The Dallas Stars advance to the second round of the NHL playoffs, beating the Colorado Avalanche 4-2 in Game 7.Mikko Rantanen assisted on Wyatt Johnston's tiebreaking power-play goal with 3:56 left before completing a third-period hat trick with an empty-netter as the Dallas Stars beat the Colorado Avalanche 4-2 in Game 7 on Saturday night to wrap up the first-round Western Conference playoff series.

Rantanen is the first player in NHL history to score a hat trick in the third period of a Game 7, and the first to record multiple four-point periods in a single postseason after also achieving the feat with a goal and three assists in the second period of Game 6.

The Stars will either advance to the second round or see their season end Saturday night at American Airlines Center.
