Tahj Eaddy scored a season-high 21 points, Drew Peterson finished with 15 points and 11 rebounds, and USC led Washington State wire-to-wire en route to an 85-77 Pac-12 Conference win on Saturday in Los Angeles.

The Trojans (11-2, 5-1 Pac-12) scored the game's first five points, pushed their lead to 10 points a little more than midway through the first half, and held the Cougars at bay for the duration.

Evan Mobley finished with 16 points and dished four assists, but was limited in the second half due to foul trouble. He was whistled for his fourth personal with 12:03 remaining and did not return until 6:35 left.

The absence of Mobley, the team's season-long leading scorer and rebounder, gave Washington State (9-4, 2-4) a chance to hang around.

Buoyed by Isaac Bonton's 27 points, the Cougars trimmed a deficit that reached 15 points down to four with 4:30 remaining.

Noah Williams capped an 11-0 Cougars run with a three-point play for three of his 14 points. Efe Abogidi tallied 10 points and 12 rebounds for Washington State, and blocked two shots.

Dishon Jackson, who finished with 14 points and seven rebounds, also blocked a pair of shots. Jackson and Abogidi both matched up with USC's Isaiah Mobley, holding the forward to seven points just one game removed from his career-high 18 in Thursday's win over Washington.

Though his scoring production was limited, Isaiah Mobley contributed offensively with four assists. On the last, he fed Eaddy on the wing for a critical jump shot with less than three minutes remaining and USC clinging to a four-point lead.

Eaddy's jumper off of Isaiah Mobley's pass sparked a decisive 6-0 Trojans run.

Isaiah White added 13 points for USC. Chevez Goodwin grabbed three of his five rebounds on the offensive end, while the Trojans pulled down 14 offensive rebounds as a team. USC outscored Washington State in points-off-turnovers, 24-to-7.

The win is the Trojans' sixth straight on the season, and ninth head-to-head against Washington State.
