Aparicio quickly became an integral member of the teams of the mid-1950s, who were known for their speed and strong defense. Over the next decade, Aparicio set the standard for the spray-hitting, slick-fielding, speedy shortstop. He combined with second baseman Nellie Fox to become one of the best double play combinations in major league baseball. Aparicio once again led the American League in stolen bases and assists in 1957 as the White Sox would hold first place until late June before finishing the season in second place behind the New York Yankees.
