Go to All Umpire Assignments. If your role does not display that link on your home page, go to View Your League, and click on Umpire Assignments next to the Season Name. Define the date range, and if you want the schedule for all the dates listed, click on All Dates Below. WARNING: If you have a large league, it might take awhile to generate the full schedule. Once the schedule is generated, click on Export Assignments Table as a tab-delimited file.

The resulting page can be saved from your browser file menu. It can then be opened in excel.
