The Washington Capitals have just signed Walker to a three-year entry-level contract, according to Monumental Network.
In the 2014 NHL Entry Draft, the Capitals took him with the 89th overall pick. To secure Walker's spot, they sent the 104th and 118th picks to the New York Rangers, in exchange for the third round selection.
“We’d rather do what we have to do in order to move up and make sure we get the player we want rather than sit back and hope that player’s still there," assistant GM Ross Mahoney told Ross Prewitt of the Washington Post.
Walker now has a chance to be the first Australian to play a game at the NHL level.
