Beauchemin fired a slap shot past goalie Viktor Fasth to give the Ducks their 50th win of the season (50-18-8). Perry and Ryan Getzlaf assisted on the deciding goal.
With the Ducks trailing 2-0, Perry scored his 40th goal just 37 seconds after Jordan Eberle doubled Edmonton's lead at 2:51. Perry then tied it with 8:35 left. It is the second time Perry has reached 40 goals in a season.
Rookie goalie Frederik Anderson (19-5) stopped 30 shots.
Philip Larsen scored his third of the season in the first period for Edmonton.
This is a big year for us in a lot of ways. You can see Garth and management really trying to find that solution to get us into the playoffs and consistently have that. The pressure is great. You have to enjoy it. It just means there's a great opportunity ahead of you.
