E.J. Singler scored 22 points and Oregon dominated Vanderbilt in a 74-48 victory Friday night.
Freshman guard Damyean Dotson had his third double-digit scoring game for the Ducks (3-0) with 10 points, and Tony Woods had 10 as well.
Kyle Fuller scored 17 points to pace the Commodores (1-1), who lost coach Kevin Stallings to an ejection with 15:57 to play after he was whistled for a pair of technical fouls for arguing with officials. Kedren Johnson added 14 points for Vanderbilt.
Oregon led 41-20 at halftime, and the Commodores never got closer than 14 points in the second half.
"We knew how big of a game this was for us as a collective unit, a test to kind of measure where we're at," said Singler. "We came out and really showed a good team effort."
The Ducks held a 17-14 lead midway through the first half before exploding for 24 points in the final 9:25, starting with an 11-0 run that included two 3-pointers by Dotson and a 3-pointer and jumper from Singler to make it 28-14 with 7:38 before halftime.
Fuller ended Vanderbilt's scoreless stretch with a layup with 6:41 to play in the half, but the Commodores didn't make another field goal the rest of the half, missing on their next six attempts.
The Ducks, meanwhile, were just heating up. They finished the first half on a 13-2 run, capped by a long 3-pointer from Johnathan Loyd as time expired.
"I thought we got a lot of fast-break points through that stretch, and I thought they got a little tired of us running up and down," said Singler, who also had six assists and five rebounds. "I thought we got some good easy looks and we kind of just broke it open from there."
"We just played poorly," said Stallings, who wouldn't comment on his ejection. "They knocked us back on our heels and we didn't respond very well."
Oregon shot 50 percent from the field in the first half and scored 16 points off 11 turnovers by the Commodores, who shot just 27 percent.
Overall, the Ducks outshot the Commodores 46 percent to 34 percent. Vanderbilt, which made 12 3-pointers in its season opener against Nicholls State, was just 4 of 21 from long range against Oregon.
"We knew they were going to shoot 3s coming in," Singler said. "That was a big emphasis on us this week, containing the 3 and not letting them get good open looks."
In his first game as a Duck, senior forward Arsalan Kazemi led the team with seven rebounds and added five points in 21 minutes.
Kazemi transferred to Oregon from Rice during the summer and sought a hardship waiver from the NCAA so he could play right away instead of sitting out a season. He was finally cleared to play Thursday.
