Pepperdine's Lorne Jackson scored on a layup with 12 seconds left in overtime, and out of a timeout the Washington State Cougars turned the ball over to give the Waves an ugly 58-56 win in Malibu, Calif., their first victory of the year.
Jackson led the Waves with 15 points, outscoring WSU's bench that only produced seven points total.
Washington State (2-1) built a 28-19 lead with three minutes to play in the first half, but the Waves chipped away and only trailed 30-26 going into halftime.
The Cougars rebuilt an advantage in the second half and led 50-42 with less than four minutes to play. But Jackson came to the rescue again, hitting two three pointers as Pepperdine used an 8-0 spurt to tie it by the end of regulation.
The Cougars fell to 2-1 on the season on Friday as Brock Motum struggled. The Australian center scored 15 but only connected on 4-of-13 shots from the floor. He had five turnovers as well, part of 19 total for coach Ken Bone's squad.
WSU guard Mike Ladd recorded a double-double with 10 points and 13 rebounds, and Royce Woolridge was the only other WSU player in double figures with 11.
Waves forward Stacy Davis scored 14 points, and guard Jordan Baker went 4-of-7 from three-point range to scored 13. Baker also had five steals.
Neither WSU nor Pepperdine shot above 42 percent from the floor.
