Vincent Lecavalier, Nate Thompson and Mattias Ohlund -- into an empty net -- also scored. Simon Gagne had three assists and Tampa Bay, coming off a 3-0 loss Wednesday night, rediscovered its high-powered offense to blow the game open with a three-goal first period.
Craig Adams scored for the Penguins, who came out flat and will have two days to regroup for Game 3 at Tampa Bay on Monday night.
For St. Louis, the performance was payback after the diminutive forward was livid that no penalty was called after he was cracked across the face by Zbynek Michalek's errant stick in the second period of Game 1.

The Lightning followed their top scorer's lead with an efficient opening period in which they scored on two of their first three shots, looking much like the team that finished second in the Eastern Conference with 247 goals.
