The new Top 25 polls were released on Monday, and Indiana made sizable jumps in both after two blowout wins last week.
The Hoosiers (17-3, 7-0 Big Ten) moved from 25th to 17th in the USA Today/Coaches Poll and went from unranked in the AP poll to No. 19.
Indiana improved to 7-0 in conference play in emphatic fashion, beating the state of Illinois' two Big Ten teams by a combined 66 points. The Hoosiers throttled Illinois 103-69 on Tuesday, and ran Northwestern out of Bloomington with an 89-57 win on Saturday.
The Hoosiers take their 12-game winning streak into Madison for a meeting with Wisconsin on Tuesday. Indiana beat the Badgers 59-58 in Bloomington earlier this season.
