Major League Baseball is investigating claims of racial discrimination in the Seattle Mariners organization made by a former employee.

"MLB is aware of the allegations made by a former employee of the Seattle Mariners regarding the conduct of Club employees. Consistent with our policies, we are investigating the allegations," the commissioner's office said in a statement.

The Mariners have denied the allegations of racial discrimination made on social media by Lorena Martin, the team's former director of high performance.

The team said in a statement that Martin was fired last month, on Oct. 10. The team did not give a reason for her termination.
