NEW YORK — Blake Griffin had 18 points, including the go-ahead free throws in overtime, and matched a career high with 21 rebounds to help No. 11 Oklahoma rally past No. 10 Purdue 87-82 on Friday in the championship of the NIT Season Tip-Off.

Willie Warren had a career-high 22 points and Taylor Griffin had 19 for the Sooners (6-0), who are off to their best start since winning their first 10 games in 2003.

E'Twaun Moore scored 22 points for Purdue (5-1), which jumped ahead 80-76 in overtime before Warren scored in the lane and Tony Crocker made a free throw. Blake Griffin got the ball inside with 1:05 left and was hacked across the arm, then made both free throws for an 81-80 lead.

Purdue never got a chance to tie it up. Moore was stripped before he could take a shot, and the Sooners sealed it from the free-throw line.
