what is the longest ball Reggie Jackson believed he hit in his career?

Reggie Jackson believed the longest ball he ever hit was his 1971 All-Star Game homer in Detroit, which he said “would have to be the longest one I’ve ever hit.” MLB later described it as an estimated 532-foot blast, while some accounts have called it 539 feet because it struck the right-field roof area and stopped before leaving the stadium.

Why it stands out

• It came off Dock Ellis in the 1971 All-Star Game.
• It hit the Tiger Stadium roof/lighting structure area.
• It has long been treated as the signature giant home run of Jackson’s career.

The short version

If you want the ball Reggie himself seemed to believe was his longest, it was that 1971 All-Star Game shot.
