Authorities say paramedics found former major league pitcher Jose Lima, 37, in full cardiac arrest at his home in Pasadena early Sunday, and he was taken to Huntington Memorial Hospital where he was pronounced dead.
A statement from the Pasadena Police Department says a specific cause of death is unknown, and Los Angeles County coroner's officials will perform an autopsy.
Police detectives also responded to the scene because of the undetermined cause of death and will work with the coroner's office, the statement said.
Lima's wife Dorca Astacio said the cause of death was ruled a heart attack.
