Most modern statistical analyses place Williams, along with Ruth and Barry Bonds, among the three most potent hitters to have played the game. Williams's baseball season of 1941 is often considered favorably with the greatest seasons of Ruth and Bonds in terms of various offensive statistical measures such as slugging, on-base and "offensive winning percentage." As a further indication, of the ten best seasons for "OPS", short for "On-Base Plus Slugging Percentage", a popular modern measure of offensive productivity, four each were achieved by Ruth and Bonds, and two by Williams.
