Pittsburgh Penguins' Evan Rodrigues (9) celebrates his hat trick with Bryan Rust during the third period of an NHL hockey game against the San Jose Sharks in Pittsburgh, Sunday, Jan. 2, 2022. Rust also had a hat trick in the game, and the Penguins won 8-5.

PITTSBURGH — The Pittsburgh Penguins enjoyed a strong six-goal start after a lengthy layoff.

A third-period lull allowed the San Jose Sharks back into the game, but Evan Rodrigues and Bryan Rust came through when Pittsburgh needed it most.

Rodrigues and Rust both finished off hat tricks in the third period and the Penguins beat the Sharks 8-5 Sunday for their eighth straight win — and first since Dec. 19.

“I loved the start we had,” Penguins coach Mike Sullivan said. “We brought a ton of energy at the start of the game. We were rewarded, but as a result, when you get up by that many goals, you’re fighting against human nature to stay diligent.”

Rodrigues and Rust each scored twice as the Pens built a 6-1 lead in the first period. Both added insurance goals in the final period, with Rodrigues completing his first career hat trick with 2:01 left and Rust scoring into an empty net with 11 seconds remaining. Rust had a career-best five points.

The last time two Penguins’ players scored hat tricks in one game came on Dec. 11, 2008, when Petr Sykora and Pascal Dupuis did it.

“I was shocked that there were any hats left,” Rust said.

San Jose scored three times in the first 4:09 of the third period but couldn’t overcome the huge deficit, which led to an early exit for goalie James Reimer. Alexander Barbanov, Brent Burns, Matt Nieto, Jacob Middleton and Logan Couture scored for the Sharks.

“If you would’ve told me that it would be a one-goal game with 2 1/2, 3 minutes left in the third, I don’t think anyone would believe you,” Sharks defenseman Erik Karlsson said.

Casey DeSmith made 22 saves for Pittsburgh in place of starter Tristan Jarry, who is one of four Penguins in COVID-19 protocols. Pittsbugh hadn’t played since Dec. 19.

Kasper Bjorkqvist scored his first NHL goal and Jake Guentzel his 16th of the season for the Penguins, who have won eight or more games consecutively for the 11th time in franchise history. It’s the first time Pittsburgh has won eight straight since 2018-19.

Rodrigues has a career-best 13 goals this season and has five goals and seven points in his past four games. He scored twice in the first 4:11.

The Sharks had won two straight, including a wild 8-7 win over Arizona on Dec. 28. They’ve lost four of seven overall.

Reimer allowed six goals on 17 first-period shots. Zach Sawchenko replaced Reimer in the second period and made 20 saves in his NHL debut.
