As manager William Wilson Hallman (March 31, 1867 – September 11, 1920) was an American professional baseball player.

The court pointed out that the contract was so one-sided (allowing the team to dispense with Hallman for virtually any reason) that it was unenforceable.

[1] Although he was primarily a second baseman, he did eventually play every position on the diamond,[2] including one game as a pitcher in 1896.

[4] Hallman owns one significant Major League recorded as the only player in history to improve his batting average in nine consecutive seasons,[5] beginning at .206 in 1888 and ending at .320 in 1896.

Though a handful of players of Hallman's generation also made appearances in theater, most of them were brief parts with little dialogue.
