The 2019 season saw the most homers ever, obliterating a record set just two years before. This historic area for the home run has transformed the way the game is played. Diamond reveals that the secret behind this unprecedented shift isn't steroids or the stitching of the baseballs, it's the most elemental explanation of all: the swing. He tracks a group of baseball's biggest stars who remade their swings under the tutelage of a band of renegade coaches, and remade the game of baseball in the process.
