Each night the Reds play the "Twitter DJ" song of the game, but that was the one song seemed fitting for a miniature tribute to fans in Boston.
"Tonight's song of the game has become a part of the everyday game day experience at Fenway Park. Here is Neil Diamond," said Reds public address announcer Joe Zerhusen.
"Sweet Caroline" has traditionally been played during the eighth inning at Red Sox home games. Many teams around Major League Baseball paid homage to Boston and the Red Sox by playing the song -- including the rival Yankees on Tuesday night.
As it was "Bark in the Park" night at Great American Ball Park, fans and some of the 600 dogs in attendance were shown on the video board merrily singing along.
