LUBBOCK, Texas (AP) Texas Tech had opportunities to extend their halftime lead against No. 12 Oklahoma State in the third quarter but the Red Raiders couldn't put together scoring drives.
''We didn't do what we needed to do in the fourth quarter, but I thought in the third quarter, I thought they played hard'' despite not scoring, Texas Tech coach Kliff Kingsbury said after his team's 70-53 loss to the Cowboys on Saturday. ''Kept giving us the ball back with opportunities to go up 17 multiple times and we didn't get it done offensively.''
Mason Rudolph and J.W. Walsh each threw for two touchdowns while Raymond Taylor scored two rushing TDs as No. 12 Oklahoma State came from behind to remain undefeated and still in the hunt for the Big 12 title.

The combined points were the third most involving a ranked team without playing overtime.
The 70 points were the most ever given up by the Red Raiders in Lubbock.
Walsh found James Washington twice in the fourth quarter, once for 75 yards and then for 73 yards to seal the win for the Cowboys (8-0, 5-0).
Raymond scored from 4 and 28 yards. His second TD put the Cowboys ahead for the first time.
Ramon Richards returned an interception 59 yards for a score with six seconds left in the game.
Texas Tech's Jakeem Grant returned a kickoff 100 yards - the fourth of his career and a Texas Tech record - and had a 90-yard catch.
Grant said he felt like the Red Raiders lacked focus in the second half.
''Just felt like we weren't executing as much as we were in the first half,'' the senior said. ''We were making big plays. In the second half we just came out and they just basically we weren't focused enough to finish the game out.''
Patrick Mahomes completed 38 of 55 passes for 480 yards and four touchdowns for the Red Raiders (5-4, 2-4). He also threw two interceptions. Both led to touchdowns.
Rudolph completed 21 of 35 passes for 285 yards, and Walsh completed 4 of 5 for 167 yards.
Oklahoma State finished with 662 total yards to 642 for the Red Raiders.
''When you play them, it's going to be a long game and you're going to have a lot of plays and (Kingsbury) does a great job with them on offense,'' Cowboys coach Mike Gundy said. ''He's very intelligent in how he spreads people out and gets the ball in space. But when you do that, the clock stops a lot.''
The Cowboys held Texas Tech scoreless in the third quarter.
Reviews gave Oklahoma State two touchdowns -a 12-yard pass from Rudolph to Hays in the far corner of the end zone that showed his foot came down in bounds and a 3-yard TD pass to Brandon Sheperd that showed he had possession.
There were plenty of big plays to go around. Oklahoma State's first big-yardage play of the game came midway through the third quarter when Jalen McCleskey returned a punt 67 yards to pull the Cowboys within 38-35. Walsh then rushed 64 yards to the Texas Tech 1. He scored on the next play.
After falling behind early the last three contests in Lubbock, the Red Raiders jumped ahead early, going up 17-0 on two touchdown passes from Mahomes to sophomore Justin Stockman and a 42-yard field goal that came after Dakota Allen intercepted Rudolph at the OSU 41.
Grant's 90-yard catch was the longest reception by a Red Raiders player since a 95-yarder by Rodney Blackshear against Houston in 1991.
Grant got his second TD early in the second quarter when Mahomes found him over the middle for a 12-yard score.
