Brucker was the son of Earle Brucker Sr., who played five seasons in the major leagues for the Athletics himself.[2] When Earle Sr. joined the Athletics coaching staff in 1941, Earle Jr. was made the bullpen catcher at the age of 15.[3]
Earle Sr. had gotten a 50-year lease on a property near Gillespie Airport, which he attempted to lease to the Detroit Tigers as a spring training facility. When they declined, he turned the property into a racetrack, fairgrounds, and high school football stadium.[1] He turned the property over to Earle Jr. in 1958. One of his sons, Steve Brucker, took over the track but was murdered in 2003.[4][5] With the death of Brucker and the speedway lease ending in 2005, the track shut down after the 2004 racing season.[6]
Brucker died at his home in El Cajon on March 28, 2009.[1]
