Tom Wilson also scored for the Capitals (21-15-6), who played their third straight without Alex Ovechkin because of a lower-body injury.
“Every time you miss the big piece like Alex, a lot of guys have to step up,” Washington forward Evgeny Kuznetsov said. “Maybe not the most exciting game tonight, but we got the job done. That's what's most important for us.”
John Gibson made 26 saves for the Ducks (15-28-1), who have lost three of their past four games. Anaheim was playing the second of a back-to-back after a 5-4 overtime win at the Florida Panthers on Monday.
“We stayed, I thought, pretty sound defensively; didn’t give them too much, even though we weren’t really sharp with our passing and our execution,” Ducks coach Greg Cronin said. “Gibson kept us in the game, and we weathered a little bit of the surge they had in the third period and then we came on [but] we couldn’t score.”
Bear, who signed a two-year contract with the Capitals on Dec. 28, made it 1-0 during 4-on-4 play at 19:22 of the first period. Nick Jensen’s shot from the right face-off circle deflected off T.J. Oshie, and Bear controlled the puck before scoring over a diving Gibson.
It was Bear’s first goal since Jan. 15, 2023, which came with the Vancouver Canucks against the Carolina Hurricanes.
“You forget how that feeling feels,” Bear said. “It's definitely nice to get that out of the way, and now I can just have fun and not think about it.”
