NOTES:Hronek is the first Red Wings defenseman with six goals in a six-game span since Reed Larson scored seven in four games, including a hat trick, in January 1981. … Hronek tied the Red Wings record for longest goal streak by a defenseman (Mathieu Schneider, 2005-06; Nicklas Lidstrom, 2000-01; Larson, 1980-81). … Detroit forward Michael Rasmussen played his 200th NHL game. … The Red Wings had a moment of silence before the game to honor Hall of Famer Borje Salming, who passed away Thursday. Salming played his final 49 games for Detroit in 1989-90, joining the team in the same summer they drafted Lidstrom, another Swedish Hall of Fame defenseman. … Clayton Keller had an assist, giving him 12 points (seven goals, five assists) in eight career games against Detroit.
