Bruins forward Trent Frederic avenged Mark Kastelic on Tuesday by scrapping with the Tampa player who injured him, Emil Lilleberg.

Even though a recent report saying the Boston Bruins are an un-unified team was already deemed baseless, Trent Frederic completely dispelled it with just a few punches.

David Pastrnak had a goal and two assists and Parker Wotherspoon scored his first NHL goal to help the Boston Bruins open a four-goal lead and hold on to beat the Tampa Bay Lightning 6-2.

A poor start doomed the Lightning, as they allowed four unanswered goals in the opening 26:05. Although they pushed hard in the final 14 minutes of the second period and reduced the deficit to two, they were unable to pull themselves out of the hole they dug.

Coach Jon Cooper told media postgame that slow starts plagued his team throughout the three-game road trip that ended Tuesday—Tampa Bay trailed in all three games against the New Jersey Devils, Pittsburgh Penguins and Bruins despite finishing the trip with a 1-1-1 record.

The Lightning played without their leading goal-scorer, top center Brayden Point, who was scratched for missing a team meeting prior to the morning skate. It forced the team to scramble just to get enough players to fill its roster, recalling 22-year-old forward Jack Finley from AHL Syracuse to make his NHL debut as the 12th forward.

Boston Bruins forward Mark Kastelic suffered an upper-body injury during the club's Jan. 9 contest against the Tampa Bay Lightning and has not played since. This was after he was cross-checked in the head by Lightning defenseman Emil Lilleberg. Kastelic also dropped the gloves with him following it.

Under duress from Charlie Coyle, Victor Hedman lost the puck just inside his left point position and Poitras pounced on it, bursting up ice on a 2-on-1. He smartly waited out Nick Perbix’s belly-flop slide and made a pretty pass around the defenseman’s skates to Trent Frederic for a redirection at 4:24, Frederic’s seventh of the year.

Bruins forward Mark Kastelic was cross-checked in the mouth toward the end of last week’s 4-1 loss to the Lightning in Tampa Bay, and when these teams met again Tuesday night at TD Garden, the B’s made sure Bolts forward Emil Lilleberg paid for his actions.

David Pastrnak and Pavel Zacha each logged a goal and two assists and Jeremy Swayman tied his career-high mark with 43 saves as the Boston Bruins beat the visiting Tampa Bay Lightning 6-2 on Tuesday night.
