MADISON, Wis. -- Stephanie Mavunga scored 21 points with 10 rebounds, Kelsey Mitchell set an NCAA record by hitting a 3-pointer in her 81st straight game and No. 18 Ohio State defeated Wisconsin 68-55 on Saturday.

The game was delayed 15 minutes in the third quarter as Ohio State's Makayla Waterman was fitted with a neck brace and taken off on a stretcher. Waterman was injured falling to the court battling for a rebound under the Ohio State basket at the 2:08 mark and the Buckeyes leading 41-38. She moved a hand and shared a smile with her teammates before being wheeled away.

After the delay, Asia Doss hit a 3-pointer to give Ohio State a 44-38 lead entering the fourth quarter. After a Wisconsin basket, Mavunga had a 3-point play to start a 9-1 run for a 12-point lead. Mitchell had two baskets in an 8-0 run that made it 66-50 with two minutes to go.

Ohio State had a 16-0 run in the first quarter that included a Mitchell 3-pointer that broke her tie with former Tennessee-Martin player Heather Butler for the most consecutive Division-I games with a trey.

Mitchell finished with 16 points and Linnae Harper had 15 with 11 rebounds for the Buckeyes (19-5, 8-3 Big Ten).

Wisconsin (9-16, 2-10), playing before a season-high crowd of 6,623, got 20 points from Marsha Howard and 15 with 13 boards from Cayla McMorris.
