Sidney Crosby set up Kris Letang's go-ahead goal midway through the second period and Pittsburgh won the fourth Stanley Cup in franchise history by beating the San Jose Sharks 3-1 in Game 6 on Sunday night.
Brian Dumoulin opened the scoring with a power-play goal and Patric Hornqvist added a late empty-netter. Matt Murray made 18 saves to give the Penguins a championship seven years to the day after they beat Detroit for their third title.
Pittsburgh held San Jose to just one shot on goal in the first 19 minutes of the third period to preserve the one-goal lead. The Penguins sealed it when Crosby blocked a shot from Marc-Edouard Vlasic that set up Patrick Hornqvist's empty-netter.
Logan Couture scored the lone goal for the Sharks, who were making their first trip to the final in their 25-year history. Martin Jones made 24 saves and was San Jose's best player for the series.
Crosby was awarded the Conn Smythe trophy as playoff MVP.
