WASHINGTON — Tom Wilson scored the go-ahead goal on a power play with 7:20 left and the Washington Capitals beat the Pittsburgh Penguins 5-2 on Thursday night for their second victory in six games this season between the rivals.

Nicklas Backstrom scored his team-leading ninth goal of the season, and T.J. Oshie had one for the highlight reel in the third period when he dived one-handed to poke the puck past Tristan Jarry.

Wilson’s tap-in on the power play helped Washington respond after blowing a 2-0 lead with back-to-back goals against 3 minutes apart.
