Welcome to the Seattle Mariners online history database provided by Sportspool.com. Here you will find Major League Baseball (MLB) Seattle Mariners records, Seattle Mariners stats, and Seattle Mariners history. Compiling a complete statistical archive is time consuming and difficult. In the early days MLB did not track stats like they do today, so some information may not be completely accurate. If you find and errors in our Seattle Mariners database please pass them along. We strive to keep our Seattle Mariners stats as accurate as possible and would appreciate any corrections or edits to be passed along.
