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.

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.

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.

For one night anyone, it felt like old times on Causeway. With bad blood spilling all over TD Garden between two teams that played a week ago, the Boston Bruins sprinted to a 4-0 second period lead and hung on for a 6-2 victory against the Tampa Bay Lightning.
