Patrice Bergeron and Rick Nash scored two goals apiece, leading the Bruins to a 6-2 win and a 1-0 lead in their second-round playoff series with the Tampa Bay Lighting.

David Pastrnak added a career-high 4 assists as the Bruins went into Amalie Arena on Saturday and took the opening game of the series with a convincing win.

Rick Nash scored a power-play goal by tipping a shot from Pastrnak past Lightning goalie Andrei Vasilevskiy, giving the Bruins a 1-0 lead at 17:11 of the first period.

The Bruins jumped out to a 2-0 lead just 42 seconds in the second, when Bergeron scored from the circle off a feed from Pastrnak.

Nash took a drop pass from David Krejci and fired a wrister past Vasilevskiy at 12:33 of the middle period, giving the Bruins a 3-1 lead.

Brad Marchand tipped a Charlie McAvoy slap shot past Vasilevskiy at 3:32 into the third, putting the Bruins ahead 4-2.

A feed from Marchand set up Bergeron for a one-timer at 10:11 of the final period.

DeBrusk tacked on an empty-net goal with 6:19 remaining.

The Bruins and Lightning will meet for game two Monday night in Tampa Bay.
