CALGARY—Colin Fraser knocked a clearing pass out of the air, leading to Ben Eager’s go-ahead goal at 5:52 of the third period in the Blackhawks’ 3-1 victory over the Calgary Flames Thursday.After Fraser intercepted the puck off the stick of Flames defenseman Adam Pardy, Tomas Kopecky controlled it in the slot and had his shot deflect off Eager’s knee and past goalie Miikka Kiprusoff.Calgary, coming off a 9-1 loss in San Jose on Monday night, tied it with 1:29 left in the second on a power play, striking on what became essentially a two-man advantage when Fraser’s stick broke.Jarome Iginla threaded a pass to Dion Phaneuf, whose slap shot was partially stopped by goalie Antti Niemi. Jamie Lundmark was at the side of the net to whack in the rebound.Eager has two goals in two games against Calgary.Patrick Kane and Duncan Keith also scored for the Hawks (35-12-4), who remained two points behind San Jose for the overall NHL lead.
