– Buddy Hield made seven of his eight three-pointers in the second half on his way to a 32-point performance, Isaiah Cousins hit a go-ahead jumper with four seconds left and No. 1 Oklahoma overcame a 14-point deficit to escape with a 77-75 victory over LSU on Saturday.

"He got a couple of open looks in the second half that got him going," LSU guard Tim Quarterman said of Hield. "We were attached to him in the first half. He had a hard time at the beginning, but he got freed up during the fast break opportunities and they took advantage."

Cousins finished with 18 points, and Ryan Spangler had 16 points and 10 rebounds for the Sooners (18-2, 6-2 Big 12), who summoned the composure to rally down the stretch amid a rabid, packed crowd energized by the Tigers' strong play for much of the game.

LSU didn't go quietly. Antonio Blakeney hit a pair of late threes, and the second tied it at 75 with 24 seconds left.

Ben Simmons had 14 points for LSU (13-8, 6-2 SEC), highlighted by a crowd-pleasing reverse dunk. But those same fans were left frustrated, some hurling garbage, when Khadeem Lattin blocked Quarterman's driving shot as time ran out.

Many fans seemed to think Quarterman was fouled. There was contact, but it could have been tough to tell in real time who initiated it as the Sooners collapsed defensively into the paint.

Quarterman finished with a team-high 18 points, while Craig Victor scored 15. Blakeney finished with 11.

Simmons' driving reverse, two-handed dunk, which whipped the crowd into an arena-shaking frenzy, put LSU ahead 50-38. Soon after, the Tigers took their largest lead, at 14, when Keith Hornsby's jumper made it 52-38.

Oklahoma's comeback started with a jumper by Cousins with 13:41 left, which made it 57-46. That began a 22-8 run that included four threes by Hield, the fourth calmly drained from the left corner to put Oklahoma up 66-65 with 4:05 remaining.

Hield added yet another clutch three from the right wing just moments after snagging an offensive rebound of Cousins' miss. Cousins got the ball back on that possession and kicked it out to Hield for a shot that put Oklahoma up 73-72 with 1:53 left.

The Tigers led nearly the entire first half, when they shot 55.6 percent (15 of 27), including 7-for-12 from three-point range. LSU was up by as many as 13 points when Blakeney and Quarterman hit back-to-back threes, making it 36-23.

Jordan Woodard responded with a quick three to trim OU's deficit back to 10. Hield, who had 11 points in the first half, added two free throws minutes later to pull the Sooners to 41-36 before Aaron Epps' three widened LSU's lead back to 44-36 at halftime.
