What happened: The Washington Nationals marked Independence Day with a nod to the opening line of the national anthem, joining the holiday celebration in the nation's capital. The club embraced the Fourth of July occasion ahead of its holiday-date game at Nationals Park.

Why it matters: Baseball on the Fourth of July in Washington carries a symbolism no other market can match, with the anthem's words written about the city's own harbor region and flag. This year's holiday lands on the 250th anniversary of the Declaration of Independence, giving the franchise's celebration added weight.

What to watch: The Nationals return to the field for their July 4 home date, with holiday festivities continuing at Nationals Park through the weekend.
