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.
That was something I've been dreaming of, something I've told myself before the third period I was going to do ... It was an amazing feeling. It's hard to describe. I didn't believe it went in at first but when I saw all the reaction and all the fans going crazy and my teammates going crazy, it's just an unbelievable feeling. I didn't know what to do. I didn't know whether to jump or just skate and do a Theo Fleury. I don't think I'm the same caliber player he is so I couldn't do it.
