With two goals on the night, Henrique is now three away from 100 as a Duck.
The Sharks would respond in the blink of an eye though, tying the game and then taking the lead on a pair of blueline bids by Karlsson.
The first came as he walked the stripe from right to left, looking for a lane before getting his shot through a swarm of bodies in front of Stolarz. The second, scored 23 seconds later, was tipped on the way, deflecting off the skate of Simon Benoit and changing direction.
Karlsson, who is second among active NHL defensemen in career points (162-512=674), goals and assists, has eight points (6-2=8) in his last three games.
Vatrano continued the back-and-forth affair four minutes later, tying the game on a one-timer from the slot. As Isac Lundestrom circled the net, Vatrano snuck towards open ice between the hashmarks, catching a Sharks forward puck-watching and wasting no time with his shot, beating Kahkonen inside the near post.
