Mouhamed Gueye's offensive rebound and putback off the glass with 43.6 seconds to play was the basket that sealed host Washington State's 56-51 win over in-state rival Washington on Saturday night in Pullman, Wash.

Gueye finished with 17 points and 15 rebounds for his 11th double-double of the season, and TJ Bamba led the Cougars (11-15 overall, 6-9 Pac-12) with 20 points, including a pair of free throws with seven seconds to play.

Noah Williams, who spent his first three seasons at Washington State before transferring to Washington, led the Huskies with 12 points. Washington (13-13, 5-10) got 11 points and 10 rebounds from center Braxton Meah.

Williams' jumper with 12:54 cut what had been a 10-point Washington State lead to 37-35. But Jabe Mullins connected on a pair of 3-pointers during a 10-2 run that gave the Cougars a 47-37 lead.

Then Washington State went ice cold, which allowed the Huskies to rally. The Cougars went more than five minutes without a point, and Washington cut the lead to 49-47 on a pair of free throws by Jamal Bey with 1:26 to play.

Bamba sank a pair of free throws after that, and the Cougars held on.

Washington started the first half without a point for more than 6 1/2 minutes, but Washington State led only 8-0 before the Huskies got on the board with Bey's 3-pointer.

Washington surged ahead 11-10 but would not lead again the rest of the night.

Mullins was falling down but managed to make a tip pass to Gueye, resulting in a transition layup and foul with 8:11 to go in the first half. Gueye made the free throw for a 15-11 Cougars lead.

Washington State went ahead 20-15 on a steal and dunk from Bamba, but Washington stormed back to tie. The Cougars then went on an 11-0 run, capped by back-to-back 3-pointers from Gueye and Justin Powell.

The Cougars took a 31-22 lead to halftime, with Washington having made just 8 of 27 shot attempts (29.6 percent).
