Record Holders

| 1988 | Bill Krueger | 4 | 1 year |
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.
