The Islanders got to Devils goalkeeper Martin Brodeur for four goals on just eight shots over the first 20 minutes.
Anders Lee got the Islanders going with a power-play goal just 3:32 into the game. Bailey then made a steal at the top of the circle, skated in alone and fired it past the 41-year-old Brodeur for a 2-0 lead.
Rostislav Olesz got the Devils on the board before Bailey struck again, firing a backhander past Brodeur with 1:55 left in the period.
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.
