UNDATED (AP) — The No. 1 seeds in the Stanley Cup playoffs find themselves up two games to one in the conference quarterfinals following Pittsburgh's victory and Chicago's loss.

Chris Kunitz (KOO'-nihts) scored a power-play goal 8:34 into overtime to give the Penguins a 5-4 victory over the New York Islanders. The Pens erased an early 2-0 deficit and blew a 4-2 lead before Kunitz notched his second power-play goal of the afternoon off a feed from Sidney Crosby, who had three assists.

Third-period goals by Kyle Okposo (oh-POH'-soh) and John Tavares allowed the Islanders to force overtime.

Game 4 is Tuesday on Long Island.

Minnesota beat the visiting Blackhawks 3-2 on Jason Zucker's goal at 2:15 of OT. Zach Parise (pah-REE'-say) put the Wild ahead 2-1 early in the third period, and the score stood up until Duncan Keith tallied with 2:46 left in regulation.

Pierre-Marc Bouchard scored the Wild's first goal and also assisted on the game-winner as Minnesota drew within two-games-to-one in the series.

Game 4 is Tuesday at Minnesota.

A goaltending change couldn't prevent Vancouver from falling behind three games to none in its conference quarterfinal series with San Jose.

Joe Pavelski and Logan Couture (koo-CHOOR') each scored twice and combined for seven points as the Sharks dumped the Canucks 5-2 in San Jose. The Sharks led 2-1 until Couture collected two goals and an assist during the first 4:07 of the third period to chase Cory Schneider, who was back in goal after missing the first two games with an undisclosed injury.

Couture finished with two assists and Pavelski ended up with three points for the Sharks.

The Sharks can sweep at home on Tuesday.

Ottawa has a 2-1 series lead after Jean-Gabriel Pageau (pah-ZHOH') and Craig Anderson led them to a 6-1 win over Montreal. Pageau scored his first three postseason goals to back Anderson, who stopped 33 shots and played his best while the score was close.

The game featured a brawl that led to eight game misconducts with 12:56 remaining, four seconds after Kyle Turris made it 4-1. Jakob Silfverberg (SIHL'-vur-burg) scored just four seconds after the scrums to turn the game into a rout.

The teams combined for 232 penalty minutes and nine game misconducts.

Game 4 is Tuesday at Ottawa.
