While Shoeless Joe Jackson racked up a .375 series avg. in the 1919 series, he went 6 for 11 in the the games the Sox won and 6 for 21 in the losses. Some of the hits in the losses, including his only HR, came when the Reds had the game wrapped up. I believe strongly that he conspired to throw the series.
His performance, even though there were no blatant misplays, was inconsistent.

He receivedd $5,000 in cash, and admitted his involvement to a grand jury. When he was banned after the 1920 season, he changed his tune and denied involvement. His career avg, is still one of the highest history.

Ty Cobb and Tris Speaker allegedly fixed a game in Sept. 1919 that was brought to light in the late 20s. The AL founder and president (or VP) was fired over his coverup. As the evidence was not as strSox scandal, Cobb and Speaker were removed from their respective teams. I believe strongly that they both fixed the game.

Cobb by the way bet on the White Sox to win the 1919 series.
