This day in Los Angeles Dodgers history saw Mike Piazza hit what once held as the longest home run at Coors Field. Piazza's blast on September 26, 1997, was hit off Colorado Rockies relief pitcher Darren Holmes and traveled 496 feet. Piazza's home run hit off the left-center field billboard that is located between the scoreboard and Rockpile display. However, the distance was a postgame estimate by the Rockies and ultimately was a point of contention, particularly once the Statcast era began in 2015.
