CHICAGO (Ticker) -- After opening the season with lightweights, Arkansas was not ready for a ranked team.
Deron Williams scored 11 of his 17 points in the first half when No. 11 Illinois built a 15-point lead en route to an 84-61 victory over Arkansas.
Illinois (4-1) was coming off an 88-81 loss to North Carolina on Tuesday in the ACC-Big Ten Challenge and took out its anger on Arkansas, storming to a 23-9 lead in the first 11 1/2 minutes and coasting the rest of the way.
Williams, who had a career-high 22 points in Tuesday's loss, could have approached that total again but was taken out of the game by coach Bruce Weber with five minutes left and Illinois leading by 27 points.
"With Brian Cook gone, I have to take on some of the scoring load," said Williams, who was 6-of-11 from the field.
Dee Brown, Williams' fellow sophomore backcourt partner, capped the 10-0 run which gave Illinois its 23-9 advantage with a 3-pointer, but struggled again from the floor. The preseason Big Ten Player of the Year, Brown hit just 4-of-12 shots and finished with 13 points after converting only 3-of-17 shots in the loss to North Carolina.
"I am just not shooting the ball well," Brown said. "But I just need to continue to have confidence. The best thing about our team is all I have to do is run and get other people open."
Jonathon Modica scored 20 points to lead Arkansas (4-1), which shot just 33 percent and committed 21 turnovers.
"Those guys move the ball well," Modica said. "They played good defense and played together. That's something we need to learn to do."
The Razorbacks were off to their best start in five years, but the wins came over Nicholls State, Grambling, Jacksonville and Oral Roberts.
After opening a 40-25 halftime lead, Illinois scored the first six points of the second half as Williams caught a lob underneath for a reverse layup and set up Roger Powell for a layup - one of his 10 assists.
The game was a far cry from last season's meeting when Illinois held on for a 62-58 victory at Little Rock. But this one was held at the United Center, where the Fighting Illini have won nine straight.
