Joe Mullen and Joe Nieuwendyk scored first-period goals and Hakan Loob stifled a Chicago comeback midway through the third period as the Calgary Flames downed the Chicago Blackhawks 5-2 Saturday night to take a 2-1 lead in the Campbell Conference finals.

Mullen capitalized on a mistake by goaltender Alain Chevrier and rifled in a 20-footer from the slot at 4:11. Nieuwendyk took a diagnonal pass from Rob Ramage during a power play, got around defenseman Steve Konroyd and shoveled the puck past Chevrier at 14:57.Chicago, which was outshot 11-3 in the first period, got back in the game in the second on goals by Konroyd and Troy Murray sandwiched around a power-play goal by Theoren Fleury.

The Blackhawks stormed the Calgary end in the third period, outshooting the Flames 7-0 in the first nine minutes, but were unable to get the tying goal past Mike Vernon.

Loob's goal came on Calgary's first shot of the final period and stopped the Blackhawks' cold. Gary Roberts came out of the right corner into the slot and fired a 25-foot slap shot that hit Loob's right skate and deflected past Chevrier.
