The 18-year-old center is the second No. 1 pick in three years to score in his first preseason game for the Devils. Nico Hischier, selected No. 1 in the 2017 NHL Draft, scored in his preseason debut, a 4-1 win against the Washington Capitals on Sept. 18, 2017.
Hughes played 16:04, had three shots on goal, and was 4-for-16 on face-offs.
"I have to start winning some [face-offs], and another thing I need to improve is my movement on the power play," Hughes said.
Hughes skated on a line with Gusev, who was acquired in a trade from the Vegas Golden Knights on July 29 before signing a two-year contract the same day. Gusev played 17:34.
Hughes exhibited great vision and speed 6:20 into the third period when he skated behind the Boston net before sending a pinpoint backhand pass in the slot to Gusev, whose shot was saved by goalie Dan Vladar.
"I guess you couldn't draw it up any better ... two goals in this game," Subban said of Hughes. "I take credit for his OT winner because prior to the overtime, I said to him, 'I heard the rumor that you get one goal and then shut it down, so are you full or do you want more?'
"He told me, 'That's not me,' and I said, 'I've got to wait and see,' and he scored the winner, so he's already listening and learning."
