Robert Dean Emslie (1859–1943) spent fifty-six of his eighty-four years in professional baseball—eight as a player and forty-nine as an umpire. When arm problems ended his career as a Major League pitcher, he turned to umpiring, serving in that capacity for thirty-five seasons, then as an umpire supervisor for thirteen years.

Emslie endured the rough-and-tumble umpire-baiting 1890s, the Deadball era, injuries from thrown and batted balls, physical and verbal assaults from players and fans, and criticism in the press. Among his most notable games, he called four no-hitters and worked as the base umpire in the famous Merkle’s Boner game between the New York Giants and the Chicago Cubs at the Polo Grounds in 1908. He often clashed with Giants manager John McGraw, who nicknamed him “Blind Bob.” Yet he was widely praised by players and his peers. Honus Wagner, the great Pittsburgh shortstop, ranked Emslie the best National League umpire he had seen during his twenty-year career. Umpires Bill McGowan and Billy Evans respectively regarded him as “the greatest base umpire of all time” and “one of the greatest umpires the game ever produced.” Emslie accepted a position as the chief of National League umpires, serving as an adviser to the National League president.

Lion of the League is the biography of an umpire whose career spanned the formative years of modern baseball.
