Thompson, who scored one point in Stanford's win over UCLA on Friday, made hr first three shots of the game and scored 13 in the first half.

Stanford plays again Saturday, when Washington State visits Maples Pavilion for a 12:30 p.m. tip-off. The Cardinal needed overtime to beat the Cougars in Pullman three weeks ago.

Erica McCall (11) and Amber Orrange (10) combined for another 21 points as Stanford (7-1 in the Pac-12, 15-5 overall) kept pace with the conference leaders. The Cardinal finishes the week in a second-place tie with Arizona State, a game back of Oregon State and a game ahead of California.

Stanford sophomore guard Lili Thompson kept her eyes forward, refusing to allow one bad shooting night define her season. She was nothing short of spectacular on Sunday.

The Cardinal, which has won none of its last 10, held a double-digit lead most of the second half, with 17 its biggest advantage.

"We are a very good shooting team with a great shooting lineup out there," Stanford coach Tara VanDerveer said. "I like the fact that we took care of the ball tonight and shot a good percentage. We're a very good team, an explosive team, and we know that."

McCall, who also led the team with six rebounds, scored six straight points to put Stanford ahead to stay with 13:36 left to play in the first half. She sparked a 13-0 run.

"I think we came in with an attitude that we didn't want to get down like we have in past games and then try to battle back," Thompson said. "We wanted to commit to staying aggressive the entire game and I think we did that tonight."

Bonnie Samuelson hit a pair of 3-pointers and is five shy of matching Nicole Powell (201) for sixth on the Cardinal's all-time list.

Orrange had three assists in the game and needs three more to become the seventh player in Stanford history to reach 500.
