Captain Mark Stone had a hat trick and the Vegas Golden Knights scored four unanswered goals in the second period in a 9-3 rout of the Florida Panthers on Tuesday to win the franchise’s first Stanley Cup title.

Alec Martinez triggered the four-goal outburst midway through the second period in Game 5 before Reilly Smith, Stone and Michael Amadio added goals to extend the lead to 6-1.

Stone completed his second career postseason hat trick with an empty-net goal to help Vegas capture the Stanley Cup in its sixth season. Only the 1983-84 Edmonton Oilers won the Cup in fewer seasons (five).

Florida played without star forward Matthew Tkachuk, who was sidelined with an injury he suffered in Game 3.

Tkachuk, who led the Panthers with 11 goals and 24 points this postseason, went into the NHL’s concussion protocol after he absorbed a crushing hit from Vegas forward Keegan Kolesar in Game 3 and missed much of the third period in Game 4.
