," coach Guy Morriss said.

By ending Morriss' third season with five wins, the Bears had their most since going 7-4 in 1995, their last winning season and a year after their last bowl appearance. Baylor had won three games in each of the last four seasons.

"I have mixed feelings. We really wanted to get in a bowl, but this is a lot of positive we can build off," he said. "I'm happy we won, but I'm disappointed overall."

Baylor ended a five-game losing streak but is still just 8-72 in the Big 12 since the league's inception 10 seasons ago. That includes a 29-game losing streak from 1998-2002, and nine straight conference losses against Oklahoma State (4-6, 1-6) before Saturday.

The Bears built a 38-0 lead in the first half, when Oklahoma State had five of its eight turnovers and a penalty that wiped out a 95-yard kickoff return.

"We were flat," first-year coach Mike Gundy said.

"We under rated Baylor as a team and they came out and showed us they were here to win," defensive end Jerry Don Bray said. "It's extremely disappointing because this is a game we really felt like we could come on the road and take to keep our bowl hopes alive."

After an upset over Texas Tech last week, Oklahoma State could have earned a bowl berth with wins over Baylor and Oklahoma. Now, all the Cowboys have on the line in their season finale is state bragging rights.

Mosley's third TD run made it 28-0 early in the second quarter, coming on the first play after Jamaal Harper intercepted a pass by Bobby Reid and returned it 15 yards.

Daniel McLemore returned the ensuing kickoff 95 yards, but the touchdown was erased by a holding penalty and the ball taken back to the Cowboys 14. Al Pena replaced Reid and his pass on the first play was intercepted by Allred and returned 25 yards. It was the first career interception for the linebacker, one of 19 Baylor seniors playing in their last game.

"We just came out with great intensity," safety Willie Andrews said. "When things started going good, it was a snowball effect. They came out lackadaisical. I think they were waiting for us to give it to them, but we went out there and took it from them."

Pena finished 25-of-42 for 351 yards and four touchdowns, two in the game's final minute, and two interceptions. D'Juan Woods had 10 catches for 186 yards and two TDs.

Reid finished 4-of-8 for 32 yards and two interceptions.

Shawn Bell was 22-of-35 for 272 yards and a 36-yard TD to Shaun Rochon (seven catches for 95 yards) in his return as Baylor's starting quarterback. Bell started the first eight games before Terrance Parks took over the last two.

Parks completed 19-of-44 passes (43 percent) for 153 yards with three interceptions in his two starts, and never took a snap Saturday. Instead, fifth-year senior Mark Murphy replaced Bell late, playing in a game for only the second time.

Mosley, who had 20 carries for 44 yards, ran for TDs to end the first two Baylor drives.

After the first touchdown, Mike Hamilton fumbled on Oklahoma State's next snap. The Bears needed 10 plays to go 38 yards, with Bell hitting Dominique Zeigler for 26 yards on third-and-20 and Rochon for 18 yards on third-and-8, before Mosley's second touchdown.

The Cowboys got within 38-21 when Julius Crosslin had a 1-yard TD run and Pena threw a 42-yard TD to D'Juan Woods in the third quarter.

Woods caught a 14-yard TD with 50 seconds left before the Cowboys recovered an onside kick that Parks couldn't handle. Pena threw a 3-yard TD to Brandon Pettigrew, but Oklahoma State couldn't recover another onside attempt.

Hamilton rushed for 73 yards, increasing his Cowboys freshman record to 941 yards.
