SAN JOSE, Calif. (AP) The Pittsburgh Penguins scored a power-play goal less than three minutes into the second period, opening a two-goal lead. The San Jose Sharks didn't even take their first shot of the period until a little over seven minutes later.

The Sharks' failure to get the puck on the net has them on the brink of elimination from their first-ever appearance in the Stanley Cup Final.

The Penguins regained control of the series with Monday night's 3-1 victory in San Jose, taking a three games to one lead heading into Game 5 in Pittsburgh on Thursday night.

The Sharks outshot and outblocked the Penguins in this one, but were stymied on two power plays while allowing the Penguins to convert on one out of two.

A hyperactive Penguins defensive effort continued to slow down Joe Pavelski, still the playoff leader with 13 goals, and make things difficult for Logan Couture, Joe Thornton and Brent Burns.

Pavelski did send five pucks at the net, one more than his total from the first three games combined.

That San Jose foursome tops the playoff points leaders, all with more than 20 points, with a combined six this series. None of them has found the back of the net against Penguins goalie Matt Murray, who turned away 12 shots in the first two periods and 23 total.

The Sharks' power-play ranked third in the NHL during the regular season, and they have 18 man-advantage goals in the playoffs. The Penguins, fifth during the regular season in penalty kill percentage, have shown again and again that a good defense beats a good offense.

Pavelski and Patrick Marleau had a combined 23 power-play goals during the regular season, but have been unable to create many scoring chances on the rare times they've had a man advantage.

Tomas Hertl, who missed his second straight game with a lower body injury, has the lone power-play goal of the series.

Melker Karlsson scored midway through the third period, on the 21st shot for the Sharks. It was not nearly enough.
