Giles' presidency also saw the National League widen its advantage over the American League in the signing of African-American and Latin American players, resulting in a three-decade-long domination of the Major League Baseball All-Star Game. In clubhouse meetings before the midsummer classic, Giles famously would exhort the NL's players to uphold their league's honor. During his tenure, the National League won 16 of 22 All-Star games played, with one tie. (Two games were played each year from 1959 to 1962.) The NL also won ten of 18 World Series during Giles' term.
