LOS ANGELES (AP) - Nnemkadi Ogwumike scored 32 points, her younger sister Chiney Ogwumike added 21 and No. 2 Stanford routed fourth-seeded Arizona 100-71 in the Pac-10 tournament semifinals on Friday.
Chiney had 13 rebounds and Nemkadi had 10 to help the top-seeded Cardinal (28-2) win its 22nd in a row overall and 56th consecutive league game. The Cardinal reached the 100-point mark for the third time this season.
Stanford advanced to Saturday's championship game at Staples Center against either second-seeded UCLA or No. 6 seed California, which met later. The Cardinal is seeking its fifth straight Pac-10 tourney title and eighth overall.
Kayla Pedersen added 16 points and Sarah Boothe 12 as the only other Cardinal players in double figures. The Ogwumike sisters helped Stanford dominate the boards, 41-29, and own a 64-18 edge in the paint.
Soana Lucet scored 17 points and Ify Ibekwe added 15 - making all nine of her free throws - for Arizona (21-11), which lost its 20th straight to the Cardinal. The Wildcats had their five-game winning streak end.
Stanford shot 53 percent in the first half, when the Cardinal led 45-24. Only two other players than the Ogwumike sisters scored, with Pedersen getting seven and Joslyn Tinkle two.
The Cardinal opened the game on a 13-3 run and later scored nine in a row as part of a 19-5 spurt that ended the half.
The only suspense occurred after Nnemkadi Ogwumike scored the game's first two baskets and her left contact lens came out. The game stopped while she went to the bench to put it back in.
Chiney briefly left the game in the second half after getting hit in the mouth. However, none of her teeth were dislodged and she returned to help Stanford extend its lead to 30 points.
The Wildcats cut their deficit to 68-45 with nine straight points, including seven in a row by Lucet. Boothe and Chiney Ogwumike scored four straight, followed by Nnemkadi Ogwumike with five straight that pushed Stanford's lead back to 30 points with 8:18 remaining.
The Cardinal ran through the league regular season schedule with an 18-0 record for the second straight year.
