Nick Leddy was traded to the St. Louis Blues by the Detroit Red Wings on Monday.
Detroit received forward Oskar Sundqvist, defenseman Jake Walman and a second-round pick in the 2023 NHL Draft for the defenseman.
St. Louis also received defender Luc Witkowski.
Leddy is in the final year of a seven-year contract he signed with the New York Islanders on Feb. 24, 2015.
The 31-year-old defenseman has 16 points (one goal, 15 assists) in 55 games this season.
Leddy was acquired by the Red Wings in a trade with the Islanders on July 16, 2021.
“I think Nick brings experience,” Blues general manager Doug Armstrong said. “If you look at the last two years of the playoffs, his team has made the semifinals. … He’s a guy who can register big minutes at important times of the year for teams that play deep. He’s a skater, he’s a puck mover.
Selected by the Minnesota Wild in the first round (16th overall) of the 2009 NHL Draft, Leddy scored 352 points (66 goals, 286 assists) in 831 regular season games for the Red Wings, Islanders and Blackhawks of Chicago and 33 points (seven goals, 26 assists) in 121 Stanley Cup Playoff games.
Leddy won the Stanley Cup with the Blackhawks in 2013.
Witkowksi, a 31-year-old defenseman, had seven points (three goals, four assists) in 44 games with Grand Rapids of the American Hockey League and played one game with the Red Wings this season. He has one season left on a two-year deal he signed with the Red Wings on July 29, 2021 and could become an unrestricted free agent after next season.
Selected by the Tampa Bay Lightning in the sixth round (160th overall) of the 2008 NHL Draft, Witkowski scored 13 points (two goals, 11 assists) in 132 regular season games with the Red Wings and Tampa Bay Lightning and no points in two Stanley Cup Playoff games.
The Blues (34-18-9) are third in the Central Division, one point behind the second-place Minnesota Wild and 16 behind the first-place Colorado Avalanche.
Sundqvist has 15 points (four goals, 11 assists) in 41 games this season. The 27-year-old has 87 points (36 goals, 51 assists) in 270 regular season games with the Blues and Pittsburgh Penguins since being selected by Pittsburgh in the third round (81st overall) of the 2012 draft of the NHL.
He is in the third season of a four-year contract he signed with the Blues on July 21, 2019 and can become an unrestricted free agent after the season.
Sundqvist had 10 points (four goals, six assists) in 36 playoff games and won the Cup with the Blues in 2019.
“Honestly, ‘Sunny’ has been one of my favorite players,” Armstrong said. “He always has a smile. I always liked being with him. A very good player, he will always have good memories here as a Blue. … I think he is going to be a good player for a long time and this organization was better for him to be part of than before he got here.”
Walman has six points (three goals, there are assists) in 32 games this season. The 26-year-old has eight points (four goals, four assists) in 57 regular-season games since being selected by St. Louis in the third round (82nd overall) of the 2014 NHL Draft. He is in the final season of a two-year contract he signed with the Blues on November 19, 2020 and can become a restricted free agent after the season.
The Red Wings (25-30-7) are fifth in the Atlantic Division.
