John Klingberg’s hard shot grazed Alexander Radulov’s stick and went in to give the Stars the win.

The shot that got past Cam Talbot was the 62nd for the Stars, their most since 63 in a five-overtime loss in the 2003 playoffs. The goal was initially give to Klingberg, but NHL announced the scoring change about three hours after the game.

Klingberg finished with three assists.

Pavelski recorded the first playoff hat trick since the Dallas franchise moved from Minnesota in 1993, and the first of his career on his 53rd career postseason goal.

Tobias Rieder tied an NHL record with his third short-handed goal of the playoffs, and Calgary got one in a third straight game against Dallas, for a 4-3 lead early in the third period.

Game 5 on Tuesday.
