Corey Crawford made 21 saves, and the Blackhawks generated just enough offence to improve to 7-1 at home in the playoffs. Crawford faced only two shots in the first period and stopped one.
Game 2 is scheduled for Sunday.
Jonathan Quick stopped 34 shots, and Justin Williams scored for Los Angeles, which has won just one of seven road games in the playoffs. Williams has scored the last three goals for the defending Stanley Cup champion Kings. He was responsible for all of Los Angeles' offence in a 2-1 victory over the San Jose Sharks in Game 7 of the second-round series on Tuesday.
BRUINS 3, PENGUINS 0
PITTSBURGH (AP) — David Krejci scored two more goals during his torrid post-season and Boston shut down Pittsburgh in the opening game of the Eastern Conference finals.
Pittsburgh came in averaging a league-high 4.27 goals in the playoffs but couldn't solve Rask. The Penguins hit the post six times and seemed a little bit off following an eight-day break between rounds.
The Bruins were coming off a similar layoff but had no such issues. Krejci scored early, and the Bruins handed Pittsburgh its worst loss of the playoffs.
Game 2 is Monday night.
Tomas Vokoun stopped 27 shots but surrendered a soft goal to Krejci, and Pittsburgh's sizzling power play cooled off. The Penguins came in leading playoff teams with the man advantage, scoring on 28 per cent of their chances, but they went 0 for 4 in the opener.
