Andrew Shaw scored twice and Marian Hossa had a goal and two assists for the Blackhawks, who trailed 4-2 with 8:46 left in the second period. It was Hossa's 100th goal with Chicago and No. 439 for his career.
The Senators scored three times in a span of four shots in the second, but were unable to hold off the suddenly high-scoring Blackhawks. Kyle Turris and Milan Michalek each had a goal and an assist in Ottawa's fourth loss in five games.
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
