Drew O'Connor scored on a short-handed 2-on-1 wrist shot at 10:43 to make it 4-3, but Celebrini scored No. 20 on a one-timer from Chernyshov at 16:20 to restore the two-goal lead at 5-3.
Most of the team flew in from San Jose in the morning, but Celebrini had a short commute to the rink he used to skate at as a kid with his brother Aiden, who is now a Vancouver defenseman prospect, because their dad, Dr. Rick Celebrini, used to work for the Canucks.
“I had a lot of family here and obviously spent some time at home spending Christmas up here, so it was awesome to kind of get one in front of them,” Celebrini said.
Chernyshov has five points in five games, playing mostly with Celebrini.
“Big man that can really protect pucks, really got a knack for the dangerous areas of the ice, and that's why he's had some success up there,” coach Ryan Warsofsky said. “His frame, you can see it there, he holds on to a puck, finds Mac in the slot. He's going to be a special one.”
Graf scored into an empty net, his fifth goal in four games, at 16:55 for the 6-3 final as the Sharks finished with a goal from six different players, something Reaves said is important.
“You need that to be a playoff team,” Reaves said. “You can't rely on one superstar. It just doesn't work like that. We need that depth scoring. We got to take some pressure off [Celebrini].”
Celebrini wasn’t the only Sharks player enjoying a homecoming in Vancouver.
Defenseman Vincent Iorio is from the Vancouver suburb of Coquitlam and heard his name called after recording an assist on Reaves' goal in the building he once skated in as a kid during the intermission games.
“That was the coolest thing ever so for me to be back here, but this time playing in front of everyone, is pretty cool,” said Iorio, who had at least 30 family and friends at the game. “I was telling my parents just how surreal it is … it's just a full-circle moment.”
NOTES: Celebrini has seven points (two goals, five assists) in five career games against the Canucks. He also became the fastest (38 games) teenager to score 20 goals in a season since Auston Matthews of the Toronto Maple Leafs scored 20 in 36 games in 2016-17. … It was Demko’s first loss in 14 starts against San Jose. … Vancouver center Elias Pettersson returned after missing eight games with an upper-body injury to play his 500th NHL game and finished minus-3 with three shots in 20:47.
