Jesús Alou, a two-time World Series champion, died Friday at the age of 80.

Alou had suffered two recent "cardiovascular accidents" but had not been dealing with a serious illness, according to ESPN.

Alou, who played on four teams in his 15-year career, won both of his World Series titles as a member of the Oakland Athletics in 1973 and 1974. 

"We are heartbroken by the passing of Jesús Alou," the A’s said in a statement.

"He was a key member of our World Series-winning teams in 1973 & 74 and will forever be a member of the A’s family."

Alou spent the first six years of his career with the San Francisco Giants, hitting .279 with 18 home runs in 633 games. 

On September 15, 1963, Alou made history when he and his two brothers, Felipe and Matty Alou, appeared in the same outfield together, according to MLB Network.
