San Jose struck three times with the man advantage in a 5-3 win over Washington.
Joe Pavelski and Patrick Marleau combined to score those three goals, giving them at least one power play in eight of their last 10 games, including three goals twice and two goals once. The Sharks' 21 percent success rate is fourth-best in the NHL.
"Their power play's good," Matt Hendricks said. "They have a lot of weapons out there. They weren't so much your typical power-play goals, but they got pucks to the net and found ways to get them in. We, penalty killers need to be better. The onus is on us to help our goalie out. We left him out to dry a couple of times."
Meanwhile, the Caps' penalty kill has been abysmal as of late, clocking in at 4-of-9 in their last two home games (44.4 percent). They also failed to convert on four power play chances of their own.
"Work on our special teams the next two or three days of practice, the penalty kill and power play too," head coach Dale Hunter said when asked what his team needs to address. "We got to get more goals off our power play to counter what they do on the PK [penalty kill]."
