Adults - USTA

Playing fair & on schedule

Match schedule guidelines

The local league guidelines help teams keep matches valid and seasons running smoothly.

When can a match be played early?

Early play is ONLY allowed to avoid an invalid match. All matches must be played at their scheduled match times unless enough players for a valid match are unavailable.

All early play is approved by the LLC.

Team name guidelines

USTA Southern requires team names for Tri-Level, Mixed, Combo and Flex Singles to use one or a combination of:

  • Captain last name
  • Tennis facility
  • Location or CTA name

If you have a preferred combination, email the LLC. Otherwise, teams will be named “Facility name/Captain Last Name.”

What makes a valid match?

A team needs the following number of lines to play for the match to be valid:

Five-line match3 lines
Four-line match3 lines
Three-line match2 lines
If a team has enough players for a valid match at match time but not enough for a full lineup, it must forfeit the remaining lines.
