Tennis Club Singles League
Twelve members, one summer, every player meets every other player once
A club singles league is a round robin stretched over a season: each member plays every other member once, the two players book a court between themselves, and the result goes into a shared table. In JudgeMate the tennis league generates the fixtures, applies two tie-break sets with an optional 10-point match tie-break, and ranks players by set margin. Organisers confirm results; a player can keep score live through the match's judge link without an account.
A season, from the sign-up list to the last match
Before the season. The club posts a list in the clubhouse or the members' group. Ten to twelve names is a good field for one division. With more, open a second division.
Opening weekend. You publish the fixtures and the table on one link. Every player can see the full list of opponents from day one, so the strong ones get booked early instead of in the final fortnight.
Mid-season. Players arrange matches themselves, usually by message, around their own court bookings. The result reaches the league the same day.
The last month. A few matches are always outstanding. Set a cut-off date at the start, and decide in advance who gets the walkover if a match is still unplayed by then. You can only end the season once every result is confirmed, so each open match needs a result or a walkover first.
After the cut-off. You close the season, the table is frozen and the top of the division knows who plays in the stronger group next year.
How many players can one division take?
A single round robin with n players has n(n−1)/2 matches:
- 8 players: 28 matches, 7 rounds
- 10 players: 45 matches, 9 rounds
- 12 players: 66 matches, 11 rounds
With an odd number, one player has a bye in every round, so 11 players need 11 rounds for 55 matches.
The limit in tennis is court time and the weather. A player in a twelve-player division owes eleven matches, and every rained-off evening pushes one of them back. Home and away rounds double the count to 22 matches per player in 22 rounds: a match every week for 22 weeks with no slack for rain, or 44 weeks with a two-week window per round.
If the list grows past twelve, split it into two divisions by level. Both finish sooner, and the matches are closer.
Two sets and a match tie-break
The ITF Rules of Tennis 2026 allow a match tie-break in place of the deciding set (Appendix VI): at one set all, the players play a tie-break to 10 points, won by a margin of two. The ITF World Tennis Tour Juniors Regulations 2026 use exactly this for round-robin groups: two tie-break sets and a 10-point match tie-break in place of the third set.
In a club league the reason is court time. A third set can run past the end of a court booking, while a match tie-break is a single game to 10 points.
A new tennis league in JudgeMate starts at best of three sets, six games per set, a tie-break to 7 at 6-6 and advantage scoring. Two switches in the league format change it:
- Super tie-break in the deciding set turns the third set into a match tie-break to 10.
- Golden point replaces deuce and advantage with a single deciding point, the ITF No-Ad method.
Both switches can be changed later in the league settings, and any single match can override them, for example a final-round decider played as a full third set.
Who records the score
In the league module, results are confirmed by the organisers: you and any co-organisers, each with a JudgeMate account. Players see their fixtures and the table, but they cannot edit a match.
Players still have two ways to get a score in:
- Live, on court. Open the match, start the scoreboard and send the Judge link to one of the two players. They keep score point by point on a phone, no login needed, and the board follows the tennis serve order, tie-break rotation included. When the match ends, the Next step bar at the top of the league shows Confirm result.
- Afterwards, by message. A player sends you the sets won and you type them into the match with Enter result manually.
The difference shows up in the table. A match kept on the scoreboard brings its games with it, so the games tie-break can use them. A result typed by hand carries sets only.
If you want players to report and the opponent to confirm with nobody in between, run the same round robin as a singles category inside an event. There, outside a knockout bracket, either player reports and the other confirms.
Ordering the table
A tennis league counts its table in sets and starts with the 3/2/1/0 system: 3 points for a 2-0 win, 2 for a 2-1 win, 1 for a 1-2 loss and 0 for a 0-2 loss. A player who fights to a match tie-break and loses still takes a point.
Prefer to rank by wins, the way a tournament group does? Switch off 3/2/1/0 points by set margin; the table then gives 2 points for a win and 1 for a loss. When everyone has played the same number of matches, that order equals the order by wins.
For players level on points, the Tie-break order list has four options. Two are custom orders: head-to-head, then set ratio, then games ratio; or set ratio, then games ratio, then head-to-head. A new league starts with head-to-head first. The other two are federation rules: the ITF Juniors Regulations 2026 (Reg. 57) and the Polish PZT tournament rules 2025 (IV.7.4). Both rank by wins. Two players level are split by their match, three or more by sets and then games, as percentages under ITF and as differences under PZT. Once you pick federation rules, a win is worth 1 point and the 3/2/1/0 switch disappears. A match tie-break counts as one set and one game won, which is also how the ITF Juniors Regulations 2026 count it in round-robin standings (Reg. 57).
Tell your players in advance how walkovers count. Under ITF junior rules the matches of a player who gave a walkover drop out of the standings, and the table does exactly that when the ITF rules are picked. With a custom order a walkover enters as 2-0 in sets, and the results already played stay in the table.
Setting the league up in JudgeMate
Start once the sign-up list is closed. Creating a league needs an account.
- Open Create for tennis and pick League.
- Name it, add the season ("Summer 2027") and choose Public so members can open the table without signing in.
- In the format step, switch on Super tie-break in the deciding set, leave Golden point off unless your club plays No-Ad, and decide on table points and tie order.
- Add each member as a participant. Tennis league entries are single players, no roster.
- Generate the schedule. Dates and times are editable per match, so give each round a window of one or two weeks.
- Add your courts as playing areas of type Court, so a match can carry a court and a time slot.
- Export the schedule as PDF for the clubhouse board and share the league link in the members' group.
From then on the Next step bar tells you what is due: the next match to play, a result waiting for confirmation and, at the end, End season.
What the league does not do
- No challenge ladder. The league is a round robin. A box where players challenge the rung above has no format here.
- No rating link. Results do not feed the PZT ranking, the DTB LK, the ITF World Tennis Number or UTR, and none of them is read in.
- No team ties. A league where clubs meet in a tie of several singles and doubles is not a single match type here; a side in a tennis league is one player.
- No advantage set and no 10-point tie-break at 6-6 in the final set. Every set has a tie-break at 6-6, and the super tie-break replaces the third set.
- No reminders or court booking. JudgeMate sends no email, SMS or push messages and does not reserve courts. Chasing an unplayed match stays your job.
- No self-entry in the league module. Players do not add themselves or report scores there; for that, use a singles category inside an event.
Clubhouse sheet, spreadsheet or a league page
The sheet on the clubhouse board is enough for most club leagues. It works until someone has to work out who is ahead: with 3/2/1/0 points, set ratio and games ratio, a fair order means an evening with a calculator.
A shared spreadsheet handles the arithmetic if somebody builds it, but the tie rules end up in one person's formulas, and a member reading it on a phone sees a grid of cells.
A league page keeps fixtures, results and the table behind one link and applies the tie order you chose. For a one-off match outside the league, the free tennis scoreboard runs without setting anything up. Rule disputes are covered in how tennis scoring works, and other season shapes in tennis tournament formats explained.
