Joseph J. "Sport" Sullivan (1870-?) was an American bookmaker and gambler from Boston, Massachusetts who helped to initiate the 1919 Black Sox Scandal.
Sullivan was a known gambler in the Boston area who reportedly bet heavily on the 1903 World Series and was arrested for gambling on baseball in 1907. In 1919, Sullivan was living in the Boston suburb of Sharon, Massachusetts. In September 1919, Sullivan met with Chicago White Sox' first baseman Charles Arnold 'Chick' Gandil at Boston's Hotel Buckminster and conspired with Gandil to perpetrate a fix of the 1919 World Series. It has been disputed which of the two men initiated the meeting. Gandil had known Sullivan since 1912, and he later maintained that Sullivan approached him concerning the plot to throw the series. At Sullivan's suggestion, Gandil recruited several teammates to intentionally lose the games. Sullivan met with noted organized crime boss Arnold Rothstein, who agreed to bankroll the fix for $80,000. Rothstein provided an initial $40,000 for Sullivan to distribute to the involved players; however Sullivan kept $30,000 for his own wagering and gave only $10,000 to Gandil.
After the scheme had been exposed, Sullivan did not testify in front of the Chicago grand jury hearing in October 1920, because William J. Fallon, the lawyer of Arnold Rothstein, persuaded Sullivan not to do so. If Sullivan did testify, it would probably expose the fact that Rothstein has been the one providing the money for the Black Sox players to fix the Series. Still, he was later indicted on nine counts of conspiracy to defraud. Sullivan reportedly was paid by Rothstein to flee to Mexico so that he would not go to Chicago to testify in front of the Grand Jury. Sullivan was never arrested nor appeared at the trial, which started in June 27, 1921. The trial ended in an acquittal for all the defendants.
Sullivan appeared at Yankee Stadium during the 1926 World Series. He was recognized by Ban Johnson, who had police escort Sullivan out of the stadium
Arnold “Chick” Gandil, first baseman for the Chicago White Sox, meets with Joseph “Sport” Sullivan, a gambler, and tells him that the World Series can be bought.
Charles “Swede” Risberg, shortstop, Fred McMullin, infielder, and Eddie Cicotte, pitcher, join Gandil in a plot to throw the World Series.
George “Buck” Weaver, third baseman, Claude “Lefty” Williams, pitcher, Oscar “Happy” Felsch, center fielder, meet with Gandil, Risberg, McMullin and Cicotte to devise a plan. By some accounts, “Shoeless” Joe Jackson, left fielder, was also present.
Cicotte runs into William “Sleepy Bill” Burns, a retired baseball player turned gambler, who expresses his interest in the fix. Burns asks Billy Maharg, an ex-fighter, to help him get the money together to pay the players.
Burns and Maharg approach Arnold Rothstein, an infamous gambler of the time, and Abe Attell, his associate, to supply the money to fix the World Series. Rothstein turns them down.
Attell notifies Burns that Rothstein has changed his mind (a lie) and will put up $100,000 but does not want his name mentioned.
Sullivan approaches Rothstein separately with the same proposal as Burns and Maharg. Rothstein shows interest because he has more respect for Sullivan. He sends Nat Evans, his associate, to find out if the players can be bought.
Rothstein sends $40,000 to be given to the players. Sullivan gives Gandil $10,000 and bets the rest on the series. Another $40,000 is placed in a safe at the Hotel Congress in Chicago to be paid out after the series.
