NORMAN, Okla. — Amanda Thompson scored a career-high 29 points and teamed with Jasmine Hartman as the unlikely leaders of No. 11 Oklahoma’s record-setting 3-point avalanche in a 95-62 rout of No. 20 Oklahoma State on Sunday.

Thompson and Hartman each made four 3-pointers for the first time in their careers as Oklahoma (21-9, 11-5 Big 12) broke the school record with 16 3-pointers on 27 attempts.
Thompson had three of Oklahoma’s eight 3-pointers during a 29-8 surge that broke open the game after a closely contested first 7 minutes. A career 27 percent outsider shooter who had missed 12 of her 14 attempts over the past six games, Thompson was 4 for 4 in her final regular-season game at the Lloyd Noble Center.
Andrea Riley, the nation’s third-leading scorer, led Oklahoma State (21-9, 9-7) with 25 points.
Oklahoma claimed the third seed and a first-round bye at next week’s Big 12 tournament.
Coming off a 23-point loss at Texas A&M that was their most lopsided in over a year, the Sooners put on a show in front of former national player of the year Courtney Paris.
Oklahoma made 15 of its first 20 shots, including eight of 11 from 3-point range, claiming a 42-20 lead after Danielle Robinson went coast-to-coast for a layup and turned it into a three-point play.
Carlee Roethlisberger got into the 3-point spirit to put Oklahoma up 24 before the Cowgirls scored the final five points of the first half.
Thompson and Hartman each had 3s as the Sooners stayed hot in the second half, and Hartman added bookend 3-pointers in a 12-2 run that pushed Oklahoma’s lead to 71-36 with 14:30 remaining. Hartman, who had made only four 3-pointers all season, went 4-for-6 and finished with a career-high 14 points.
Nyeshia Stevenson added three 3-pointers and 15 points, Robinson had 13 points and nine assists and senior Abi Olajuwon had 10 rebounds. The Sooners’ previous record for 3-pointers had been 14 in games against Iowa State in 1996 and Colorado in 2001.
The Sooners danced in a circle at halfcourt after claiming a trophy for sweeping the Bedlam rivalry this season.
Riley surpassed Liz Brown’s school season assists record and Precious Robinson added 12 points off the bench for Oklahoma State, which got only five points on 2-for-12 shooting from second-leading scorer Tegan Cunningham.
Cunningham, who had been averaging 16.8 points, was also called for an intentional foul after she clocked Roethlisberger in front of the Sooners’ bench with 8:40 left in the first half — right in the middle of Oklahoma’s big run. Officials, who had originally called only a personal foul, reviewed the play on a courtside monitor and upgraded the foul.
