MADISON, Wis. (AP) -- Nigel Hayes scored 14 of his 21 points in the second half, Ethan Happ had 20 points and No. 11 Wisconsin beat No. 23 Maryland 71-60 in a choppy, foul-filled game on Sunday.
   The Badgers (22-5, 11-3) overcame 27 points from Terrapins guard Melo Trimble to snap a two-game losing streak and stay in a tie atop the Big Ten with Purdue.
   Bronson Koenig scored all nine of his points in the second half, giving the Badgers a lift with his jump shot after the senior missed a game with a left calf injury. Wisconsin shot 51 percent in the second half.
   Wisconsin pulled away slowly, turning a six-point halftime deficit into a 12-point edge with 3 minutes to go in a game that lacked flow because of frequent whistles.
   The teams combined for 48 fouls, 25 for Maryland (22-5, 10-4).
