NORMAN, Okla. (AP) — Oklahoma guard Isaiah Cousins ruined Baylor's Plan B.
The Bears, burned by 11 Sooners 3-pointers in the first half, extended their defense in the second half to stop the onslaught. Cousins responded by attacking the basket and scoring 15 of his career-high 21 points after the break to help No. 21 Oklahoma beat Baylor 88-72 on Saturday night.
Cousins, Oklahoma's fifth-leading scorer for the season at just over 10 points per game, said the opportunity was right for him to carry more of the scoring load. He shot 4 of 7 from the field and 6 of 6 on free throws in the second half.
"My teammates wanted me to be more aggressive," he said. "I just had to step up and do what I do — attack and try some scoring. It turned out to be a pretty good day."
Oklahoma coach Lon Kruger said Cousins' performance was a byproduct of unselfish team play.
"The guys have done a good job of moving the ball," Kruger said. "We've been focusing lately on getting a good shot out of every possession. They don't care who gets it."
Cousins, a sophomore, also had seven rebounds and shot 3 of 4 on 3-pointers.
"Isaiah, I thought, was terrific all night long," Kruger said. "He was making a lot of good plays and working hard defensively and rebounding the ball as well."
Buddy Hield scored 19 points and Cameron Clark added 16 for the Sooners (18-6, 7-4 Big 12), who made a season-high 14 3-pointers and snapped a two-game skid. The Sooners shot a season-high 53.6 percent overall to bounce back from losses to Iowa State and West Virginia.
Isaiah Austin scored a season-high 21 points for Baylor (14-9, 2-8), which once again was competitive in a losing effort. The Bears, who spent the first three months of the season ranked in the Top 25 and cracked the Top 10, lost for the seventh time in eight games.
Baylor shot 46 percent in the first half but just 39 percent in the second.
The teams combined to make 23 3-pointers. Oklahoma took 29 shots from 3-point range and 27 inside the arc, while Baylor took 23 of its 59 shots from 3-point territory.
