Rantanen had a hat trick and an assist in Game 7 against his former team, propelling the Stars to the second round.

DALLAS (AP) — Mikko Rantanen carried the Dallas Stars past his former team in the first round of the NHL playoffs, punctuated with a hat trick that was part of his historic four-point third period in Game 7.

In Game 6, Rantanen and Roope Hintz made NHL history by becoming the first teammates to score four points in a single period. But that was a footnote in Colorado’s 7-4 win that made Saturday’s Game 7 necessary. So Rantanen sent one better with a hat trick in the final 13 minutes of the game.
