DETROIT (AP) -- Jason Spezza and Bobby Ryan scored two goals each as the Ottawa Senators routed Daniel Alfredsson and the Detroit Red Wings 6-1 on Wednesday night.
Alfredsson was held without a point by his former team. The Swedish winger spent 17 seasons with the Senators before signing a one-year deal with the Red Wings in the offseason.
Eric Gryba and Jared Cowen also scored for the Senators, who had three goals on eight shots against Jimmy Howard before the Detroit goalie was taken out in the first period.
Craig Anderson made 31 saves for Ottawa.
Spezza has seven goals on the season, trailing only Washington's Alex Ovechkin, who leads the NHL with nine.
The Senators won at Detroit for the first time since 2006, although this was only their third road game against the Red Wings since then.
At Buffalo, Milan Lucic had two goals and an assist, and Torey Krug also scored twice to help the Boston Bruins beat the reeling Sabres 5-2.
Dougie Hamilton also scored for Boston. The Bruins are 6-2 overall and have won their first four road games for the first time since 2010.
Nikita Zadorov and Cody Hodgson scored for Buffalo. At 1-9-1, the Sabres are off to their worst start in club history. They are winless in their first seven home games.
Boston left wing Loui Eriksson had to be helped from the ice after a late hit from Sabres enforcer John Scott in the third period. Scott then fought Adam McQuaid and was given a match penalty.
