Oregon State had an opportunity to make a game of it with No. 4 Stanford - maybe even pull off a big upset.But the Beavers just couldn't get the late defensive stops Sunday night.Chiney Ogwumike posted her sixth straight double-double with a career-high 32 points and 18 rebounds to lead the No. 4 Cardinal to a 65-45 win over the Beavers."Those stops that they got allowed them to relax and stretch it again. I thought that was really the game," Oregon State coach Scott Rueck said.Stanford coach Tara VanDerveer credits Ogwumike for her consistency. She's scored in double digits in all 21 of Stanford's games and has reached double digits in rebounds 17 times."The best thing I can be is level-headed, keep a smile on my face throughout the game and try to compete," said Ogwumike.Amber Orrange and Bonnie Samuelson - who hit four 3-pointers - added 12 points apiece for the Cardinal (20-2, 9-1 Pac-12).Jamie Weisner had 13 points and Ali Gibson added 12 for the Beavers (9-13, 3-7), who trailed by as many as 16 in the first half but closed to 35-26 when Ali Gibson opened the second half with a reverse layup.But Ogwumike, who fell one shy of her career high in rebounds, then scored six straight points to help Stanford regain control."She does everything for them. That's why they're who they are," Oregon State coach Scott Rueck said. "If you have one or two of those in the middle, you're going to win a lot of games."Samuelson made consecutive 3-pointers to stretch Stanford's lead to 49-28 before Oregon State chipped away, closing the gap to 54-42 on Gibson's 3-pointer with 6:53 left.That was as close as the Beavers would get as Stanford answered with five straight points.Stanford shot 38.5 percent (25 of 65) overall, while Oregon State shot 35.8 percent (19 of 53) in a matchup of the Pac-12's top two field goal percentage defenses."I just thought our defense was working really hard," VanDerveer said. "Some people weren't knocking down their shots like they usually do, but sometimes that happens."Stanford overcame a poor offensive game from Joslyn Tinkle. The senior forward came in averaging 12.9 points but scored just two on 1-of-8 shooting.Ogwumike and Orrange scored four points apiece in an early 13-3 Stanford run that put the Cardinal ahead 20-7. Stanford later scored eight straight, with Samuelson's second 3-pointer of the half giving the Cardinal a 28-12 lead.Weisner's layup capped a 6-0 Oregon State run that closed the deficit to 32-22.Ogwumike had 17 points and nine rebounds at the break to help Stanford to a 35-24 halftime lead.
