The last time that the Red Sox and the Dodgers played in the World Series was a hundred and two years ago, in 1916, when the Dodgers were known as the Robins and played in Brooklyn, at Ebbets Field. The Red Sox had been playing games at Fenway Park since it opened, in 1912, but for the 1916 Series they borrowed the significantly larger stadium of their National League neighbors, the Boston Braves. When the Dodgers, now of Los Angeles, open their series against the Sox, on Tuesday night, it will be at Fenway, in front of roughly seven thousand fewer fans than watched the opener between the Sox and the Robins back in 1916.
