Milano missed 27 games because of an upper-body injury he sustained on a hit by New York Rangers defenseman Jacob Trouba on Dec. 9.
“The team played well all around, and it was definitely fun to get a win in my first game back,” Milano said.
Suzuki extended his career-best point streak to 10 games, and Alex Newhook scored for the Canadiens (22-25-8), who have lost two straight and eight of 11 (3-7-1). Joel Armia had two assists, and Jake Allen made 30 saves.
“We were right there. We had a chance at the end to get another one and push it to overtime,” Allen said. “It was a battle, but it was just a few costly mistakes, and they had some guys who put it in the net.”
Mantha gave the Capitals a 1-0 lead at 3:40 of the first period, scoring on a rebound from the left side of the net.
“Where you really get the meat of your goals is around the net,” Carbery said. “And so, Anthony Mantha, prime example. Protas, prime example. So, for us to get rewarded and going there, and we’re doing a better job of that of late, that’s important."
