If games or practices were created by an organization such as a city recreation department or a Little League Baseball organization, then you can't change games or practices.
If games or practices were created by you or another individual using TeamSideline.com, then to delete an event from your schedule, click on the team name in the left column, and then click the Events tab. Any event you would like to remove, just click the red . If you have more than 10 events, click the Next button to go to another page and see the next group of 10 events.
