Just how rare is the accomplishment? His father, Mike, played 17 years in the NHL, skated in 1,049 games and never scored three goals in a regular-season contest (though he did have one in a 2004 playoff game). Sillinger is now the fifth rookie in Blue Jackets history to notch a hat trick, and the second youngest player in team history to do so, with only Nikita Filatov's 2009 hat trick coming from a younger player.
In fact, since 1991-92, there have been only seven hat tricks scored by 18-year-olds in the entire NHL. Three of those were accomplished by current teammate Patrik Laine during his rookie season of 2016-17 in Winnipeg, another is Filatov's, and the other two belong to Ryan Nugent-Hopkins (2011) and Jordan Staal (2007).
"To get a hat trick at 18 is absolutely ridiculous," linemate Max Domi said. "I did see some stat on the bench -- I can see the screen for the live broadcast (on television) and they were talking about how Patty had three when he was 18. I was like, 'Are you serious? You had three hat tricks at 18?' I was like, 'Silly, you have some work to do, kid.'
"But that's unbelievable. That's special."
Drafted 12th overall in the 2021 draft, Sillinger came in billed as a complete center who could play at both ends of the ice while also boasting a high-level shot that was thought of as one of the best in the draft.
He certainly has lived up to all of that as the season has gone on, but as with just about any player who is the youngest in the league, becoming a consistent player on the offensive end of the ice has taken time.
But it came together Sunday night as Sillinger clearly clicked in an elevated role, as he injury to top center Boone Jenner moved him up into a trio that featured scorers Oliver Bjorkstrand and Max Domi. Sillinger first got on the board when he tied the game at 2 in the first period as Bjorkstrand hustled onto a puck and fed him all alone in front of the net, and Sillinger's second goal in the middle period gave the Jackets a 4-2 lead as he tipped Bjorkstrand's shot past goalie Logan Thompson.
Just 1:50 after that goal, Bjorkstrand sprang his two fellow forwards on a 2-on-1, with Domi saucering a pass across the ice for Sillinger to one-time through Thompson's legs from the right circle.
Sillinger entered the game with just one assist in the previous seven games while averaging 9:52 of ice time in that span. There had been some talk that Sillinger had hit a rookie wall -- his previous high in games played in a season was 48 with Medicine Hat of the WHL 2019-20 -- but that also was viewed as a normal part of the adjustment process to the league.
"As a young guy in the league, there will be a lot of games where you don't as much opportunity as you're used to, but for me I just try to contribute any way I can," Sillinger said. "It was nice to get a couple of bounces (against Vegas) and have a little more offense than usual. I think I had a couple of good looks, even the ones that didn't go in, so it's always nice to get myself in those areas. When you're playing with Bjorky and Domes, they're really good passers, really good playmakers. I thought it was a good night overall."
What has impressed head coach Brad Larsen the most is that even when Sillinger has found it tough to get on the scoreboard, his effort level hasn't waned.
