Who hit a 582 foot home run?

The Longest Known Home Run in Professional Baseball History

On June 2, 1987, in the thin air of Denver’s Mile High Stadium, Joey Meyer launched a home run that defied belief—a staggering 582 feet. Playing for the Denver Zephyrs, the Triple-A affiliate of the Chicago White Sox at the time, Meyer sent a ball deep into the upper deck bleachers during a game against the Buffalo Bisons. It wasn’t just a home run; it was a seismic event in minor league lore.

The towering blast came in the seventh inning off reliever Mike Murphy and landed in a section of the stadium few balls had ever reached. Two nights later, Meyer stood in that exact spot for a Denver Post photo, dwarfed by the grandstand, a testament to the sheer power behind the swing. It remains the longest verifiable home run in professional baseball history, a feat made more plausible by Denver’s mile-high elevation, where the thinner air offers less resistance to a well-hit ball.

Though Meyer never became a household name in the majors—he played only 15 games for the White Sox—his legacy was sealed that night. Power hitters like Mickey Mantle and Reggie Jackson have been credited with mythical blasts, but none were measured with the same confidence. Meyer’s 582-footer stands apart: not a rumor, not a legend in the making, but a documented explosion of power.

Today, the stadium is gone, replaced by Empower Field at Mile High, but the story endures. In a game often defined by subtlety and strategy, Joey Meyer reminded everyone what raw, unfiltered power could do. One swing. One number. 582 feet. It’s still hard to believe, but the photo doesn’t lie.
