Matthew Tkachuk broke a tie on a fortunate bounce with 5:35 left and the Calgary Flames beat the Chicago Blackhawks 5-2 on Tuesday night for their fourth straight victory.
Tkachuk's centering pass went off the skate of Chicago defenseman Seth Jones and over the shoulder of goalie Marc-Andre Fleury to give Calgary a 3-2 lead. Trevor Lewis and Johnny Gaudreau each added an empty-net goal for the Flames (12-3-5), who sit alone atop the Western Conference.
Dillon Dube and Milan Lucic also scored for Calgary, which has earned at least one point in seven consecutive games. Jacob Markstrom made 19 saves.
Reese Johnson had a goal and an assist - his first two NHL points - to lead the offense for Chicago (6-11-2). Brandon Hagel also scored.
Coming off a 40-save shutout Sunday against Vancouver, Fleury had a tough start to the night, getting beaten twice on the first six shots he faced before slamming the door until late in the third. He finished with 34 stops and fell to 5-8-0.
Both Blackhawks goals were the result of costly turnovers.
After the Flames grabbed the lead just 1:19 into the game, Hagel tied it at 8:57 when Tyler Pitlick coughed up the puck along the sideboards and Hagel whipped a quick shot into the top corner.
Lucic's goal at 13:06 gave Calgary a 2-1 lead after the first period, but Chicago tied it 3:51 into the second on another freebie.
From behind the net, Markstrom's pass attempt to Elias Lindholm went off the heel of Lindholm's stick and was promptly fired into an open net by Johnson.
After that miscue, Markstrom made a string of saves to keep the game tied.
First, he squeezed a dangerous shot from Patrick Kane from 20 feet out as he broke in off right wing.
On his next shift, Kane got a breakaway, only to see Markstrom turn him aside again, getting a blocker on a shot that also ticked off the post.
Later in the period, Markstrom jabbed out his pad to make a skate save on Kirby Dach. Right after that, he acrobatically got across the crease to rob Hagel after he was set up on a 2-on-1.
Dube opened the scoring on Calgary's first shot when he fired a wrister off left wing just over the pad of Fleury.
After a hectic stretch of nine games in 15 days - including a seven-game Eastern road trip - Calgary has three days to recharge before facing Winnipeg.
The Blackhawks host the St. Louis Blues on Friday.
