Miller's win was his 384th in the NHL, one behind Mike Vernon for 15th in League history.
"I'm feeling it right now," Miller said. "I'm tired, but I felt good to get in there and see some pucks. I felt like I was playing the game that I've been trying to strive for for a little while, so that was rewarding to feel that way."

Max Jones, Derek Grant, and Jacob Larsson scored for Anaheim (21-26-5), which was coming off a 4-3 loss to the Tampa Bay Lightning on Friday but is 4-2-0 in its past six games.
Tyler Toffoli scored, and Jonathan Quick made 25 saves for Los Angeles (19-29-5), which has lost six of its past seven games (1-5-1). Drew Doughty missed his third straight game because of an undisclosed injury.
"They got goals from third and fourth-line players, and good for them, they played very well," Kings coach Todd McLellan said. "Deep into their back end, they got a goal from that group, and we didn't get that, and that's the difference at the end of the night. We had a push, but too little, too late."
Jones gave the Ducks a 1-0 lead at 5:43 of the first period. He received a pass by Sam Steel from behind the net and scored with a backhand at the edge of the crease after the Kings failed twice to the clear the puck out of their zone.
