Chiney Ogwumike had 16 points and 11 rebounds and No. 1 Stanford beat Long Beach State 77-41 on Sunday in its first game holding the top spot in the poll in nearly eight years.
Joslyn Tinkle added 18 points and seven rebounds and Amber Orrange scored Stanford's first seven points of the game and finished with 13 for the Cardinal (6-0), who extended the nation's best home winning streak to 81 games at Maples Pavilion.
Orrange also had nine assists - two shy of her career best - and grabbed seven rebounds, regularly looking to find Ogwumike in the paint. Ogwumike powered to the basket on the block to draw quick fouls on the 49ers posts.
Alex Sanchez scored 14 points but was her team's lone player in double figures as cold-shooting Long Beach State (3-4) lost its sixth in a row to the Cardinal in the series. Sanchez, who came in averaging a team-leading 14.4 points per game, shot 5 for 12.
Ogwumike crashed the offensive glass for five offensive boards as the Cardinal held a 43-32 rebounding advantage. Taylor Greenfield came off the bench for 11 points with three 3-pointers.
Stanford made 6 of its first 8 3s, two each by Tinkle and Bonnie Samuelson - and both of Samuelson's 3s came during a 21-2 run that broke the game open midway through the first half and put the Cardinal ahead 36-11. They wound up 10 for 24 from long range.
The 49ers rallied from 22 points down in the second half of a 77-69 win against Utah Valley on Friday night, but were overmatched from the opening tip against the aggressive, up-tempo Cardinal.

Stanford's defense held Long Beach State to 18 total field goals in the first meeting between the schools in 19 years - since a 122-49 victory on Dec. 8, 1993, that set the Cardinal's single-game scoring record that still stands.
The Cardinal took over the top spot in The Associated Press poll Monday from Baylor after ending the Lady Bears' 42-game winning streak in the Rainbow Wahine Classic on Nov. 16 in Honolulu.
Stanford narrowly edged Connecticut for the No. 1 spot in this past week's poll, and the Huskies will visit Maples on Dec. 29.
If Stanford's unbeaten run at home remains intact, UConn will be determined to end that streak after the Cardinal snapped UConn's record 90-game winning streak with a 71-59 home victory in December 2010.
The Cardinal, ranked No. 1 for the first time since the final poll of the 2005 season, shot 54.3 percent in the first half while holding Long Beach State to 24.3 percent (8 for 33) on the way to a 49-20 lead.
The 49ers finished the day a dismal 18 for 66 (27.3 percent). They still lead the all-time series 8-7, including 7-6 in in the NCAA era.
