Double-A Single-Season Second Base Range Factor Record Progression
Every season that raised the bar, and the leader in every season between.
The Double-A single-season second base range factor record is 5.62, set by Eric Young Jr. in 2008. It has stood for 18 years. The mark has been raised 1 times since 2005.
Record Holders
2 marks since 2005| Year | Player | 2B RF | Stood for |
|---|---|---|---|
| 2008 | Eric Young Jr. | 5.62 | still standing |
| 2005 | Jayson Nix | 5.40 | 3 years |
The earliest marks here are records only in the sense that nobody had done better yet. Season length, schedule and the rules themselves have all changed, so a figure from the 1870s is not comparable with a modern one and is not offered as though it were.
