A tournament gives you one bad day and you are out. A league gives you a season: six or seven opponents at your level, one match every couple of weeks, and a table that tells the story from September to December. If you have only ever played club tournaments, the format takes a little explaining, so here is the whole thing from entry to the last round.
What a season actually looks like
A typical amateur season in Open Tennis League runs sixteen weeks and asks for seven matches. Entries stay open for two or three weeks, the draw happens the day they close, and from then on the calendar is yours to fill inside each round window. Nobody sits you down for a Saturday of back-to-back matches. You play on a Tuesday evening because that is when you and your opponent both said you were free.
The season ends with promotions and relegations, a two-week break, and a new draw. Most players stay in the same league for years and simply move up and down through the divisions.
Divisions: who you play against
When entries close, the organiser draws divisions of six to eight players of similar level. Six is the practical minimum, because one withdrawal from a group of five leaves everyone with four matches and a lopsided table. Eight is the practical maximum, because seven matches at one every two weeks already fills a season.
Level comes from the OTL rating. At sign-up you answer five questions about how long you have played, how often, what your serve does and how long your rallies last, and the app suggests a level on the 1.5 to 5.5+ scale. You can correct it. From your first confirmed result the rating takes over and the questionnaire stops mattering.
This is why a first season sometimes feels slightly wrong and a second one fits. The rating has caught up with your game. If you want to get the starting number closer on the first try, read the guide to NTRP levels before you fill in the questionnaire.
Rounds: when you play
Each division plays a round robin: everyone against everyone, once. A round usually lasts two weeks. Inside that window the two players agree a date between themselves.
In the app you mark the hours you can play. When a round opens, your opponent sees your free hours next to theirs and the app proposes the overlap. Either of you can accept, suggest another time, or move the match later by agreement. If your club is in the directory, you book the court from the same screen.
What you do not get is a text message thread of eleven messages ending in “so when?”. That is the part the format is designed to remove.
Scoring: how the table is built
Most leagues use a scheme that rewards turning up and finishing:
| Result | Points |
|---|---|
| Win in two sets | 3 |
| Win in three sets | 2 |
| Loss in three sets | 1 |
| Loss in two sets | 0 |
| Walkover received | 3 |
The point of the middle rows is that a close loss is worth something. In a division of eight, the difference between fourth and promotion is often two or three points, and those points come from three-set matches you lost but played out.
The organiser sets the scheme once, before entries open, and does not change it during the season. Ties are broken by head-to-head first, then set difference, then game difference.
Entering and confirming results
One player enters the score, the other confirms it. Nothing moves in the table until the confirmation arrives. If the score is wrong, the second player rejects it and the organiser gets a dispute to settle; until that is done the table stays exactly as it was.
The rule sounds bureaucratic and turns out to be the single thing that keeps amateur leagues honest. There is no argument three weeks later about what the third set was, because both players agreed to it the same evening.
Promotion and relegation
Two up, two down is the standard in a division of eight. The top two move to the division above for the next season, the bottom two move down, and the four in the middle stay. Some organisers use one up and one down in smaller divisions.
Over three or four seasons this sorts a field better than any rating formula, because it is built on real matches against real people who were also at the right level. A player who is genuinely 3.5 will not stay in a 4.0 division for long, and will not stay in a 3.0 division either.
What if you cannot play a round
Tell your opponent early and ask to move the match inside the round window. Most organisers allow one deferral per season to the following round. A match nobody plays and nobody reports usually counts as a double walkover, which is worth nothing to either player, so it is in everyone’s interest to find an hour.
What the format asks of you
- One match every two weeks, at a time you chose.
- Keeping your free hours roughly up to date, so the app can propose something sensible.
- Entering or confirming the score the same evening.
Everything else, the draw, the fixtures, the reminders and the arithmetic, is the app’s job. If you want to see that sequence step by step, how it works walks through it, and the frequently asked questions cover fees, disputes and private leagues.
