– Kansas' Devonte' Graham stole the show from Buddy Hield.

Graham scored a career-high 27 points and did a tenacious job defending the nation's No. 2 scorer to help the sixth-ranked Jayhawks defeat No. 3 Oklahoma 76-72 on Saturday.

"I just tried to make every shot tough on him," Graham, a sophomore guard, said of defending Hield. "He still knocked down five trey balls. He still got his shots off. He had a good game. I just tried to lock up and play the best defense I could."

It was only the third time in Graham's career that he scored at least 20 points. He made six of nine three-point attempts for the Jayhawks (21-4, 9-3 Big 12).

"All the stuff he did was big-time," Kansas forward Landen Lucas said. "He was a man today. He carried the team. We all just tried to do our part, and he finished it for us."

Kansas notched its fifth straight win and ended Oklahoma's 19-game home winning streak. The Jayhawks are tied for first place in the Big 12 with West Virginia.

Kansas won the first meeting 109-106 in triple overtime on Jan. 4, despite Hield's 46 points. This time, Hield scored 18 of his 24 points in the second half, but he went without a field goal in the first half and made five of 15 field goals overall.

"I had good shots in the first half, and I wasn't able to put them down," Hield said. "They guarded me really well and threw a lot of bodies at me."

Graham scored 17 points in the second half to help Kansas keep pace.

"He was great," Oklahoma coach Lon Kruger said. "He made big plays when they needed them, especially when we had a little bit of a lead, and we couldn't get a stop — he probably scored two or three of those. Good player. Talented guy. Stepped up there and made key buckets for them."

Isaiah Cousins added 21 points for the Sooners (20-4, 8-4). Oklahoma matched a season low by shooting 33.3 percent from the field. The Sooners, who entered the game leading the nation in three-point percentage, made only 10 of 32 shots from beyond the arc.

"That's about as good as we can play defensively," Kansas coach Bill Self said.

Kansas ran out to a 20-6 lead as the Sooners made just two of their first 19 shots. Hield didn't score until 9:04 remained in the first half.
