Brett Hundley tossed a trio of touchdown passes on Saturday, as No. 17 UCLA downed Washington State, 44-36, in a Pac-12 tilt at Martin Stadium.
Hundley completed 18-of-21 passes for 261 yards with an interception. Johnathan Franklin rushed for 66 yards on 19 carries and added 45 yards and a score on four catches for the Bruins (8-2, 5-2 Pac-12), who control their own destiny in the South Division of the Pac-12 heading into a showdown with USC next Saturday.
The Trojans, who disposed of Arizona State earlier on Saturday, trail the Bruins by one-half game in the conference.
Connor Halliday finished 26-of-43 for 330 yards, five touchdowns and one interception for the Cougars (2-7, 0-6), who were playing without star receiver Marquess Wilson. He left the team following his suspension earlier in the week.

The Bruins then made it a 37-7 contest late in the first half, as Halliday was sacked by Cassius Marsh, who knocked the ball loose. Eric Kendricks picked up the fumble and carried it 40 yards to the end zone for a 30-point UCLA lead heading into the break.
