An investigation launched Monday by the Rangers quickly uncovered that a team employee recorded manager Ron Washington's clubhouse speech prior to Game 7 of the World Series.
The team believes a person close to the employee then leaked the recorded audio to a website.
The employee, whose name the team has decided not to make public, was a member of the traveling support staff.
Texas general manager Jon Daniels, who earlier in the day declared the situation "unacceptable," Monday evening said the team has handled the situation internally.
