In 1915, Ruth batted .315 and topped the Red Sox with four home runs. Braggo Roth led the AL with seven homers, but he had 384 at-bats compared to Babe’s 92. Ruth didn’t have enough at-bats to qualify, but his .576 slugging percentage was higher than the official leaders in the American League (Jack Fournier .491), the National League (Gavvy Cravath .510), and the Federal League (Benny Kauff .509).

During his five full seasons with the Boston Red Sox, Babe Ruth established himself as one of the premier left-handed pitchers in the game, began his historic transformation from moundsman to slugging outfielder, and was part of three World Series championship teams. After he was sold to the New York Yankees in December 1919, his eye-popping batting performances over the next few seasons helped usher in a new era of long-distance hitting and high scoring, effectively bringing down the curtain on the Deadball Era.
