Celebrini gave the Sharks the opportunity to tie it when he dove and poke-checked the puck away from Robert Thomas, denying him a chance at the empty net with 2:22 remaining in the third.
Neighbours scored on St. Louis' third attempt in the shootout, putting the puck onto his backhand and then forehand before shooting past Askarov’s glove. Binnington made a save on William Eklund to end it.
"I try not to think about it too much, just try to watch the guys before me and kind of see what [Askarov's] stance is like," Neighbours said. "[Assistant coach David Alexander's] obviously radioing down from the top and giving us some tips. We looked at a little video quick before the shootout, but at the end of the day, every player's kind of got a couple go-tos and that was one of mine."
Walker put St. Louis up 1-0 just 11 seconds into the first period when he converted in front off a pass from Radek Faksa, who intercepted Askarov's rim around the boards.
"I think if you can just have a good shift in itself, let alone get a goal on the first shift, it kind of sets the tone for the game," Walker said. "'Faks' made a great heads-up play for me there."
