(CALGARY) – Matthew Tkachuk broke a tie on a fortunate bounce with 5:35 left and the Calgary Flames beat the visiting 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 for the Blackhawks. 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. Having won five of six entering Tuesday’s game, Chicago finished its road trip 2-2.
