DALLAS -- Wyatt Johnston scored three power-play goals for the third hat trick of his career, and the Dallas Stars snapped the St. Louis Blues’ four-game win streak with a 6-3 win at American Airlines Center on Sunday.

Roope Hintz grew Dallas’ lead to two goals off a pass from Robertson just over a minute into the second period, but St. Louis cut the lead back to 4-3 when Nathan Walker batted in a loose puck after Jake Oettinger stopped a breakaway. Hintz had his second consecutive four-point game.
