Technically speaking, Fenway Park has never seen a perfect game. But June 23, 1917 was pretty darn close to perfection. Red Sox starting pitcher Babe Ruth walked the first batter, argued with the ump about balls and strikes, and got tossed (even then, umps had short fuses). The unheralded Ernie Shore took over: the runner who walked got caught stealing second, and then Shore went ahead and retired the next 26 batters in a row. Originally, Shore was credited with a perfect game, but it’s since been downgraded to a combined no-hitter, a harsh result for Shore – and generous one for Ruth.
