Game 2 of the best-of-seven Western Conference matchup is Friday night in Anaheim. Penner poked the puck in after Minnesota defenceman Kim Johnsson crashed into Wild goalie Niklas Backstrom, sending him sprawling backward into the net.
The puck was sitting in the crease, and Corey Perry swept it toward the goal. Penner took a couple of swipes at it and forced it in.
Teemu Selanne tied it for Anaheim with a second-period goal, just 3:51 after Pavol Demitra scored for Minnesota.
Ilya Bryzgalov started in place of Jean-Sebastien Giguere and made 24 saves for Anaheim. Backstrom stopped 32 Ducks shots.
Giguere has been taking time off to be with his wife and newborn son. Maxime was born April 4 with a condition that could leave him blind in his right eye. Giguere and his wife, Kristen, were worried about the vision in the baby's left eye as well, but a specialist told them on Tuesday that their son will have sight in that one.
Giguere, who was on the bench and available to play Wednesday, was the MVP of the 2003 Stanley Cup playoffs, when the Ducks were beaten in Game 7 of the Stanley Cup finals by New Jersey.
Bryzgalov played well during the post-season last year when Giguere was injured, helping Anaheim advance to the Western Conference finals. The Ducks lost then to Edmonton.
