CHAMPAIGN, Illinois (Ticker) -- This effort did not help Indiana's chances for an at-large berth in the NCAA Tournament.
Roger Powell scored a career-high 22 points and Brian Cook added 17 as 16th-ranked Illinois won its 16th straight home game, an 80-54 Big Ten victory over the stumbling Hoosiers.
Indiana (16-10, 6-7 Big Ten) fell for the seventh time in eight road games and suffered its worst loss of the season. The Hoosiers have dropped seven of 10 overall.
The only possible saving grace for Indiana is that two of its three remaining games are at home, with the road contest at last-place Penn State.
"We're sitting here at 6-7, three games left," Indiana coach Mike Davis said. "It would've been a great win here tonight, but we have three games, two at home and one road game. If we win these three games, we will be in the same position as last year at 19-10 and we should be an NCAA Tournament team."
Powell had his second straight big game after scoring 20 points on 8-of-10 shooting on Saturday against Northwestern. Cook finished in double figures for the 21st time this season.
Illinois (19-5, 9-4) took the lead for good with just over eight minutes left before halftime and never looked back. Cook and freshman Dee Brown each had four points as the Fighting Illini closed on an 8-2 tear for a 39-30 halftime edge.
The Hoosiers' Jeff Newton scored an inside basket to open the second half before Illinois answered with nine straight points. Brown's 3-pointer provided a 48-32 cushion with 16:25 remaining.
Sean Harrington's 3-pointer capped a spurt of seven straight points as the Fighting Illini opened a 64-43 cushion with 8:39 left.
Powell made 9-of-13 shots in exploiting Indiana freshmen Bracey Wright's defense. He helped limit Wright to six points.
"We wanted him to be aggressive," Illinois coach Bill Self said. "We told him that. We didn't know who would be guarding him, but it turned out to be Bracey most of the time."
Brown was the third player in double figures for Illinois with 16 points and freshman Deron Williams handed out seven assists. The Fighting Illini had just a season-low five turnovers despite its freshmen backcourt.
"They're freshmen, but they're beyond their years," Self said. "They're not freshmen anymore."
Illinois shot 55 percent (33-of-60) and used its defense to come up with nine steals in comparison to none for Indiana. The Fighting Illini avenged a 74-66 road loss to the Hoosiers on January 18.
Newton was the only Hoosier in double figures with 11 points and Tom Coverdale nailed three 3-pointers for nine points. The Hoosiers shot just 36.5 percent (19-of-52) and had more 3-pointers (10) than baskets inside the arc (nine).
The Fighting Illini also held a commanding 41-24 rebounding edge on the glass as Cook and Powell each grabbed seven. The Hoosiers held a 47-38 edge in the first meeting.
"We're really rebounding the ball much better now," Self said. "But this was a big spread. They really kicked our butts in Bloomington."
It was the worst loss in three seasons for Davis, who has had trouble motivating his players. He decided to keep starters Wright, George Leach and freshman Marshall Strickland on the bench for much of the second half, opting to give minutes to Donald Perry and Sean Kline.
"We're still challenging (guys) right now," Davis said. "That's the biggest problem."
