Fact-checking Forbes

In an article on the 20 greatest individual athletic feats, Forbes writes of Babe Ruth,

[N]o one has ever matched his career slugging average of .690, or his nearly inconceivable slugging average of .847 in the 1920 season.

Perhaps Forbes is unaware that Barry Bonds shattered Ruth's single-season record for slugging average. In his legendary 2001 season, Bonds slugged .863 while hitting 73 home runs.
