The World Series champs visited President Donald Trump at the White House on Monday.
Washington Nationals player Ryan Zimmerman gave Trump his own Nats jersey, with "Trump" on the back.
After the Nats walked out to a band playing "Baby Shark," Trump joked about the impeachment inquiry into him.

"America fell in love with Nats baseball. It's all they wanted to talk about. That and impeachment. I like Nats baseball a lot more," he said.
The president then thanked the team and asked them to speak at the podium one by one.
After shaking hands with players, Trump and the Nats went into the White House to the tune of "We Are the Champions."
Nats relief pitcher Sean Doolittle said he would not participate in the White House visit, he told The Washington Post.
“I want people to know that I put thought into this, and at the end of the day, I just can’t go," he told the Post.
Doolittle cited concerns about race relations, LGBTQ rights and devisive rhetoric, among others.
The following players also were not in attendance, the Associated Press reported: National League MVP candidate Anthony Rendon, outfielders Victor Robles and Michael A. Taylor, and pitchers Joe Ross, Javy Guerra and Wander Suero.
The Nats' White House visit follows a triumphant weekend for the team. They paraded through the streets of D.C. on Saturday as confetti rained down. On Sunday, they celebrated with the Washington Capitals, riding a Zamboni shirtless and pouring beer onto the ice.
Trump attended part of Game 5 at Nationals Park and was greeted with both cheers and boos. When the boos began as Trump's image flashed on the ballpark's giant video screen, the president seemed momentarily taken aback. He mouthed something to his wife, Melania Trump, while gamely trying to clap along.
But his smile froze and then faded as the boos continued and some in the crowd launched into a brief chant of "Lock him up," a version of the phrase chanted against Hillary Clinton at dozens of Trump rallies during the 2016 campaign.
