MADISON, Wis. -- Ethan Happ had 20 points and 12 rebounds, and helped spark a 17-0 run that allowed Wisconsin to roar back from a double-digit deficit in the second half of a 69-60 win on Sunday night over Illinois.

Happ, an athletic 6-foot-9 freshman, had three steals during the decisive run for the Badgers (17-10, 9-5 Big Ten), who avoided a potentially damaging loss to their NCAA tournament resume.

Wisconsin rallied from a 13-point deficit with about 12 minutes left. It was the team's best comeback win since overcoming a 15-point deficit in the second half at home to an unbeaten and No. 1 Ohio State on Feb. 12, 2011.

Nigel Hayes scored 13 of his 17 points in the second half after being held without a field goal in the first half.

Malcolm Hill scored 20 points and Kendrick Nunn added 15 for Illinois (12-15, 4-10). The high-scoring duo hit all the tough shots until the Illini became unglued in the second half.

Illinois went more than seven minutes of the half without a field goal, and coach John Groce appeared unhappy at times with the officials with a foul disparity favoring Wisconsin.

The Illini were whistled for 19 fouls in the second half to seven for Wisconsin.

Happ, Hayes and guard Bronson Koenig seized on almost every opportunity, a stark contrast to the first half. The Badgers shot 8 of 28 from the field and 1 of 13 from the 3-point arc before halftime, and the slump stretched early into the second half.

Trailing 46-33, Hayes got the run started with a jumper with 11:55 left.

Michael Finke finally ended the Badgers' surge with a dunk with 5:09 left to get Illinois within 50-48.

But in between, the Illini missed six field goals, two foul shots and committed turnovers on four straight possessions.
