NORMAN, Okla. (AP) -- TaShawn Thomas scored 24 points to help No. 18 Oklahoma beat No. 22 Baylor 73-63 on Saturday.
Thomas, a senior who transferred from the University of Houston before the season, made 11 of 17 shots and grabbed eight rebounds.
Buddy Hield had 20 points and 10 rebounds and Isaiah Cousins added 19 points for the Sooners (10-3, 1-0 Big 12), who won their third straight in the conference opener for both teams.
Freshman Johnathan Motley scored a season-high 24 points and Taurean Prince added 17 for Baylor (11-2, 0-1), which had won six straight. The Bears shot 46 percent in the first half, but just 29 percent after the break.
Baylor, which had held opponents to 55 points per game, allowed its highest point total of the season. Oklahoma made 21 of 25 free throws, while Baylor made just 12 of 18.
Baylor led 23-16 in the first half, but Hield hit back-to-back 3-pointers, pushing the ball after defensive rebounds and shooting before Baylor could set its defense to give the Sooners a 24-23 lead. Oklahoma led 37-33 at halftime behind 12 points from Thomas and 11 from Cousins. Prince and Motley each scored 12 points in the first half for Baylor.
Baylor made just one of its first seven shots after the break, and Oklahoma took a 46-37 lead on a 3-pointer by Cousins. The Sooners extended their lead to nine on a 3-pointer by Hield, and he drained another three with just over 6 minutes to play to push Oklahoma's lead to 58-46.
