The Pittsburgh Penguins have signed defenceman John Marino to a six-year contract extension worth $26.4 million, it was announced Sunday.

The deal, which begins in the 2021-2022 season, carries a cap hit of $4.4 million. He has one year remaining on his entry-level deal.

"We are very fortunate to have a young, skilled defenseman like John in our organization," said general manager and executive vice president Jim Rutherford in a news release. "His rookie season proved he is a top-four defenseman with great hockey sense. We were impressed with his strong defensive play and look forward to watching him develop offensively."

TSN Hockey Insider Pierre LeBrun reports Marino's salary breakdown as the following:

Year 1: $1.75 million

Year 2: $3.5 million

Year 3: $5.25 million

Year 4: $6.15 million

Year 5: $5.3 million

Year 6: $4.45 million

Marino, 23, has just one NHL season under his belt but impressed over the course of 56 games last year. He tallied six goals and added 20 assists for a total of 26 points and was plus-17 in 20:15 of average ice time per game.

Marino also finished eighth in Calder Trophy voting.

A native of Easton, Mass., Marino was selected by the Edmonton Oilers in the sixth round (No. 154 overall) in the 2015 NHL Draft. He was traded to Pittsburgh in July of 2019 in exchange for a sixth-round pick in 2021.
