TUCSON, Ariz. (AP) - Shaquala Williams scored 18 of her 24 points in the second half as Oregon erased a 22-point deficit to upset No. 20 Arizona 75-71 Saturday.
The Ducks (22-7, 13-4 Pac-10) trailed 55-33 in the opening moments of the second half.
Oregon rallied back with Williams' 3-pointer putting her team ahead to stay at 68-67 with 4:09 remaining.
The Ducks held on from there as Brianne Meharry, Jamie Craighead and Williams all made free throws in the final 2:02.
Arizona (22-6, 11-5) had a couple of attempts to tie the game in the final 10 seconds. But an errant 3-point try by Reshea Bristol and then a turnover with 1.9 seconds ruined any comeback hopes.
Courtney Moore finished with 17 points off the bench for Oregon and Craighead added 11.
Tatum Brown and Lisa Griffith scored 12 points apiece while Angela Lackey and Bristol each had 11 for Arizona, which blew a 36-29 halftime lead.
