(AP) Layshia Clarendon scored 19 points to lead California a 73-63 victory over LSU on Saturday night, sending the Bears to the round of eight for the first time in program history.
Gennifer Brandon had 17 points and 13 rebounds, and Brittany Boyd added 14 points for second-seeded Cal (31-3), which will play Georgia in the Spokane Regional final on Monday night.
Theresa Plaisance had 15 points and 12 rebounds for sixth-seeded LSU (22-12).
The Lady Tigers were in the game until a scoring drought late in the second half ended their chances. They were seeking their first berth in the round of eight since 2008.
Fourth-seeded Georgia beat top-seeded Stanford 61-59 in Saturday's opening semifinal.
After the score was tied 26-26 at halftime, Cal opened the second half with an 8-2 run for a 34-28 lead.
But Adrienne Webb, Shanece McKinney and Bianca Lutley scored consecutive baskets for LSU to tie the score at 34-34.
The teams traded the lead several times after that.
Mikayla Miles hit a 3-pointer to cap a 9-2 run that gave Cal a 46-40 lead.
Brandon sank two free throws and a field goal to help the Bears take a 54-45 advantage, their biggest lead to that point, with 7:44 left. Boyd's 3-pointer pushed Cal's lead to 58-46 with 5:20 left.
LSU, meanwhile, went more than five minutes without a field goal and fell behind 62-46.
Webb broke LSU's field goal drought with 2:28 left in the game, but by then the Lady Tigers trailed 64-49.
Cal shot just 37.9 percent in the game, but made 50 percent of its shots in the second half. Cal had the edge in rebounding, 42-41.
The Lady Tigers shot 38.8 percent. They committed 16 turnovers to 11 for Cal.
Neither team shot well in a low-scoring first half.
California took a 9-4 lead before LSU went on an 8-2 to go up 18-16. The teams traded baskets after that and two free throws by Cal's Brandon tied the score 26-all at halftime.
LSU shot 40 percent in the first half, and was led by Plaisance's eight points. McKinney, a 6-foot-4 forward, had five blocks in the first half for the Lady Tigers.
Cal shot just 29 percent in the half, and Clarendon was held to just two points.
LSU and Cal were playing for the first time since their sole previous meeting in 1981.
Cal's 31 wins extended the team record set this season.
Cal tied Stanford for the Pac-12 regular-season title, and lost to UCLA in the conference tournament.
The Lady Tigers are down to eight players on their roster, including Jeanne Kenney, who was able to return to action Saturday after missing a game because of a concussion.
