What happened: Mitch Marner scored three goals in the Vegas Golden Knights' Game 3 victory over the Anaheim Ducks, marking the first Stanley Cup playoff hat trick of his career. Vegas led 4-0 in the contest, with Marner's second goal of the night singled out as a highlight-reel finish. The performance moves Marner to second in postseason goals with six.

Why it matters: The hat trick is a milestone moment for Marner, who joined the Golden Knights and is delivering on the postseason stage in a way he had not previously reached in his career. Vegas asserting a Game 3 lead shifts the series tone against Anaheim and reinforces Marner's role as a top-line postseason driver. His emergence as a goal-scoring threat reshapes how opposing defenses will plan against the Knights' top six.

What to watch: Watch whether Marner can extend his scoring run into Game 4 and whether Anaheim adjusts its matchups to contain Vegas's top line. The series score and Marner's usage in special-teams situations are the next markers to track.
