Charlie McAvoy flubs the puck on the power play, and Chicago converts on the odd-man rush the other way to make it 1-0 Chicago in the first.
The Bruins’ first period woes continue as Dylan Strome is left all alone in front to tip the puck by Tuukka Rask on the PP. 2-0 Blackhawks.
Alex DeBrincat is given too much room, and his perfectly placed shot beats Rask just 17 seconds into the third period to make it 3-0 Blackhawks.
