Teddy Purcell wasted little time after the opening face-off, as he scored the Lightning’s first goal in less than a minute to give Tampa Bay the early momentum.
Boston responded nearly seven minutes later when Milan Lucic netted the Bruins first goal of the game, which was followed up by a David Krejci score nearly 10-minutes later.
The Bruins took their lead into the first intermission, but their Eastern Conference Finals celebration was short lived, as Tampa Bay responded with two more goals in the second period, thanks to Martin St. Louis and Purcell.
Tampa Bay then stretched their one-goal lead to two, when Steven Stamkos scored his first goal of the contest. Afterward, Boston and Tampa Bay started trading goals, as Krejci scored his second and third to complete the hat trick, while St. Louis scored his second goal of the contest.
Tim Thomas saved 21-of-26 shots between the pipes, while Lightning goaltender Dwayne Roloson saved 16-of-20 shots.
Tampa Bay earned their third victory of the series and forced a Game 7 on Friday at the TD Garden. The winner of Game 7 will advance to the NHL Stanley Cup Finals against the Vancouver Canucks.
