ZURICH — Benjamin Nissner scored a power-play goal in the third period to help Austria beat Latvia 3-1 at the ice hockey world championship on Tuesday. Austria’s third straight win put it level on points with Switzerland and Finland atop Group A. Tim Harnisch’s second-period goal gave Austria a 1-0 lead before Latvia captain Rudolfs Balcers tied it early in the third with his tournament-leading fourth goal. After Nissner’s go-ahead goal, Vinzenz Rohrer added an empty-netter. In Group B in Fribourg, Norway blanked Italy 4-0 for its second victory and second shutout. Eskild Bakke Olsen, Noah Steen, Christian Kaasastul and Tinus Luc Koblar had a goal each while goaltender Henrik Haukeland stopped all 30 shots he faced. Italy, a newcomer in the top division, remains without a point. Britain plays Hungary in Zurich later Tuesday, and Slovakia meets Slovenia in Fribourg. ___ The Associated Press
