TUCSON, Arizona (Ticker) -- Freshman Ivan Radenovic and Arizona enjoyed their visit by the Oregon schools.
Radenovic scored 15 of his season-high 19 points in the first half as the 12th-ranked Wildcats cruised to a 90-66 Pac-10 Conference victory over Oregon.
Arizona (13-3, 5-2 Pac-10) moved into second place in the conference on the heels of Thursday's 109-75 rout of Oregon State, the Wildcats' highest output of the season. After the Beavers cleared out of the McKale Center, the Ducks faced the brunt of the home team's punishment.
Radenovic scored 11 points in a 3:09 span as part of an 18-0 surge that opened a 36-15 lead 7:40 before halftime. Freshman Mustafa Shakur's jumper capped the tear.
"I work hard and that's the key," Radenovic said. "I had a few open shots and made them. My teammates found me open."
Oregon (9-5, 4-3) suffered its worst loss of the season and fell to 5-21 against Arizona in Tucson. The Ducks had a three-game winning streak stopped.
Radenovic, a 6-10 Serbian, became eligible on December 28 and has averaged 9.9 points and 4.5 rebounds in a reserve role. He had the best game of his young career, also grabbing eight boards.
"Ivan was great to see," Arizona coach Lute Olson said. "He was very aggressive. It's amazing how well he's adjusted for the short period of time he's been here."
The Wildcats forced 13 turnovers in building a 52-27 halftime lead. Arizona only had one miscue and had eight of its 19 offensive rebounds in the first 20 minutes.
"Arizona took control of the game early," Oregon coach Ernie Kent said. "When we didn't block out well and gave up those offensive boards, it hurt. Every mistake that we made, we paid for."
Luke Jackson led Oregon with 20 points, 13 in the second half after the outcome was decided. Andre Iguodala had the chore of guarding Jackson, who committed eight turnovers.
"Andre's job on Luke Jackson was outstanding," Olson said. "I don't know how many Luke got on him, but it wasn't much."
The second half allowed the Wildcats to throw home some highlight-reel dunks for their fans before the reserves finished the game. Hassan Adams, who scored 20 points, and Shakur each were on the receiving end of resounding alley-oop dunks before the benches emptied.
