Brandon Saad added a goal and an assist for Chicago, which remained perfect in seven home playoff games this year. Duncan Keith had a tiebreaking score in the third period.
Playing just two days after a Game 7 victory over Anaheim, the Kings got a second-period goal from Tyler Toffoli and outshot the Blackhawks 26-20. But Crawford made a couple of solid stops in another terrific performance.
Game 2 of the best-of-seven series is Wednesday night.
