NORMAN, Okla. -- Sam Grooms scored a career-high 23 points, Steven Pledger had 17 of his 19 points in the first half as Oklahoma built a big lead and the Sooners held off Baylor's comeback attempt for a 90-76 victory on Saturday.

With the win, Oklahoma (18-8, 9-5 Big 12) remained ahead of the Bears in the conference standings and swept the season series after getting swept a season ago.

Grooms did most of his damage at the free-throw line, drawing frequent fouls as Baylor resorted to full-court pressure after falling behind. He went 15 for 17 on foul shots and Oklahoma went 39 for 45 to set season-highs in both categories.

Big 12 scoring leader Pierre Jackson scored 24 of his 28 points after changing shoes at halftime, but was unable to get Baylor (16-11, 7-7) any closer than 12 after trailing by 26 at the half.
