The Boston Red Sox and New York Yankees have one of the oldest rivalries in sports, but on Tuesday following the Boston Marathon tragedy, Yankee Stadium played “Sweet Caroline,” a Boston favorite, to support the victims of the heinous bombing.

According to the New York Daily News, the stadium grew quiet before Tuesday’s game to observe a moment of silence. A graphic ribbon with the Yankees and Red Sox logos appeared on the scoreboard, the words “New York Stands With Boston” and “Pray For Boston” circled around them.

“Our thoughts and prayers go out to the victims and the families who were affected by the bombings and our respect and admiration go out to the police, medical personnel and first responders who acted so heroically,” the Yankees said in a statement. “We stand united with the participants, volunteers, staff and spectators of the Boston Marathon and the people of Boston.”

Neil Diamond’s “Sweet Caroline” is a staple at Fenway Park, so in another show of support Yankee Stadium played Boston’s beloved song at the end of the third inning.

Diamond gave the Yankees props for their gesture, tweeting: “Thank you NY Yankees for playing ‘Sweet Caroline’ for the people of Boston. You scored a home run in my heart. With respect, Neil #OneBoston”

Fenway Park displayed a similar act of tribute in 2001 for the victims of 9/11 by playing Frank Sinatra’s “New York, New York,” the closing song at every Yankee game.

“I think it’s important that we recognize that we’re all behind the people in Boston and everyone that was involved,” manager Joe Girardi said, according to the Daily News. “You think about that being a song that’s a tradition there, it’s special to Fenway Park and the people of Boston. We’re behind them. Put the baseball teams aside, we want to be there for them.”

The Yankees also took to Twitter to show their support, posting a picture that has Yankees and Red Sox logos with the words “United We Stand” in between them.

The Red Sox appreciated the message, and wrote on their official account, “Bigger than the game. Thank you!”
