Henrik Zetterberg picked a good time to break out of his scoring slump.

Zetterberg got his second goal 1:04 into overtime, lifting the host Detroit Red Wings to a 4-3 win over the Anaheim Ducks in Game 6 on Friday night to extend their first-round series.

Detroit blew a two-goal lead in the last 3½ minutes of the third period, sending the original six NHL team to a fourth OT in a series for the first time in franchise history.

Emerson Etem and Bobby Ryan scored 51 seconds apart late in regulation to pull the Ducks into a 3-3 tie.

Zetterberg, who scored a go-ahead goal 6:19 into the third period, had a shot to win it with about a minute left. But his shot hit the right post and slid across the crease.

He found the back of the net with a slap shot from above the left circle to end the game and send the series back to California.

"Those two were kind of ugly ones, but that's what you need in the playoffs," Zetterberg said.

Zetterberg's first goal snapped a career-long, seven-game postseason skid -- dating to last year's first-round exit against Nashville -- and was the 52nd of his career in the playoffs. He has an NHL-high 50 goals in the playoffs since 2006.

Kings 2, Blues 1: Dustin Penner scored the tiebreaking goal in the final second of the second period, and host Los Angeles advanced to the second round with a victory in Game 6. Drew Doughty scored his first goal of the postseason for the defending Stanley Cup champions, who won four straight to finish off fourth-seeded St. Louis.

Maple Leafs 2, Bruins 1: Tyler Bozak and Clarke MacArthur scored and James Reimer stopped 43 shots to help Toronto win at Boston to stay alive. The Bruins lead the series 3-2.

Capitals 2, Rangers 1: Mike Ribeiro scored 9:24 into overtime, and host Washington beat New York to regain the momentum -- and the lead -- in their first-round playoff series. The Capitals lead the series 3-2. Game 6 is Sunday in New York.
