OTTAWA — The Ottawa Senators have signed defenceman Patrick Sieloff to a two-year, two-way contract extension.

The contract will carry an annual value of US$675,000 in the NHL and $125,000 in the American Hockey League in year one, and $725,000 in the NHL and $170,000 in the AHL in year two.

The 24-year-old Sieloff appeared in 58 games with the AHL's Belleville Senators last season, scoring one goal and adding nine assists and 108 penalty minutes while being named the team's defenceman of the year.

He was recalled to Ottawa of the Senators home game on March 20 against Florida, and scored once in his only NHL game of the season that evening. He became the first player in NHL history to score at least one goal in each of his first two games with two separate teams.

A native of Superior, Mich., Sieloff has appeared in 212 career AHL contests with the affiliates of Calgary and Ottawa recording 38 points (seven goals, 29 assists) and 333 penalty minutes.

Originally drafted by the Flames with their second-round pick (42nd overall) at the 2012 NHL Draft, Sieloff was acquired by Ottawa in exchange for forward Alex Chiasson on June 27, 2016. He made his NHL debut with Calgary during the 2015-16 season, recording one goal and two penalty minutes in his first NHL game on April 9, 2016.
