Celebrini slowly skated in from the point and roofed a wrist shot over Vitek Vanecek’s blocker. It was his second hat trick of the season and third in the NHL.
Will Smith had two assists for the Sharks (9-8-3), who had lost two in a row. Yaroslav Askarov made 24 saves.
JJ Peterka scored twice in the third period for the Mammoth (10-7-3), who were coming off a 3-2 overtime loss at the Anaheim Ducks on Monday and are 1-3-3 in their past seven games. Vanecek made 19 saves.
Celebrini gave the Sharks a 1-0 lead at 1:47 of the first period. Philipp Kurashev passed out front to Smith, who then sent a cross-slot feed to Celebrini for a shot into an open net from the bottom of the left circle.
Celebrini made it 2-0 at 5:58. He took a lead pass from Collin Graf and scored five-hole with a wrist shot on a breakaway.
Peterka cut it to 2-1 at 9:25 of the third period. He received a stretch pass from Lawson Crouse, skated down the right wing, and beat Askarov glove side on his own breakaway.
John Marino thought he tied it 2-2 at 13:38, but the referees called the goal off for goaltender interference. Utah coach Andre Tourigny challenged the ruling, but the call stood after a video review.
However, Peterka did tie the game 2-2 at 17:09. He weaved his way into the offensive zone before scoring with a wrist shot from the right circle that trickled under Askarov’s blocker.
