One game after getting shut out on the man advantage, the Sharks struck twice following St. Louis penalties in a 4-0 win Tuesday night that tied the series at one game apiece heading into Game 3 on Thursday in San Jose.

The Sharks lead the NHL with 15 power-play goals this postseason and their 30 percent success rate is tops among all teams that have played more than one round. San Jose is 13-for-32 on the power play in nine playoff wins, compared to 2-for-18 in its five losses.

The Blues managed to neutralize the Sharks in Game 1 when they killed all three power plays in a 2-1 victory. They were short-handed five times in Game 2, including a slash behind the play by Troy Brouwer that led to the Sharks' second goal of the game and an interference call on Steve Ott for hitting Pavelski from behind when the puck was not in the area.

The other big difference in Game 2 was that the Blues failed to take advantage of their power-play chances. After getting a man-advantage goal from captain David Backes to open the scoring in Game 1, St. Louis went 0-for-6 on the power play Tuesday night, including a weak four-minute chance early in the third period when Marleau was called for a high-sticking penalty and the Sharks lead was only 2-0.

The Blues managed 12 shots on the power play but were unable to beat Martin Jones as the Sharks did a good job controlling rebounds and keeping St. Louis to the outside.

Ken Hitchcock said he plans to tinker with his lineup for Game 3 but gave no specifics.

DeBoer said Thornton looked fine Wednesday after taking a slash on his left hand from Jay Bouwmeester during the game.

>>Penguins Double Up Lightning, Take 2-1 Series Lead

Sidney Crosby, Phil Kessel and Chris Kunitz scored third-period goals, helping the Penguins beat the Tampa Bay Lightning 4-2 in Game 3 of the Eastern Conference finals Wednesday night.

Carl Hagelin snapped a scoreless tie late in the second period and Matt Murray had 26 saves for the Penguins, who took a 2-1 lead in the best-of-seven series and proving that they're far from a one-man show.

Crosby's power-play goal off a pass from Evgeni Malkin restored a two-goal lead midway through the final period. Kunitz also beat goalie Andrei Vasilevskiy from the right circle to make it 4-1.

Tyler Johnson and Ondrej Palat scored for the Lightning. They have lost two straight after winning the series opener in Pittsburgh. The defending Eastern Conference champions were outshot 48-28, including 38-16 over the last two periods.

Game 4 is Friday night at Amalie Arena.
