The Pittsburgh Penguins reached the Eastern Conference Final by defeating the top-seeded Washington Capitals in six games in the second round. It was Pittsburgh's eighth Stanley Cup Playoff series win against their Metropolitan Division rival in nine tries.
The Tampa Bay Lightning, who eliminated the New York Islanders in five games in the second round, are not as familiar to the Penguins. The teams have played each other once in the postseason, in 2011, when Tampa Bay defeated Pittsburgh in seven games in a first-round series.
The Lightning won all three games this season against the Penguins, but they haven't faced each other since Feb.
