TLS was last updated
on October 15, 2025.

TLS uses all of a player's league results to create
a rating for the player based on the NTRP rating
system.
* Rating lists by area and facility.
* Ratings for each of a player's matches.
* Section and national team rankings.
* Team scouting pages.
* Yearly historical summary of a player's league play.
* Follow TLS Tennis League Stats on Facebook.
Please send questions and comments to
admin@tennisleaguestats.com.
I read all emails and try to answer all
reasonable questions. Please read the
"TLS Rating Requirements" paragraph on the
Area pages instead of sending an email
asking what causes an "n/a" rating.
The USTA does not create
or endorse TLS ratings.
