Blackwood made 15 saves in the second, denying Justin Dowling from the slot when his shot hit Blackwood’s right pad and went off the left post at 10:56.
"I just try and put myself in good positions and be able to have a chance to make saves," Blackwood said. "I'm not going to lie, this win is up there, it's up there. There was just a lot of friendly banter (on the ice). I love so many of those guys I played with. I think they have a tremendous group in that locker room ... but that was fun for me."
The Sharks appeared to take a 2-0 lead at 12:45 of the second when Fabian Zetterlund pushed a puck over the goal line at the right post. After a brief discussion by the officials, it was determined Zetterlund interfered with Allen by pushing his pad into the net.
"They got big expectations this year, and it's tough to shut down that cycle game, that skill game, that they have for 60 minutes ... it's almost impossible to do," Sturm said. "I thought we did a great job for the most part, staying tight. Obviously, 'Blackie' had a huge game."
Blackwood made 19 saves in the third period, including seven during a Devils power play after Mario Ferraro took a hooking penalty with 3:32 remaining. Blackwood's 44 saves were the second most by a Sharks goalie in a shutout behind Troy Grosenick (45 saves on Nov. 16, 2014).
"As you get older, you just learn to stay loose and relax and not let the highs or lows get in your face," the 27-year-old goalie said. "The thing is I'm getting older and I'm doing a better job with just being even keel throughout the whole thing."
NOTES: Blackwood became the fourth former Devils/Colorado Rockies/Kansas City Scouts goalie to have a shutout against the franchise, joining Scott Wedgewood (Dec. 2, 2017), Kirk McLean (Oct. 19, 1988) and Denis Herron (March 9, 1977). ... The Sharks are 2-1-1 in four games with forward Macklin Celebrini in the lineup and are 3-8-1 in 12 games without him. Celebrini was the No. 1 pick in the 2024 NHL Draft.
