Chiney Ogwumike scored 13 of her 19 points in the second half, and No. 4 Stanford overcame its worst scoring first half of the season to knock off pesky Colorado 69-54 in the quarterfinals of the Pac-12 Conference tournament Friday.

Ogwumike, the conference player of the year, gave Stanford the lead for good with a rare 3-pointer early in the second half that was part of a 16-2 run by the Cardinal to take control.

Stanford, the top seed in the tournament, was held to a season-low 21 points in the first half. The Cardinal (29-2) will face either No. 5 seed USC or fourth-seeded Arizona State in the semifinals Saturday night. Stanford has won seven straight conference tourney titles.

Colorado (17-14) was led by 16 points from Brittany Wilson.
