Record Holders
2 marks since 1990| Year | Player | W | Stood for |
|---|---|---|---|
| 1991 | Jose Martinez | 20 | still standing |
| 1990 | Marcus Moore | 16 | 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.
