An autopsy on former major league pitcher Jose Lima was completed Tuesday, but official results aren't expected until early next week.
The initial theory of a massive heart attack is still in place, said a source, and police have ruled out foul play and no evidence of drugs were found in Lima's system.
Authorities say paramedics found Lima, 37, in full cardiac arrest at his home in California early Sunday.

MLB May Seize Ownership Of Rangers
Major League Baseball may seize ownership of the Texas Rangers in an attempt to finalize a deal to sell the club, according to a source.
The group looking to buy the Rangers is headed by Pittsburgh attorney Chuck Greenberg and club president Nolan Ryan.
The Sports Business Journal first reported Monday that the league could take control of the team under the "best interests of baseball" rule and sell the group to Rangers Baseball Express to avoid creditors blocking the agreement.
