Datsyuk scored off a rebound with 1:24 left and Zetterberg's goal started a comeback in Detroit's 3-2 victory over the San Jose Sharks on Saturday that evened the Western Conference semifinal at a game apiece.
"Zetterberg and Datsyuk won us the game," said Daniel Cleary, who scored the tying, short-handed goal.
Early on, the Sharks were dominant and looked as if they were headed to a 2-0 lead in the series.
Joe Thornton had a goal and an assist in the first 4:17, and San Jose held onto the two-goal lead until Zetterberg scored late in the first period. It took Detroit nearly 13 minutes to get a shot.
The Sharks made a rare mistake early in the third period with a Detroit-like giveaway. Cleary made them pay for it with the short-handed goal that made 2-all.
San Jose had two power plays midway through the final period, but took only one shot on the first opportunity and three on the second.
Detroit's Dominik Hasek made 17 saves, and Evgeni Nabokov stopped 19 shots.
"We had opportunities throughout the game and Hasek made some great saves," San Jose coach Ron Wilson said. "But I think about the dumb mistakes we made in the third period that you can't make in a playoff game."
Game 3 is Monday night in San Jose.
"Suddenly, we're in a best-of-five series going back to their building," Red Wings coach Mike Babcock said. "I think you're going see us really play, and be even tougher to play against."
Joe Louis Arena was quiet when the Sharks jumped ahead early again, but the fans got revved up as Detroit rallied unlike the series opener when it lost 2-0.
The crowd collectively screamed and jumped to its feet when Datsyuk scored.
Zetterberg carried the puck behind the net and got it to Mikael Samuelsson, whose shot from the left circle deflected toward a swooping Datsyuk in front of crease and he beat the sprawled Nabokov.
"We didn't do one thing right in the whole shift," Wilson said. "At the end of the game, you're making sure you don't get scored against in the last minute."
EAST RUTHERFORD, N.J. - Jamie Langenbrunner scored on a breakaway 1:55 into the second overtime to lift New Jersey over Ottawa, giving the Devils a home split of the first two games in the Eastern Conference semifinal series.
Langenbrunner picked up a loose puck in the neutral zone, fought off a hook from trailing defenseman Joe Corvo and shoved the puck past sprawled goalie Ray Emery.
New Jersey seemed set to win it in regulation, after first-period goals by Brian Gionta and Sergei Brylin, but Dany Heatley tied it for the Senators with 26.4 seconds left in the third.
