Maroon, who grew up in Oakville and once played for the St. Louis Bandits of the North American Hockey League, has played in seven NHL seasons, including stints with the Anaheim Ducks, Edmonton Oilers and New Jersey Devils.

"We're excited to add Pat Maroon to our group," Blues General Manager Doug Armstrong told stlouisblues.com. "Things picked up over the last few days, and last night about 10:30 p.m. I got a call from him and his representative saying they'd like to be part of the St. Louis Blues."

Maroon set a career high in games played (81) and goals (27) just two seasons ago with the Oilers, and last season set a career high in points (43) while splitting time with Edmonton and New Jersey.

Overall, Maroon has recorded 178 points (78 goals, 100 assists) and 451 penalty minutes in 375 career regular season games in the NHL.

"This is a one-year opportunity for him to come back, hopefully play with some really good centermen and get back to that 27-goal performance he had in Edmonton, or close to it," Armstrong said. "We think he can help our team. I talked to some of our players about him, competing against him, and they spoke very highly about how hard he was to play against, how difficult he was to move in those high traffic areas. It's just another player we add to our group that makes us a little better than we were yesterday."

The signing, the latest in a busy summer for Armstrong, comes after the additions of free agents Tyler Bozak, David Perron and Chad Johnson. Armstrong also acquired Ryan O'Reilly from the Buffalo Sabres via trade.
