Babe Ruth – 54
Ruth set the standards for the rest of baseball by breaking past 50 home runs for the first time. He slugged 54 in 1920 as he showed the sport how to play. It was a remarkable achievement but Ruth went even further over the next few years. He didn’t stop there as his game continued to develop.
Before 1920, Ruth held the home run record with 29. But then the live ball era began and new possibilities opened up for the Yankees star. In the end, Ruth was operating in a different arena from his rivals because he went past 50 three times before anybody else achieved it (via Bleacher Report).
