MADISON, Wisconsin (Ticker) -- After an uncharacteristically slow start on defense, No. 18 Wisconsin recovered for a customary result.
Devin Harris scored 21 points as the Badgers posted their 22nd straight home win, a 77-64 victory over Michigan State in a Big Ten Conference contest.
Wisconsin allowed Michigan State to hit its first eight shots, but reserve Clayton Hanson scored all nine of his points as the Badgers used a 24-5 run to erase an early 12-point deficit. Boo Wade capped the surge with a layup to give Wisconsin a 29-22 lead 5:40 before halftime.
"Grit. They didn't get down," Wisconsin coach Bo Ryan said about his club. "I hate to even look at it as a comeback, but I guess that's the term you have to put out.
Wade finished 15 and six rebounds for Wisconsin (11-2, 2-0 Big Ten), which entered the game holding opponents to under 42 percent from the field.
Chris Hill and backcourt mate Kelvin Torbert each scored 13 points for Michigan State (5-7, 0-1), which lost for the sixth time in its last eight games. The Spartans committed 17 turnovers.
Despite being one of the nation's biggest disappointments, the Spartans are trying to find some positives.
"There were a few things that I was pleased with and a few things that I was disappointed with," Michigan State coach Tom Izzo said. "We were off to a great start. I thought we played some of our best defense early, forget the offensive part of it. We were active, we were digging, we were getting turnovers."
Paul Davis contributed 12 points for the Spartans, whose miscues led to 25 points for the Badgers. Michigan State, which entered averaging 15.9 turnovers per game, made all 13 free throws.
But the Badgers went to the line 35 times, making 24. Zach Morley made 6-of-8 free throws and finished with 13 points for Wisconsin, which outscored Michigan State in the paint, 34-16.
"I was really frustrated with that today," Izzo said about the disparity in free throws. "I thought there was a lot of physical play inside. I think that they (Wisconsin) do a great job with their bodies - hands are always up, bodies are always hitting. They really do a good job of that and we didn't handle it well."
Torbert made a layup to give the Spartans a 17-5 lead 4:57 into the contest and 49 seconds later Maurice Ager misfired from behind the arc, ending Michigan State's string of successful shots. Chris Hill and Torbert each missed shots before Hanson triggered the run with a layup with 12:23 left in the half.
Hanson, who made all three of his shots in the first half and played just four minutes after the break, drained a 3-pointer to give the Badgers the lead for good, 25-22, with 6:36 remaining.
"We just started to execute," Ryan said. "Just grinding gears and not getting a whole lot, not going anywhere and finally we just got things. We let the clutch out, put it in gear and it was nice to see."
Harris capped a 10-2 burst with a pair of free throws to give the Badgers a 39-27 advantage 1:53 before the break. The first eight points of that run were scored in the paint.
The Spartans trimmed the deficit to seven points 4 1/2 minutes into the second half, but never threatened as Wisconsin shot better than 55 percent (10-of-18) in the final 20 minutes.
