Like his father, Thomas, who played for the Winnipeg Jets from 1981-95, Steen began his NHL career with a Canadian team when he debuted for the Toronto Maple Leafs on Oct. 5, 2005, against the Ottawa Senators. When Steen had a goal against the Montreal Canadiens in his second NHL game three days later, he and his dad became the first Sweden-born father-son combination to score in the NHL.
The Maple Leafs selected Steen in the first round (No. 24) in the 2002 NHL Draft. He represented Sweden at the 2002 World Under-18 Championship and at the World Junior Championship in 2003 and 2004. Steen scored 18 goals as an NHL rookie in 2005-06 and had at least 15 goals in each of his first three seasons.

In 2006-07 he had a League-best rating of plus-23 on the road and played in the YoungStars Game. Steen got his first NHL hat trick, Jan. 4, 2007, against the Boston Bruins, part of a five-point game.
The Maple Leafs traded Steen to the St. Louis Blues on Nov. 24, 2008. He had back-to-back 20-goal seasons for the Blues in 2009-10 and 2010-11. On March 16, 2010, against the Colorado Avalanche, he tied Greg Paslawski's Blues record for the fastest goal from the start of a game (eight seconds).
In 2011-12 he led St. Louis and was 12th in the NHL with a plus-24 rating. In the first round of the 2013 Stanley Cup Playoffs, Steen scored at 13:26 of overtime in Game 1 for the first shorthanded OT goal in Blues playoff history.
Steen was named the NHL First Star of the Month for October 2013 after scoring a league-leading 11 goals. He became the first NHL player to score a goal in each of his team's first 10 wins of the season since Eric Lindros in 1993-94 and finished 2013-14 with 33 goals. Steen had 20 goals in his first 24 games that season, becoming the second-fastest player in franchise history to reach that mark (Brett Hull had 20 goals in 20 games in 1990-91).
