SUNRISE, Fla. -- After seven seconds: Chicago 1, Florida 0.

After 60 minutes: Florida 5, Chicago 1.

Landon Slaggert got himself a piece of Blackhawks history Saturday, scoring seven seconds into the team's game at the Panthers -- the fastest goal to start a game ever for the Blackhawks, according to the NHL record book.

"That's pretty wild," Slaggert said.

But Florida equalized 5 minutes later, took the lead for good 5 minutes after that and coasted to a 5-1 win.

The Blackhawks became the first team in NHL history to score within the first eight seconds of a game and then not score another goal after that, according to ESPN Research.

Sam Reinhart got his 30th goal of the season and added two assists, and Matthew Tkachuk scored for the third time in the past four games for Florida.

Carter Verhaeghe, Evan Rodrigues and Jonah Gadjovich also scored, and Sergei Bobrovsky stopped 24 shots for the Panthers, who ensured they would remain atop the Atlantic Division.

The win was the 900th regular-season victory as a coach for Florida's Paul Maurice, who is the fourth to hit that milestone. The others: Scotty Bowman (1,244), Joel Quenneville (969) and Barry Trotz (914).

"It's never a good feeling," Florida's Carter Verhaeghe said of giving up the quick goal. "But we kind of just reset from there and played it like a normal game."

The previous Blackhawks record for fastest goal was set by Brent Sutter, who scored eight seconds into Chicago's 9-4 win over Vancouver on Feb. 5, 1995.

Slaggert's score was the fastest goal to start a game in the NHL this season, edging a goal at the nine-second mark by St. Louis' Robert Thomas against New Jersey on Nov. 27.

Ryan Donato won the opening faceoff, then played the puck into the Florida zone. Slaggert -- getting his second goal in just his third game of the season -- skated past two Panthers defenders, collected the puck and beat Bobrovsky with a backhander.

It was the fastest goal allowed at the start of a game in Florida history, three seconds quicker than Mike Knuble's score for Boston against the Panthers on Feb. 14, 2003. And Donato quickly realized that the goal might be historic for Chicago.

"He was saying in the little pile there that it might be the fastest," Slaggert said. "It's kind of funny to hear."

Only seven regular-season goals have been scored more quickly in NHL history, the most recent of those being a goal six seconds into a game by Vancouver's Alexandre Burrows in what became a 5-2 loss to Detroit on March 16, 2013.

There have been four goals scored five seconds into games -- those by Merlyn Phillips of the Montreal Maroons on Dec. 29, 1926, Doug Smail of the Winnipeg Jets on Dec, 20, 1981, Bryan Trottier of the New York Islanders on March 22, 1984, and Alexander Mogilny of the Buffalo Sabres on Dec. 21, 1991.

Three goals have been scored at the six-second mark: Burrows had one, while Henry Boucha of the Detroit Red Wings on Jan. 28, 1973 and Jean Pronovost of the Pittsburgh Penguins on March 25, 1976 had the others.

Slaggert's goal is the eighth scored at the :07 mark of the first period, the NHL said.
