(February 1, 1875 – January 28, 1965) was an American professional baseball player and manager.
He played as a catcher in Major League Baseball, most notably for the Chicago White Sox.
Although he was a relatively weak hitter, he sustained a sixteen-year playing career by being one of the best defensive catchers of his era.Sullivan's reputation as a defensive standout is enhanced because of the era in which he played.
In the Deadball Era, catchers played a huge defensive role, given the large number of bunts and stolen base attempts, as well as the difficulty of handling the spitball pitchers who dominated pitching staffs.
He had to catch every type of pitch imaginable, such as shine balls, spitballs, knuckleballs, and emory balls.
