EAST LANSING, Mich. (AP) — Draymond Green had 22 points and nine 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.
