Teemu Selanne snapped out of his scoring slump with a goal and two assists last night and host Anaheim beat Detroit, 5-3, to even the series.
The Ducks tied the Western Conference finals 2-2, with the best-of-seven series shifting to Detroit for Game 5 on Sunday.
The Ducks built a 3-1 lead in the opening period, lost it in the second, then Ryan Getzlaf scored on a power play with 14 minutes, 36 seconds remaining to put them ahead to stay. Jean-Sebastien Giguere made that lead hold up, finishing with 36 saves.
Corey Perry, Ric Jackman and Selanne had first-period goals as the Ducks scored three times on their first eight shots against Dominik Hasek, who faced 22 shots.
Rob Niedermayer capped the scoring with an empty-net goal with 1:08 remaining.
Daniel Cleary had two goals and an assist against the Ducks, who won despite the absence of defenseman Chris Pronger, serving a one-game suspension for a blow to the head of Tomas Holmstrom in Game 3.
Jackman helped fill in for Pronger and scored on his first shot of his initial appearance in a playoff game, making it 2-1 in the opening period.
Selanne's goal was his first in five games and followed his assist on Jackman's goal, Selanne's first assist in four games.
Getzlaf beat Hasek with a 40-foot wrist shot. Anaheim's Todd Marchant screened the goalie on the play, which came with Cleary off for tripping Ducks defenseman Kent Huskins.
Anaheim had gone 0-for-16 on the power play during the first three games of the series and 0-for-31 over the previous five games combined. The Ducks finished the game 2-for-5 with a man advantage.
