Jason Dickinson scored twice, Petr Mrazek made 40 saves and the Chicago Blackhawks beat the Calgary Flames 3-1 on Tuesday.

Seth Jones also scored for Chicago, and Joey Anderson had two assists. Connor Bedard, who wrapped the blade of his stick in rainbow-colored Pride tape for warmups on Pride Night, picked up his team-best 35th assist.

Blackhawks rookie Landon Slaggert had two assists for his first points in his sixth NHL game. But he was turned away by Calgary defenseman MacKenzie Weegar on a prime scoring opportunity, and then came up empty on another chance.

The horn sounded after Slaggert appeared to score in the third period, but a review showed the puck never went into the net. The 21-year-old forward smiled as he stood in front of the Chicago bench before the decision was announced by an official.

The last-place Blackhawks improved to 6-4-0 in their last 10 games. They have just 21 victories in 72 games on the season.

The Blackhawks are at Ottawa on Thursday night for the opener of a three-game trip.
