⚾️On July 12, 1993 during the home run derby at Camden Yards, Mariners' outfielder Ken Griffey Jr. becomes the first and only major leaguer to hit Baltimore's B&O Warehouse on the fly. The home run is launched an estimated 460 feet. Griffey would go on to lose to Juan González in a home run playoff. By the 1993 All-Star Game, 428 home runs had cleared the walls at Camden Yards, including 4 from Griffey himself, but none had tested the windows at the B&O Warehouse until his blast.⚾️ #TheKid #Juni
