Key moment: Although the Sharks played a solid first period, they found themselves trailing again when Cole scored the first playoff goal of his career. In fact, Cole's goal was his first in 104 games (regular season and playoffs combined), dating to March 26, 2015, against the Carolina Hurricanes.
After taking a pass from Malkin, Kessel carried into the Sharks zone and took a bad-angle shot from the right circle. Goaltender Martin Jones made a blocker save but left a sloppy rebound in the left circle that Cole fired home for a 1-0 Pittsburgh lead.
Unsung player of the game: Penguins defenseman Brian Dumoulin played another strong game, again helping partner Kris Letang hold the Sharks' top line with Joe Pavelski and Joe Thornton (and multiple left wings) in check.
What's next: The Stanley Cup will be at Consol Energy Center for Game 5 of the best-of-7 series Thursday (8 p.m. ET; NBC, CBC, TVA Sports).
