CHICAGO (Ticker) -- Illinois continues to play up to its lofty ranking.
Luther Head scored 23 points as the top-ranked Fighting Illini enjoyed another laugher with an 83-66 victory over Oregon.
Sparked by Head, who paced all five starters in double figures, the Fighting Illini (9-0) won their ninth straight game this season by double digits. They have won by an average of 16.7 points.
Head made 5-of-6 shots from the field in the first half, helping Illinois open a 43-29 advantage. The senior guard finished 8-of-10 from the field.
"It's good to have the No. 1 ranking," Head said. "We don't really pay attention to it, we just want to play like we're No. 1 and keep winning."
"He was just so solid," Illinois coach Bruce Weber said of Head. "It's about as good scoring wise as he's been. A great game for him."
Deron Williams added 17 points and Dee Brown 13 for Illinois, which shot 58 percent (29-of-50) from the field.
Bryce Taylor scored 19 points to pace the Ducks (4-1), who fell to 2-22 all-time against top-ranked teams.
Illinois drew praise from Oregon coach Ernie Kent.
"Obviously that is a very good basketball team," Kent said. "They're so well-coached, they're so experienced and they're playing with such a swagger and confidence. Every ranking they've gotten they deserve. They've got a chance to have a special year."
The latest victory for the Illini never was in doubt as they scored the game's first six points and raced to 25-11 with 10:32 left in the half on Williams' three-point play.
A 7-2 surge by the Ducks got the lead under double figures, but Williams drilled a 3-pointer and Brown made a layup to rebuild the advantage to 41-26 with just over a minute left in the half.
"I think we come out with a lot of energy," Weber said. "I think we hit people with a little bit of shock treatment and get after them."
Roger Powell Jr. added 12 points and James Augustine 10 for Illinois, which used an 8-2 run to start the second half to put the game out of reach. The Illini led by as many as 21 points late in the contest.
Freshman Malik Hairston contributed 14 points for the Ducks, who shot 43 percent (23-of-57). They went 8-of-22 from the arc.
