LOS ANGELES -- Isaiah Thomas had 21 points and 11 assists, freshman Terrence Ross scored 17 points, and Washington overcame Klay Thompson's Pac-10 tournament-record 43 points for Washington State in a thrilling 89-87 victory Thursday night in the quarterfinals.
C.J. Wilcox hit five 3-pointers for the third-seeded Huskies (21-10), who barely hung on to a small lead through the final five minutes to avoid a season sweep by their sixth-seeded archrivals.
Thompson hit eight 3-pointers in his astonishing return from a one-game suspension but couldn't convert two chances to tie it in the final minute for the Cougars (19-12). Thompson missed a free throw with 48 seconds left and a 3-point attempt with 29 seconds to play.
Washington advanced to face seventh-seeded Oregon in Friday's semifinals.
