Bruins trade Sobotka

LOS ANGELES -- Boston Bruins general manager Peter Chiarelli just announced the trade of forward Vladimir Sobotka to the St. Louis Blues in exchange for defenseman David Warsofsky, who is playing at Boston University.

Chiarelli said the Bruins have no plans to take Warsofsky out of school, but the organization really likes the way he plays.

Sobotka was a sparkplug for the Bruins and played a total of 134 regular-season games for Boston in the last three seasons, recording six goals and 16 assists for 22 points. The 22-year-old can play both center and wing and posted a minus-16 rating.

"He's a wrecking ball, a real competitive kid," Chiarelli said. "We acquired Greg Campbell [earlier this week] and we've got some other centers coming in. Vlady, on the wing and with his size, it's not that he has difficulty, but he's had trouble adjusting. I talked to Vlady and he's happy that we're giving him a chance somewhere else. He's a good kid and I like the way he plays, and moving to another organization he'll get a better chance."

Warsofsky, 20, is a junior at BU and is a native of Marshfield, Mass. He's played 79 games for the Terriers, posting 15 goals and 31 assists for 46 points and 75 penalty minutes. During the 2009-2010 season, he played 34 games and scored a career-high 12 goals, while tying his career-high with 23 points.

He also played for the United States National Development team in 2007-2008. The 5-foot-9, 170-pounder was originally drafted in the fourth round (95th overall) in the 2008 draft by St. Louis.

The 5-foot-10, 183-pound Sobotka was Boston's fourth-round pick (106th overall) in the 2005 draft.

In related action on Saturday, the Bruins made qualifying offers to restricted free agent defensemen Mark Stuart and Adam McQuaid, along with forward Blake Wheeler.

Forward Daniel Paille has yet to be qualified, but he will be soon, according to Bruins general manager Peter Chiarelli.

Goaltender Kevin Regan was not qualified.
