Evgeni Malkin scored one goal and assisted on another, Matt Murray made 23 saves and the Penguins took a 3-1 series lead in the Stanley Cup Final by beating the San Jose Sharks 3-1 on Monday night.
Malkin helped set up Ian Cole's goal to open the scoring, then added one of his own on the power play to give Murray all the support needed.
Eric Fehr sealed it with a late goal after San Jose made a strong push in the third.
The Sharks were unable to build on their first win in the final, allowing the first goal for the fourth straight game and going more than nine minutes without a shot on goal during one stretch of the second period.
San Jose has yet to lead at any point in the series other than after scoring in overtime in Game 3.
Melker Karlsson scored the lone goal and Martin Jones made 17 saves for San Jose.
Murray stopped Patrick Marleau on a breakaway and saved a one-timer by Joe Pavelski early in the third before allowing his first goal. Karlsson beat him on a rebound of Brenden Dillon's point shot with 11:53 to play.
Two nights after allowing a soft game-tying goal to Joel Ward, Murray was steady throughout to put the Penguins one win from skating off with their fourth Stanley Cup in franchise history. They can do it at home in Game 5 on Thursday night.
