Oklahoma forward Taylor Griffin, right, takes a shot over Oklahoma State center Ibrahima Thomas. Griffin led the Sooners with a career-high 20 points in their 64-61 victory Monday in Norman, Okla.

Norman, Okla. ? Taylor Griffin got wrapped up in a headlock and got slammed to the ground. Then he and his brother made sure Oklahoma got the last laugh.

Griffin scored a career-high 20 points and brother Blake Griffin converted the go-ahead three-point play in the final minute to lead Oklahoma to a 64-61 defeat of Oklahoma State in a heated Bedlam rivalry game Monday night.

“That’s just Bedlam,” Taylor Griffin said. “Everybody was cool after the game. It’s a part of the game. You’ve got to love that.”

For the first time since the 1999 Big 12 Conference tournament, neither basketball team entered Bedlam ranked. But the rivalry didn’t need rankings to make it interesting.

The heat got cranked up just after halftime, when Oklahoma State’s Martavius Adams was called for an intentional foul for grabbing Taylor Griffin around the neck and throwing him to the floor.

Taylor Griffin came up with a loose ball on the Cowboys’ next possession, and went the length of the floor for a two-handed jam before linking his hands at the thumb and flapping his hands to mimic the gesture Oklahoma State’s Marcus Dove flashes after a dunk.

“I thought both teams just were playing so hard. I don’t think there was anything malicious about anything that happened,” Oklahoma coach Jeff Capel said. “I thought both teams were competing, both teams were battling.

“In the heat of competition, things happen when you have so many big guys. You had some hard collisions at times.”

Including the dunk, the Sooners scored the first nine points of the second half during a 13-2 run and took a 40-34 lead on Crocker’s three-pointer. The Sooners extended it to 53-45 after Blake Griffin’s two free throws with 4:43 remaining, but Oklahoma State rallied to tie it at 57-57 on Obi Muonelo’s 3-pointer from the left wing with 1:25 left.

That’s when the younger Griffin came through.

After David Godbold missed an off-balance three-point attempt with the shot clock expiring, Blake Griffin pulled off an acrobatic putback that put the Sooners ahead with 54.5 seconds left.
