Single Season Leaders for At-Bats / RBI Ratio

What percentage of a major league baseball player's at-bats result in a run being drive in and how often over the course of a major league season were they driving in the runs? The list below reflects those who over the course of a single season had the best at-bats / runs batted in ratio.

Important notes: One-hundred single season games played are needed to make this list and a bold faced entry denotes that the player was active during the previous Major League season.

"As a baseball fan I had known about Hack Wilson for a long time. He probably hit the most home runs ever for a guy with size 5 ½ feet. Now Wilson would probably be weeded out in the minor leagues based on physique alone. But even though he was an odd-looking character, he was the up and coming rival to Babe Ruth. He was the National League version of Babe Ruth." - Author Clifton Parker in Fouled Away: The Baseball Tragedy of Hack Wilson (McFarland, 2000)
