PITTSBURGH — The Pittsburgh Penguins and defenseman Ian Cole have agreed to a new contract.

The three-year deal, announced on Monday, has an average value of $2.1 million per season and will keep Cole with the Penguins through the 2017-18 season.

Pittsburgh acquired the 26-year-old Cole from St. Louis in March in exchange for defenseman Robert Bortuzzo.

Cole had one goal and seven assists in 20 games with the Penguins while averaging 18:28 of ice time. He posted career highs in goals (five), assists (12) and penalty minutes (51) in 74 combined games with Pittsburgh at St. Louis.

Cole was set to become a restricted free agent. The Penguins will likely be searching for depth at defenseman with veterans Paul Martin and Christian Ehrhoff expected to head elsewhere when free agency begins Wednesday.
