The Bruins today claimed forward Kaspars Daugavins off waivers from the Ottawa Senators. According to a team release, he will join the B's when his U.S. work visa has been secured. Daugavins, you may recall, attempted that exotic spin-o-rama move against the Bruins in the shootout in Ottawa on March 11 that Tuukka Rask stopped in the Boston win. The Bruins may be looking for some shootout magic, but more likely they are in search of depth in the event they make some deals — say, Jordan Caron, perhaps — before the April 3 trade deadline. The 24-year-old Daugavins, who has 1-2-3 totals and is minus-7 in 19 games, comes with a salary of $635,000 this season and is scheduled to become a restricted free agent in the summer. Caron is one of the B's better trade commodities, along with Matt Bartkowski and perhaps Torey Krug. GM Peter Chiarelli declared on the radio this morning that he was not trading goalie prospect Malcolm Subban.
