His big swing led to escalating home run totals that not only drew fans to the ballpark and boosted the sport's popularity but also helped usher in the live-ball era of baseball, in which it evolved from a low-scoring game of strategy to a sport where the home run was a major factor. As part of the Yankees' vaunted "Murderer's Row" lineup of 1927, Ruth hit 60 home runs, extending his MLB single-season record. He retired in 1935 after a short stint with the Boston Braves. During his career, Ruth led the AL in home runs during a season twelve times.
