Tahj Eaddy scored 24 points and No. 19 Southern California led by 16 after a blistering start on its way to a 72-58 victory over Oregon on Monday night in Los Angeles.

The Trojans (19-4, 13-3) moved into sole possession of first place in the Pac-12 by dominating the Ducks with just a seven-man rotation. Second-leading rebounder Isaiah Mobley strained his right calf earlier in the day and missed his first start of the season.

LJ Figueroa and Eric Williams Jr. scored 14 points each for Oregon, which had its five-game winning streak snapped. The Ducks (14-5, 9-4) came in tied with USC and UCLA at three losses apiece in league play.

Eaddy scored USC's first nine points — all on 3-pointers — and the Trojans raced to a 17-1 lead while the Ducks missed their first 12 shots. Eaddy, a graduate transfer from Santa Clara, hit five 3s in the half, his last one giving USC a 23-point cushion, its largest of the period.

The Trojans made 17 of 26 shots in the half. Oregon missed seven of eight 3-pointers and shot 10 of 29 from the floor.

The Ducks tried a full-court press in the second half, but it didn't stop the explosive Trojans. They got 15 points and a season high-tying 11 rebounds from Drew Peterson, and 11 points from Evan Mobley. USC outrebounded the Ducks 39-26.

Eaddy's sixth 3-pointer early in the second half extended USC's lead to 26.

After trailing by 18, the Ducks got to 64-54 on consecutive 3s by Figueroa, who had two, and Williams, who finished with four fouls and nine rebounds.

Max Agbonkpolo hit a 3-pointer from the right corner for the Trojans, sparking a 5-0 run capped by Mobley's third dunk of the game that kept them ahead 72-56.

The Ducks outscored USC 36-29 in the second half, but were held without a field goal over the final 5 minutes.

Oklahoma State 74, (18) Texas Tech 69: Cade Cunningham scored 20 points and Oklahoma State got past Texas Tech in overtime for the second time this season, beating the 18th-ranked Red Raiders in Stillwater, Oklahoma.

Cunningham, the Big 12's leading scorer and one of the nation's top freshmen, put on a show in front of about a dozen NBA scouts and executives, including Oklahoma City Thunder general manager Sam Presti. He made 8 of 13 shots and had five rebounds.

Kalib Boone scored 18 points and Avery Anderson III added 16 for the Cowboys (15-6, 8-6 Big 12), who rallied from an 11-point second-half deficit with Cunningham on the bench due to foul trouble. Oklahoma State also beat Texas Tech in overtime on Jan. 2 and is 3-0 in OT games this season.

Oklahoma State made 15 of 24 free throws in regulation but drained 7 of 8 in the extra period to claim its third straight win.

Terrence Shannon Jr. scored 18 points and Mac McClung added 17 for Texas Tech (14-8, 6-7), which lost its third consecutive game.

Tech led 37-36 at halftime. The Red Raiders scored the first six points of the second half, and Oklahoma State coach Mike Boynton called a timeout.

Cunningham committed his fourth foul three minutes into the second half. Shortly after Cunningham sat, McClung hit a tough turnaround jumper to put Tech up 45-36. The Cowboys missed their first nine shots of the second half and didn't score for more than 6 1/2 minutes.

Oklahoma State rallied without Cunningham. Keylan Boone made a 3-pointer to finally get the Cowboys on the board in the second half. Anderson's layup on a baseline cut tied the game at 47, and Oklahoma State finally took the lead on a pair of free throws by Kalib Boone.

Oklahoma State could have won in the closing seconds of regulation, but Rondel Walker missed a 3-pointer at the buzzer.
