Blake Griffin had 26 points and 12 rebounds for his 20th double-double, Tony Crocker added 24 points with a career-high seven 3-pointers and No. 2 Oklahoma had to scramble late to hold off Colorado 77-72 on Saturday.
The Sooners (23-1, 9-0 Big 12) trailed only once but didn't shake free of the last-place Buffaloes until Griffin followed Crocker's fifth 3-pointer of the game by driving the lane for a right-handed dunk over two defenders. Griffin's jam gave Oklahoma its first double-digit lead at 56-45 with less than 11 minutes to play.
Colorado rallied back within 73-70 on Cory Higgins' jumper with 12.2 seconds left.
Higgins finished with 20 points to lead the Buffaloes (9-13, 1-7), who lost for the 23rd consecutive time in Norman and the 25th straight time in a Big 12 road game.
