Cooke, No. 1 South Carolina women beat No. 22 Tennessee

COLUMBIA, S.C. >> Zia Cooke scored 20 points Sunday, and No. 1 South Carolina used its relentless defense to put away No. 22 Tennessee 69-48 for its 15th straight win.

Boston finished with 10 points, five rebounds, two blocks and two steals.

The Wolverines (14-7, 5-5 Big Ten) got their first win over a ranked opponent this season. Amy Dilk added 14 points and six assists, and Akienreh Johnson had 11 points and seven rebounds.

Alexis Sevillian led Iowa with 15 points. The Hawkeyes (18-4, 9-2) had won nine in a row.

NO. 23 NORTHWESTERN 82, PENN STATE 59 >> Lindsey Pulliam and Veronica Burton scored 19 points apiece, leading Northwestern to the road win.

Abbie Wolf had 15 points for the Wildcats, who moved into a tie with Iowa atop the Big Ten, a halfgame in front of Maryland.

Northwestern (19-3, 9-2) outscored Penn State 29-7 in the third quarter.
