(AP) -- Draymond Green had 22 points and 10 rebounds to help No. 6 Michigan State beat Iowa 95-61 on Tuesday night for its 15th straight win.

The win gives the Spartans (15-2, 4-0 Big Ten) their longest winning streak since the 1998-99 season, when they won 22 in a row before losing to Duke in the national championship game.

The Hawkeyes (10-8, 2-3) have been routed in two straight games they also lost to Ohio State - after beating Wisconsin and Minnesota on the road.

Aaron White scored 15 points and Devyn Marble had 12 for Iowa.

Michigan State went on a 16-0 run late in the first half and had a 14-0 spurt midway through the second.

During the second burst, Iowa coach Fran McCaffery was called for a technical for berating an official. McCaffery then directed his anger toward his players, slamming a chair in their timeout huddle and screaming in their faces.
