Boyle scored 8:52 into the final period to give the Lightning a four-goal lead. After deflecting Sheldon Keefe's shot away from the net, Boyle wrapped around the right side of the net and wristed the puck over backup goaltender Tomas Vokoun.
He also helped set up Keefe's eventual game-winner with 2:34 remaining in the second period. Boyle dumped the puck to Brad Richards along the right boards, from where he centered it to Keefe in the slot. Keefe controlled the bouncing puck, then fired a slap shot off Mike Dunham's blocker and into the net.
Acquired from Florida on Jan. 7, Boyle got his first goal with the Lightning in a 3-2 triumph over the Panthers on March 2. Since then, he has three goals and four assists in his last four games.
Boyle also registered an assist on Richard's 16th goal that extended Tampa Bay's lead to 3-1 at 1:40 of the third period.
Richards has five goals and seven assists during a six-game points streak. Since wingers Martin St. Louis and Fredrik Modin went down with injuries in late January, Richards has carried the Tampa Bay offense with six goals and 10 assists in 14 games.
