Draymond Green had 20 points and 10 rebounds, and Keith Appling added 20 points to help No. 7 Michigan State defeat No. 15 Wisconsin 69-55 last night.

The win moved the Spartans back into a tie with No. 6 Ohio State atop the Big Ten standings.

It was the Spartans’ sixth victory over a ranked team this season, the most in Division I.

Michigan State’s margin of victory was its largest in the series since Feb. 12, 2000.

The Spartans (21-5, 10-3) have won four straight games — the longest active streak in the conference — and six of their past seven.

Michigan State shot 52.2 percent against a team that hadn’t allowed an opponent to shoot 50 percent once this season and was giving up a nation-low 50.3 points a game. And the Spartans held Wisconsin to 34 percent shooting.

The Badgers (19-7, 8-5) had won seven of their past eight games, including their previous four road games, after opening the Big Ten season with three straight losses.

Ryan Evans scored 17 points for the Badgers. Jordan Taylor missed 10 of 13 shots and was held to 13 points.
