The Ducks recovered to win a game they almost gave away and even the NHL Western Conference final at two games each. Getzlaf broke a 3-3 tie when he wired a shot from the point that screened Detroit goaltender Dominik Hasek didn't see. It was the second power-play goal of the night for the Ducks. Rob Niedermayer sealed the win with an empty-net goal with 68 seconds remaining.
The Ducks, playing without suspended defenceman Chris Pronger, badly needed the win so they didn't return to Detroit trailing 3-1 in the series. They also needed to regain their confidence after being whipped 5-0 Tuesday.
"Tonight was a gut check for us," said coach Randy Carlyle. "We were a very determined group from the beginning."
Game 5 of the best-of-seven series will be played Sunday at Joe Louis Arena.
Teemu Selanne broke out of a four-game point drought with a goal and two assists while defenceman Ric Jackman scored his first career playoff goal for the Ducks.
Dan Cleary had two goals and an assist while Todd Bertuzzi had a goal and assist for the Red Wings, who battled back from a 3-1 first period deficit to tie the game after 40 minutes.
In a twist, it was Cleary who was in the penalty box when Getzlaf scored his goal.
"I thought we did a lot of good things but I thought we shot ourselves in the foot a little bit," said Detroit coach Mike Babcock.
"They had a couple of seeing-eye pucks tonight."
Corey Perry scored the other Anaheim goal while defenceman Francois Beauchemin had two assists. Goaltender J.S. Giguere had to be sharp as the Wings outshot the Ducks 39-23.
Perry said the Ducks knew they faced a challenge without Pronger in the lineup.
"We had to battle hard," he said. "We knew it wasn't going to be easy. We had to come out and prove to ourselves we can play without him.
"Thank God we've got him back for Game 5."
Cleary tied the game 3-3 at 15:36 of the second on a power play after Niedermayer was sent off for hooking. The sellout crowd of 17,375 didn't like the call and booed loudly.
It took the Wings just 20 seconds to score. Cleary dug the puck out during a scramble in front of the Duck net and lifted a shot over a sprawled Giguere.
Bertuzzi had made it 3-2 on another power play at 7:48. The big forward was parked in front of Giguere when he took a Robert Lang pass from behind the goal and banged at a puck that went off the goaltender and into the net.
It was Bertuzzi's second goal in as many games.
Selanne gave Anaheim a 3-1 lead late in the first period when he pounced on a bouncing puck in front of the Red Wing net and beat Hasek. The flashy Finn celebrated his first point since Game 4 of the conference semifinal against Vancouver.
Jackman, pressed into service because of Pronger's suspension, scored Anaheim's first power-play goal of the series at 11:46 of the first period. He jumped on a loose puck and blasted a shot that beat Hasek.
Pronger, a Norris Trophy candidate, was suspended for one game for his hit Tuesday on Tomas Holmstrom.
Jackman, a 28-year-old journeyman, had never played in a post-season game during an eight-year career in Dallas, Boston, Toronto, Pittsburgh and Florida. Obtained from Florida in January, he hadn't played in this year's playoffs due to back spasms.
A Bertuzzi giveaway resulted in the game's first goal. Bertuzzi floated a pass through the middle of the ice that Perry intercepted at the blue-line then launched a shot that got past Hasek with just 1:37 gone in the game.
The Wings made it 1-1 on a Giguere miscue. He tried to send a puck around the boards that ended up on defenceman Chris Chelios's stick. Chelios let go a shot from the boards that Cleary directed into the net.
The crowd was on its feet cheering and waving towels when the Ducks killed off a two-man advantage early in the third period.
Notes-Anaheim's 5-0 loss on Tuesday was their worst playoff defeat ever. The previous high was a 5-1 loss to Detroit in the first round of the 1999 playoffs. . . . The Ducks were 6-7-3 in the 16 regular season games Pronger was hurt this season. . . . Ducks GM Brian Burke said Detroit did "the honourable thing" when they put Holmstrom back on the ice Tuesday because "there are teams in this league that would have put him in an ambulance and sent him somewhere."
