Smith put San Jose ahead 3-2 at 17:21 of the second when he drove in with Zetterlund on a 2-on-1 and shot past Montembeault’s glove from the left circle.
“It was kind of a bouncing puck so I tried to settle it down,” Smith said. “I just saw an opening and I put it there.”
Alex Newhook tied it 3-3 at 2:22 of the third period with a tap-in near the right post.
“We just can’t break a game open, that’s for sure,” Sharks coach Ryan Warsofsky said.
Owen Beck got the secondary assist for his first point in eight NHL games, including seven this season.
“It took long enough,” the forward said. “You always want to produce no matter the role, the league, the situation. You always want to contribute so it was definitely in the back of my mind, but just awesome to get that one off my back.”
