The Buckeyes' point total was a season low, but their defensive effort made it plenty high enough.
The OSU frontcourt tandem of Jantel Lavender and Star Allen both posted double-doubles as the 16th-ranked Buckeyes (13-2, 4-0) beat the Badgers (12-4, 2-3) for a 13th straight time. Ohio State took sole possession of first place in the Big Ten after Indiana lost to Minnesota 70-62.
In Madison, Lavender had 16 points and 15 rebounds for her 15th double-double of the season while Allen added 11 points and a dozen boards to reach double figures in both categories for the second time this season and the second game in a row.
Adding scoring punch was OSU guard Ashlee Trebilcock, who scored 11 points.
One weather report had the outdoor temperature at 5 degrees Fahrenheit in Wisconsin while the official stats showed the hosts making just 13 of 51 shots from the field, a percentage of 25.5 that represented the team's lowest in Kohl Center history.
Ohio State made 19 of 56 field goals (33.9 percent).
"It was a tough shooting night and we had some good looks," Wisconsin head coach Lisa Stone told reporters afterward. "It just did not go down."
Aside from harassing the Badgers shooters, the Buckeyes also managed 10 steals, including four by Shavelle Little.
The visitors also dominated the boards by a 46-30 margin.
"We've got some quick jumpers and I think they were relentless on the boards tonight," Ohio State head coach Jim Foster said. "On the offensive end, I thought Star really created a lot of opportunities for us with those offensive rebounds. When you have two players with double figure points and double-figure rebounds on a night when it's not going in easy, that's a good thing to have."
Lin Zastrow scored 11 points to lead Wisconsin.
The Buckeyes entered the game leading the Big Ten in scoring at 72.1 points per game while the Badgers' defensive average of 54.2 points allowed per game was best on that side of the ledger.
Ohio State's previous season low for points was 63 twice, a 63-45 win over Hartford and a 72-63 loss to North Carolina.
