CORVALLIS, Ore. -- That wasn't the same Stanford team Oregon State faced earlier this season.
The Beavers were able to make a game of it Jan. 7 in a 67-60 loss in Palo Alto, Calif. But the third-ranked Cardinal turned up the defense Thursday night, rolling to a 78-45 road win.
"Their defense was definitely better than when we played them there," Oregon State guard Alyssa Martin said. "It did throw us off in the beginning, and we weren't able to bounce back and get acquainted to the game."
Nnemkadi Ogwumike had 27 points and nine rebounds for Stanford (23-1, 14-0 Pac-12).
"I try to do whatever my team needs me to do," the All-American forward said.
Chiney Ogwumike, Nnemkadi's sister, added 10 points, and Joslyn Tinkle had seven points and a career-high 14 rebounds for the Cardinal, who led by 20 at halftime and 38 in the second half.
Martin had 11 points for Oregon State (17-8, 8-6), which had won six straight.
Nnemkadi Ogwumike was outscoring Oregon State by herself, 27-26, after her basket with 12:49 remaining. That capped a run of nine straight Stanford points she scored. She left with 10:21 remaining and didn't return.
"She's huge. She's not just a great player, she's a great person. She works really hard," Stanford coach Tara VanDerveer said.
The Cardinal have won 20 straight games this season, 25 in a row against Oregon State and 71 consecutive games versus Pac-12 teams.
Stanford shot 29-of-61 (47.5 percent) from the floor, while Oregon State was 19-of-57 (33.3).
"Their defense was really good tonight. They did a great job defending us," Oregon State coach Scott Rueck said. "They played us perfect to start with. Nothing was easy. Then we didn't hit a few of the shots I thought we needed to hit to get into the game and relax."
The Cardinal went 10-of-22 from the 3-point line, including three makes apiece by Toni Kokenis and Bonnie Samuelson. Oregon State was 2-of-16 on 3-pointers.
Both teams struggled early on offense. Stanford led 8-2 after Chiney Ogwumike's basket a little more than seven minutes into the game.
But the Cardinal soon pulled away. Lindy La Roque scored the last five points of a 15-2 run that put Stanford ahead 23-7.
Nnemkadi Ogwumike, who shot 10-of-16 overall, later scored six straight points for a 31-9 Cardinal lead.
Stanford was up by as many as 22 in the first half and 36-16 at halftime, led by Nnemkadi Ogwumike's 16 points.
In the first meeting between the teams this season, Oregon State led 35-31 at halftime after holding Stanford to 12-of-33 shooting. The Beavers still had a lead with less than 11 minutes left before the Cardinal went on to lead by double digits.
Stanford faced primarily a zone defense against Oregon State in that first game and prepared for it again.
"This week we really worked on getting our cuts down, flashing and hitting the posts. They were stepping up big, inside and out," Kokenis said. "They helped us move the ball in the zone and get a lot of easier shots than the first time we played."
VanDerveer, who has 697 career wins, said several factors contributed to the close contest the first time the teams played.
It was Stanford's second game in three nights, with just a day to prepare, and the Cardinal had not seen some of Oregon State's first-year players.
"They definitely had our team's attention. I also think we worked hard against the zone this week and were ready for it," VanDerveer said. "Our team knocked down perimeter shots. Our team shot the ball well. I thought our team worked extremely hard defensively."
