Alex Chiasson, who spent the 2016-17 season with the Calgary Flames and won the Stanley Cup with the Washington Capitals the following year, officially announced his retirement from the NHL on Monday.

Chiasson, 34, appeared in 651 regular season and 37 playoff games during his 11-year NHL career with the Dallas Stars, Ottawa Senators, Flames, Capitals, Edmonton Oilers, Vancouver Canucks, and Detroit Red Wings. The Stars originally selected Chiasson in the second round (No. 38 overall) of the 2009 NHL Draft.

The Flames acquired Chiasson from the Senators in the 2016 off-season, sending defence prospect Pat Sieloff the other way in the deal. Sieloff only appeared in two NHL games (but scored two goals) during his career, but Chiasson skated in 81 games with the Flames in 2016-17, collecting 12 goals and 24 points. He was held off the scoresheet entirely in four playoff contests with Calgary against the Anaheim Ducks.

Chiasson finished 11th in goals and 13th in points in his first season with the Flames. Despite this, the Flames opted against tendering Chiasson a qualifying offer in 2017, making him an unrestricted free agent.

Upon the conclusion of his tenure with the Flames, Chiasson signed his first of many professional try-out deals with the Capitals. He parlayed a successful stint with the team in training camp into a one-year deal, ultimately appearing in 61 games with the Capitals in the 2017-18 season. Chiasson also dressed for 16 playoff games with the Capitals that spring en route to the franchise’s first-ever Stanley Cup championship.

Chiasson spent the following three seasons with the Edmonton Oilers (after initially signing another PTO with the team), reaching the greatest offensive heights of his career — including a 22-goal year in 2018-19 — while spending significant time on the team’s top power-play unit with Connor McDavid and Leon Draisaitl. He subsequently signed four more PTOs in his career, earning deals with the Canucks and Red Wings and being cut by the Arizona Coyotes and Boston Bruins.

Before playing in the NHL, Chiasson spent three seasons at Boston University, topping out with 15 goals and 46 points in 38 games as a junior (and alternate captain) in 2011-12. Just over a year after he turned pro, the Stars included Chiasson in the blockbuster Jason Spezza trade with the Senators.

Chiasson played for four Canadian teams during his NHL career, putting him just two shy of record-holder Michel Petit, who skated for six: the Flames, Oilers, Canucks, Montreal Canadiens, Toronto Maple Leafs, and Quebec Nordiques.
