(AP) -- Marcus Denmon scored 25 points, Ricardo Ratliffe added 15 points and 10 rebounds and No. 4 Missouri claimed first place in the Big 12 by edging Oklahoma 71-68 on Monday night.

Oklahoma (13-10, 3-8) had the ball with a chance to tie with 5 seconds left. Romero Osby was fouled with 2.5 seconds left and missed both free throws, and Steven Pledger missed a 3-pointer at the buzzer when the offensive rebound was tapped back to him.

The Tigers (22-2, 9-2) moved a half-game ahead of No. 6 Baylor and No. 7 Kansas in the standings.

Those teams meet Wednesday night for a chance to pull even with Missouri.

Pledger led Oklahoma with 22 points and Sam Grooms had a career-high 17 points and 10 assists.
