Miller preserved the lead with a save on Seth Jones with Columbus shorthanded at 8:55 of the third period. Nick Foligno led the rush and passed in front to Jones before the defenseman tried to put a backhand past Miller, who poke-checked the puck.
"There's not many situations that you can throw at him that he hasn't been through," Ducks coach Dallas Eakins said of the Miller, a 39-year-old who is in his 17th NHL season. "He's calm back there. He's almost like a second coach back there sometimes."
Jones hit the post with 5:19 left in the third off a face-off win. It was the second time Miller got help. A shot from the right face-off circle by Oliver Bjorkstrand during a Columbus power play went off the crossbar at 28 seconds of the second period.
Silfverberg scored shorthanded at 12:59 of the second for a 1-0 lead. Korpisalo made a save on Rakell's shot from the left side on a 2-on-1, but Silfverberg scored on the rebound.
Fowler made it 2-0 at 14:56, scoring inside the far post after a drop pass in the right face-off circle from Ondrej Kase.
"I just think the tale of the game is really that we got impatient there for three or four minutes and that's what cost us two goals," said Foligno, the Blue Jackets captain. "After a tough bounce on the power play, you can't lose yourself in the next few minutes and we did, and they get that next one.
"Now you're playing from behind by two. We got the really nice goal by [Dubois] to kind get us back in the game, but we just couldn't get the bounce to go our way. That should be a lesson to us."
Dubois made it 2-1 with 3:44 left in the second when his shot from a sharp angle on the left side bounced off Miller's right shoulder and into the net.
The Ducks have given up one goal in four of their five games and have the best goals-against average in the NHL (1.20). They lost 2-1 at the Pittsburgh Penguins on Thursday with John Gibson in goal.
"He played great, kept us in the hockey game," Fowler said of Miller. "That's what you expect out of a guy like him who's been around a long time. He prepares himself, works hard, does the little extra things in practice to make sure he's prepared for the game, and I was happy to see his hard work pay off."
