Simmonds brought the Kings within one 1:20 into the third when he took a feed from Anze Kopitar down low and lifted it over Crawford into the roof of the net, but Crawford was strong down the stretch.
Los Angeles outshot the Hawks, 11-4, in the third period, but Crawford was able to stop 10 of them to maintain Chicago’s lead. Dustin Brown was called for a boarding penalty with 2:47 remaining, cutting into the Kings’ desperation attack time.
Toews put Chicago on the board with a wrister from the right circle at 11:30 of the opening period, but the Kings tied it 1:34 into the second.
