STANFORD, Calif. — Stanford's Nnemkadi Ogwumike felt a tingling sensation in her right elbow after colliding with another player early in the first half against Washington State.

The Pac-10's leading scorer went to the bench twice to get treatment, came back wearing a protective rubber sleeve on her elbow then proceeded to shred whatever defense the Cougars tried to throw at her.

Ogwumike had 22 points and 13 rebounds, Kayla Pedersen added 13 points and 10 rebounds and the second-ranked Cardinal rolled to an 80-43 victory last night.

"I just hit arms with somebody," Ogwumike said. "At first it was just kind of tingly but then (team trainer Tomoo Yamada) got a little bit of a pad on it and it helped me out."

Keeping Ogwumike healthy and on the court was key for Stanford (14-1, 4-0 Pac-10), which lost guard Jeanette Pohlen to a right ankle injury in the second half.

With J.J. Hones out with a sore left knee, the injury to Pohlen thinned Stanford's ranks though it didn't slow down the Cardinal against the smaller, slower Cougars (5-11, 0-5).
