LaBrittney Jones scored 18 points, including making 10 of 13 free throws, and blocked seven shots as Arizona held off USC 67-62 on Sunday.
Jones grabbed the rebound of a Courtney Jaco missed 3-pointer, preventing USC from forging a 65-65 tie, and was fouled with three seconds left. She made both free throws to push the game out of reach. Arizona (14-15, 5-13 Pac-12) emerged as the 11th seed in the conference tournament.
Jaco finished with 12 points for the Trojans (14-15, 5-13) but was 2 of 8 from 3-point range. Minyon Moore led USC with 21 points, three assists and three steals. USC was awarded the No. 9 seed and opens the Pac-12 tourney against eighth-seeded Cal March 2 at Seattle's Key Arena. Arizona meets sixth-seeded Oregon later that day.
Jones has scored 1,230 points in her career, moving up to 12th on the Wildcats all-time list. Malena Washington and Dejza James scored 14 each for Arizona.
