HOCKEY

NHL: The Washington Capitals traded veteran defenseman Brooks Orpik and backup goaltender Philipp Grubauer to the Colorado Avalanche for the 47th pick in the NHL draft, a move that clears salary-cap space for the Stanley Cup champions to re-sign key pending free agents.

Bowness, 63, spent the past five seasons as a Tampa Bay assistant. He has been a head coach for the Jets, Bruins, Senators, Islanders and Coyotes, and coached the Maine Mariners for two seasons.

Dallas also signed defenseman Stephen Johns to a $7 million, three-year extension.
