NORMAN, Okla. (AP) Oklahoma's defense matched its high-octane offense, and the result was a blowout victory over Texas Tech.
Buddy Hield scored 30 points to help the top-ranked Sooners defeat Texas Tech 91-67 on Tuesday night.
Hield, the nation's No. 2 scorer, made 9 of 12 shots, including 5 of 8 3-point attempts, and 7 of 8 free throws. It was his seventh game with 30 or more points this season. Isaiah Cousins scored 19 points and Jordan Woodard added 15 for the Sooners (17-2, 6-2 Big 12), who shot 53 percent to remain in first place in the conference.
The Sooners matched a school record with 14 blocked shots and held Texas Tech (12-7, 2-6) to 32 percent shooting. Khadeem Lattin had a career-high eight blocks and altered several more shots.
''Very impressed with Oklahoma,'' Texas Tech coach Tubby Smith said. ''They are deserving of number one. They're playing with a lot of confidence. We ran into a team that really shot the lights out tonight.''
Lattin, a 6-foot-9 sophomore, averages 4.25 blocks in Big 12 play. He had the Red Raiders thinking twice when they attacked the rim.
''We beat certain defenders off the dribble, and sometimes, it looks like a shot's open, and you're ready to go in for it - maybe a layup or a jump shot, and he comes out of nowhere and swats it away,'' said Justin Gray, who led the Red Raiders with 20 points. ''You kind of have that in the back of your mind.''
Devaugntah Williams had 12 points and Matthew Temple added 11 for Texas Tech.
Oklahoma led 17-13 before Hield hit two 3-pointers during an 8-0 run to push the lead to 25-13.
The Sooners led 49-39 at halftime. Hield had 16 points, Woodard scored 13 and Lattin had six blocks at the break. The Sooners made 8 of 12 3-point attempts and shot 58 percent from the field in the first half.
Gray scored 12 points in the first half to help the Red Raiders stay in it.
The Sooners started to pull away early in the second half. They led 51-42 when Hield hit a jumper, sparking a 13-5 run that put the Sooners up 64-47 and in control for good.
The Sooners, who entered the night leading the nation in 3-point percentage at 46 percent, increased their percentage by making 12 of 23 from beyond the arc. Oklahoma shot at least 50 percent from 3-point range for the third straight game.
''So many people can score, you can't help off Buddy, or any of them at all,'' Smith said.
Former Ohio State guard Austin Grandstaff has transferred to Oklahoma. He appeared in 10 games for the Buckeyes, averaging 4.4 points in 11.5 minutes. He will be required to sit out two semesters and will be eligible to play for the Sooners at the conclusion of the fall semester of the 2016-17 season. He will be classified as a sophomore.
QUOTE OF THE NIGHT
Hield, on comparisons between the Sooners and the Golden State Warriors' styles: ''We can like it, but we perfect Oklahoma Basketball. Those guys are on another level than us, but we share the ball very well and Warriors share the ball well too. I watch them a lot, but we just do what coach wants us to do. Sharing the ball helps our team go, and a lot of guys are making shots.''
