Fenway Park offered up a number of tributes to the Boston Marathon victims at yesterday's Red Sox game, a matchup with the Kansas City Royals that had been delayed due to Friday's manhunt for Dzhokhar Tsarnaev. But the biggest surprise may have been Neil Diamond's appearance. He performed "Sweet Caroline," a song Boston fans typically sing during the seventh-inning stretch at Fenway Park, and led the crowd in singing along, E! reports. Making the day even sweeter for the city: The Sox beat the Royals 4-3, the AP reports.
