Oklahoma's Buddy Hield scored a career-high 23 points and four other Sooners finished in double figures to help Oklahoma beat North Texas 95-82 Monday.
After scoring a career-high 19 points in an 82-73 season-opening win against Alabama on Friday, the sophomore Hield again led the Sooners (2-0) in 29 minutes of work.
Tyler Neal added 12 points while Je'Lon Hornbeak, Ryan Spangler and Cameron Clark each had 11 for the Big 12 Conference Sooners.
Alzee Williams led the Mean Green (1-1) with 24 points.
After trailing the first 2:27, Oklahoma used an 8-0 run to take a 12-8 lead. Hield keyed a 9-0 run later in the half with a driving basket and then a three-pointer in transition to give the Sooners a 14-point lead - their largest of the game.
The Sooners shot 53 percent from the floor, never trailing after the 15:41 mark to win their 21st consecutive home opener.
Oklahoma led 48-38 at the half after shooting 53 percent and converting six of 12 three-point shots.
Conference USA's North Texas out-rebounded the Sooners 23-19 in the first half but turned the ball over seven times, leading to 13 Oklahoma points.
The Mean Green committed 16 turnovers and 22 fouls.
Chris Jones scored 16 points and Keith Coleman added 14 for North Texas. Jordan Williams scored 13 in 28 minutes.
North Texas closed to within four points with 12:14 remaining on a Williams' 3-pointer but Hornbeak answered on the other end the next trip down and Hield converted a pair of free throws a minute later.
North Texas was without junior guard T.J. Taylor for a second straight game due to illness and a sore knee. Coach Tony Benford - who calls Taylor one of his three best players - said the junior is expected to make his Mean Green debut Thursday night when North Texas hosts Nicholls State.
