The Westford Academy boys’ hockey team stunned No. 10 Archbishop Williams, 3-2, in the Cape Cod Holiday Tournament at Falmouth Arena Friday, with Cam MacDonald scoring the winning goal with 11 seconds left in regulation.

Defenseman Jake Mercier found the streaking MacDonald, who was denied on his initial shot but scored on the rebound. The junior left wing also assisted on the first goal for the Grey Ghosts (2-2) and scored the team’s second goal midway through the third period, also off a rebound.
