UP NEXT: Chicago hosts San Jose on Wednesday night at the United Center (TICKETS).
The two teams played a scoreless opening frame, putting forth seven shots apiece, including a Drake Caggiula partial breakaway chance early on that beat Jake Allen and found iron but directed away from danger.
St. Louis found the opening goal at the 6:41 mark of the second period off a scramble in front of the Blackhawks net. Robert Bortuzzo collected a bouncing puck as he slid back towards the goal line aside Crawford's net, puting a low-angle chance above the sprawled out Blackhawks netminder for a 1-0 lead.
Alex Pietrangelo doubled the lead early in the third, again from a low angle. Jaden Scwartz slid a feed across the slot through traffic to the awaiting Pietrangelo at the bottom of the circle, where the defenseman put a quick wrister past a diving Connor Murphy and Crawford for a 2-0 lead at 5:37.
Chicago pulled Crawford with three minutes on the clock in search of the equalizer, but couldn't solve Allen in net and fell 2-0.
