Mason Miller Gives Up Historic Home Run on 103.9 MPH Fastball

Mason Miller, a hard-throwing reliever recently acquired from the Oakland Athletics, gave up a two-run homer to Lourdes Gurriel Jr. on Tuesday night. The 103.9 mph fastball was the hardest hit pitch for a home run since MLB began tracking in 2008. Miller routinely throws over 100 mph, hitting 104.2 mph with his hardest pitch during the game.
