The Bruins added another prospect into the Chestnut Hill-to-Causeway Street pipeline with the 51st pick in the NHL draft on Saturday.

In the second round, the B’s selected William Moore, a 6-2, 175-pound center who played for the US National Team Development program. Born in Mississauga, Ontario, he is a dual citizen of the Canada and the US and will be headed to Boston College, though he could have a stop in junior hockey for a year before that.

He joins James Hagens, selected in the first round on Friday, Oskar Jellvik, Andre Gasseau and Kristian Kostadinski as current or future Eagles in the B’s prospect pool.

Moore posted 27-32-59 totals in 54 games.

With their second pick in the second round (61st), the B’s chose Swedish defenseman Liam Pettersson. At 6-2, 170 pounds, Pettersson clearly needs to fill out a bit and, as a left shot, he doesn’t address an organizational need at right D. While not expected to be high-end prospect, his strength is in his transition game. He had 6-15-21 totals for the Vaxjo Lakers junior.

The B’s then moved their third round pick (69th) to Montreal for the 79th and 108th picks.
