The Kings started off hot, scoring three goals within 6 minutes in the 1st period to take a 3-0 lead. Dustin Brown scored twice for L.A., once on a power play in the 11th minute and another in a power play in the 12th minute. Trevor Lewis chipped in with a backhand from 8-feet out during a power play in the 15th minute.
In the 2nd period, Jeff Carter scored in the 1st period to give the Kings a 4-0 advantage.
After jumping to a 3-0 series lead, the Kings hoped to close out the Devils, who claimed one in L.A. and another in Newark.
The Game 5 loss Saturday snapped the Kings' streak of 10 straight playoff road victories.
In Game 4, defenseman Drew Doughty said that the team let playing at home distract them a bit, being so close to clinching the Cup that they didn't play to their potential. But on Monday, they said they weren't thinking about anything beyond just playing well enough to win L.A. its first Cup.
The Kings looked to avoid becoming just the second team in NHL history to blow a 3-0 series lead.
The first and last time the Kings were in the Stanley Cup Finals was in the 1992-93 season. They Kings defeated the Montreal Canadiens in Game 1, but lost the next four games.
