Chicago White Sox manager Tony La Russa announced he's stepping down from his position due to health concerns.
In a statement released Monday, La Russa said he had an issue fixed in the spring relating to a pacemaker installed in February. A second issue with the pacemaker was discovered on Aug. 30, prompting him to leave the team on doctor's orders. He was never medically cleared to return, leaving bench coach Miguel Cairo to serve as acting manager.
