Babe Ruth – 60
Nobody knew that Ruth set a record that would stand for over 30 years when he hit his 60th home run in 1927. It wasn’t until 1961 that Roger Maris finally eclipsed him. Ruth came close to this tally on several occasions but finally hit it as part of the Yankees’ Murderer’s Row.
Unsurprisingly this was one of the most impressive individual seasons he posted. With a slugging percentage of .772, Ruth set the standard for the rest of the league to follow. There’s a reason why he entered American folklore and became one of the nation’s heroes of the 20th century (via History).
