The NL champion Washington Nationals were at the Capitals game on Friday. And they were intimately involved all night.

Adam Eaton announced the starting lineup in the Capitals locker room while ace Max Scherzer dropped the ceremonial first baseball.

Capitals fans also had an opportunity to welcome most of the team to the game during the first period. Wes Johnson announced the Nats were in the house over the loudspeaker during a break in play. After a montage video played, the Nats were shown on the jumbotron while the Foo Fighters’ Times Like These played overhead.

The crowd roared.

As the Nationals waved to the crowd, the music then switched to Baby Shark. And most Caps fans in attendance did the Baby Shark chomp.
