Friday: 55th anniversary of Harmon Killebrew hitting the longest home run ever at old Met Stadium

On this day, 55 years ago, Minnesota Twins legend and Major League Baseball Hall of Famer Harmon Killebrew hit the longest home run ever at the old Metropolitan Stadium in Bloomington.

“Hammerin’ Harmon” hit the home run 520 feet, but a revised estimate now puts it at 522 feet. It landed six rows into the upper deck of left field — the ball was hit so hard it shattered two seats.

The stadium was torn down to make way for the Mall of America. But in a nod to history, at Nickelodeon Universe, there’s a replica of where home plate was located at the old Met Stadium and a red seat high up on the wall, 520 feet away, showing how far that Killebrew home run went.

Target Field has a giant bronze glove 520 feet from home plate that also commemorates the historic home run.

It was just one of 573 home runs Harmon Killebrew hit in his extraordinary career, ranking him 12th on the all-time list.
