フェデラル・リーグ
In 1914, Killefer made news when it was reported that he had signed with the Chicago Whales of the Federal League, although he denied the report. When the Phillies offered him a salary increase, he decided to sign with the Phillies, which led the Federal League to file a lawsuit against him and the Phillies. A judge ruled against the Federal League and Killefer remained with the Phillies.
