Kuraly made it 6-4 at 7:39, scoring with a snap shot after a blocked shot came to him in the left circle.
Jenner scored an empty-net, short-handed goal with 33 seconds left for the 7-4 final.
"I thought we played a good first period, second period not so much, and third period back to the way we know we can play," Kuraly said. "I guess it's a lot easier to learn when you end up winning, so hopefully we can take that into account that we can still learn a lesson and win a game."
Columbus scored three goals on its first five shots of the game.
Gaudreau gave the Blue Jackets a 1-0 lead at 3:32 of the first period when his wrist shot hit Gibson's mask and went in off Werenski’s right knee.
"The first period had a weird feeling to it," Ducks coach Greg Cronin said. "I thought we controlled the puck most of it, and then we turn it over and give them an odd-man rush."
Gaudreau ended a 17-game goal drought when he scored off a 2-on-1 to make it 2-0 at 9:32.
