Pavel Buchnevich was traded to the St. Louis Blues by the New York Rangers for forward Sammy Blais on Friday.
New York also received a second-round pick in the 2022 NHL Draft.
Buchnevich, who can become a restricted free agent July 28, scored an NHL career-high 48 points (20 goals, 28 assists) in 54 games this season.
"I'm excited to have Pavel join our group," Blues general manager Doug Armstrong said. "... He's got good size at 6-3. He is a left shot, can play the right side. He's scored in the League recently. He's 26 years old. A player that obviously we control for a year and would like to sign long term. ... A very good penalty killer too, a very underrated penalty killer. So he's going to touch all aspects of our game and he's at a good age as we continue to retool this roster, and I think he's a good piece for us."
Selected by New York in the third round (No. 75) of the 2013 NHL Draft, Buchnevich has scored 195 points (79 goals, 116 assists) in 301 regular-season games and has one assist in eight Stanley Cup Playoff games.
"I think he's a definite top-six forward," Armstrong said. "You look at the minutes that he averaged last year (18:44), where he finished in scoring on the Rangers (fourth), I think he's just starting to come into his own."
