Brad Marchand Tyler SeguinThe Penguins were supposed to be unbeatable. Somebody must have forgotten to tell Tuukka Rask.

Rask, the Bruins goaltender who faced so much pressure when he took over for onetime Stanley Cup hero Tim Thomas, is building his own legacy after another sterling performance in Game 4 of the Eastern Conference finals against the Penguins on Friday. Rask stopped all 26 shots he faced and received support from his teammates in a hectic final minute as the Bruins complete the sweep of the mighty Penguins. The Bruins are heading to the Stanley Cup Final for the second time in three years, but this one feels just as new and unfamiliar as 2011.

Adam McQuaid scored the only goal of the night with a slapshot past Pittsburgh goalie Tomas Vokoun in the third period. The last 15 minutes turned into a defensive clinic by the Bruins, and it is almost as fun to relive in pictures as it was to watch in real time.
