DETROIT - Todd Marchant scored 1:15 into the third overtime on Sunday to lift the Anaheim Ducks to a 4-3 win over the Detroit Red Wings and even their Western Conference semifinal series 1-1.
Jonas Hiller made a career-high 59 saves, while Ryan Getzlaf, Chris Pronger and Ryan Carter also scored for the Ducks.
Anaheim will host Game 3 on Tuesday.
Brad Stuart, Mikael Samuelsson and Johan Franzen scored for the defending Stanley Cup champion Red Wings, who lost for the first time this post-season.
Detroit goalie Chris Osgood stopped 42 shots in defeat.
In the series opener, Detroit's Nicklas Lidstrom scored late in the third to avoid overtime.
On the winner Sunday, Marchant carried the puck up the middle of ice, made a move to slip into open space in the left circle and flicked a wrist shot past Osgood.
The Red Wings did not take advantage of a rare power play in overtime when Scott Niedermayer was called for tripping 11:08 into the first extra period.
Detroit also didn't have anything to show for outshooting Anaheim 14-6 in the first overtime and 15-9 in the second.
The game marked the post-season encounter to go beyond one overtime in these playoffs. It was also the longest playoff game since the Pittsburgh Penguins beat Detroit midway through a third overtime in Game 5 of the Stanley Cup finals last year.
The Ducks have won five straight overtime playoff games against Detroit, winning twice after regulation in the 2007 Western Conference finals enroute to hoisting the Stanley Cup.
The second-seeded Red Wings have been pushed physically and prodded mentally by the eighth-seeded Ducks after not trailing once in the first round against the Columbus Blue Jackets.
Anaheim dominated the top-seeded San Jose Sharks in the first round to set up a matchup between the Ducks and Red Wings.
Detroit scored first as Stuart was credited for a goal - following a lengthy video review - after he centred the puck off his skate and it was redirected into the net by Anaheim's James Wisniewski.
Getzlaf, who began the day tied for the NHL lead in playoff scoring, scored and had an assist on Pronger's go-ahead goal 34 seconds apart midway through the first period.
Samuelsson made it 2-2 late in the first period as the teams combined for as many goals as they had in 59-plus minutes Friday night.
Carter put Anaheim ahead-for the second time in the game and the third time in the series - early in the second period. The Ducks held onto the lead for 20-plus minutes until Franzen scored his fourth goal of the playoffs 5:19 into the third period.

The defending champion and previous Cup winner are meeting in the playoffs for just the third time since the NHL expanded in 1967. In 1991, Edmonton played Calgary. In 1971, Montreal faced Boston.
