Pitcher Joe Kennedy died early Friday while at home with his family in Florida, according to a major-league source.
Kennedy, 28, spent seven years in the majors, pitching for the A's, Diamondbacks and Blue Jays last season.
As a free agent, he was not affiliated with any team for 2008. Kennedy had a career record of 43-61 with a 4.79 ERA. He reached the postseason once, as a reliever with the A's in 2006.
"The cause of death is unknown at this time," said Kennedy's agent, Damon Lapa. "The best guess at this point is either a heart attack or a brain aneurysm. The way he died was sudden. There is no reasonable explanation for what happened."
Lapa said that an autopsy would be performed.
