Matthew Tkachuk opened the scoring for the Western Conference-leading Flames, who have won the first two games of an Eastern Conference road trip.

Flames goalie Mike Smith made 26 saves.

Josh Bailey scored for the Islanders, who lost for the third time in four games — a skid that began at Calgary last Wednesday — to fall into a tie for first place in the Metropolitan Division with the Washington Capitals.

Islanders goalie Robin Lehner recorded 24 saves.

After a scoreless first period, the Flames took the lead on a power-play goal by Tkachuk 2:57 into the second. Elias Lindholm, stationed in a face-off circle, fired a shot into the crease. Tkachuk, in one motion and despite being parallel to the net, managed to knock the puck down, regain control and tuck a shot through his legs and under Lehner’s legs.
