The ball does fly out of Coors Field. And Denver's mile-high altitude adds a little distance. It's well-documented.
Still, 478 feet? Coors-aided or not, that's impressive.
Jackie Bradley Jr. blasted the longest Red Sox home run tracked by Statcast (which started in 2015) with his second-inning shot to the third deck in right field at Coors on the first pitch he saw from Colorado Rockies right-hander Rico Garcia, making his major league debut.
The solo shot had an exit velocity of 112.1 mph and gave Boston a 2-0 lead. Its distance on Statcast topped the 469-foot shot by Hanley Ramirez at Fenway Park on April 29, 2017, off ex-Red Sox right-hander John Lackey, then pitching for the Chicago Cubs.
The longest home run in Fenway history was 501 feet, hit well before the Statcast era, in 1946 by Ted Williams. It's now marked by a red seat in the right-field bleachers.

The longest homer at Coors was hit last Sept. 5, a 505-foot shot by the Rockies' Trevor Story off San Francisco Giants left-hander Andrew Suarez.
Garcia - and Red Sox fans who saw it - will long remember the first major league homer he gave up.
