Stephen finished with five points and 11 rebounds, while Morgan Paige netted a game-high 33 points and Jacki Gulczynski added 16 for the Badgers (10-11, 2-6 Big Ten), who have won two of their last three.

Wisconsin raced out to the early lead as Gulczynski sank three shots from beyond the arc and Paige added two more 3-pointers during a game-opening 17-6 run.
Penn State answered with a 6-0 push to get back within 17-12 before Wisconsin scored nine of the next 12 points to reopen a double-digit lead, 26-15, with 6 1/2 minutes left in the first half.
