It is pretty easy to delete a player from the team. Here are the steps:
Log into your TennisPoint account
Go to the “matches & teams” page in the top navigation
click on “add/edit & invite players” link (screen shot of this page below).
a. The "add/edit & invite players" page has a list of all your current players on the right side of the page
b. Find the player you want to delete and click “delete” on the far right of the person’s name in the list
c. After you click the delete link, you will be prompted and then they will be gone from your team.
