The Roadrunners gave the Ducks more than they expected, leading for much of the first half. A Tony Woods' go-ahead running hook midway through the first started the Ducks on a 21-7 run and Oregon (6-1) pushed it to 11 points at the break.
Oregon struggled to cover the Roadrunners early, giving up a pair of uncontested lay-ups in the opening minutes, allowing Texas-San Antonio to make six of their first seven shots.
"When we get out and extend and we're not fully aware of where the ball is, our defensive can look pretty bad. They caught us in some of those situations tonight," head coach Dana Altman said.
"He's fitting in right along and picking it up off the bat. That's going to be huge for us, because he's a big help," center Tony Woods said. Kazemi, who had been averaging just below six points per contest, set a career-high scoring 20 points.
"I think every game that goes by I get better and get more comfortable with my new teammates. Hopefully every game I get better," Kazemi said.
Kazemi was also aggressive defensively, jumping into the passing lanes for five steals and blocking three shots.
"Arsalan created a lot of havoc with his feet and his quick hands. I was really pleased with is effort," Altman said.
The rotation change relegated previous starter Woods to the bench to start the game. Woods, who had played just 16 combined minutes in the previous two games due to foul trouble, responded well, scoring 15 points on 6-for-10 shooting. Woods finished with just three fouls.
"My mentality is still to do whatever I can to help my team win games," Woods said of coming off the bench.
The Ducks got the ball down-low early and often, which according to Woods was a "big emphasis", the strategy resulted in a season-high 63 percent shooting.
"We shot the ball very well tonight. It was a better offensive game for us," Altman said.
Guard Johnathan Loyd stressed the importance of clearing the defensive glass during Wednesday's time with the press and the team did so in emphatic fashion holding their opponent to just three offensive boards and two second chance points.
"They [UTSA] kind of got back. They didn't go to the boards," Altman said. "They're not a good rebounding team. It was better, but not where it needs to be."
With the improvement, also came some teaching points, namely carelessness with the basketball and closing out on open shooters. The Ducks turned the ball over 18 times and the Roadrunners shot over 56 percent from the field.
"Really disappointed with our bite on the defensive end. We were on our heels it felt like," Altman said. "A lot of things defensively to work on."
Willie Moore missed the game with a sprained ankle he suffered in practice, but Altman called the injury minor and was hopeful that he'd be ready for Saturday's game versus Arkansas-Pine Bluff.
