Inside a BWF team tie: who plays, where and how often

Which rulebook wins

A team event is governed by two layers. The General Competition Regulations (GCR) apply everywhere, and each championship’s own regulations override them wherever the two disagree. Clause 5.1 of the Major Events table says so directly: where the two conflict, or appear to, the tournament regulations take precedence.

The editions used here: GCR version 8.0, in force 27 April 2026; the Major Events Tournament Regulations Table, version 6.0 (1), in force 8 November 2025, which covers the Thomas, Uber and Sudirman Cup Finals; and the World Junior Team Championships regulations, version 2.0, in force 26 April 2026. Unless I say otherwise, a clause number below refers to the Major Events table.

The continental qualifying stages are run by the confederations, and clause 9 lets them use a different competition structure. What follows describes the finals.

One date to note. From 4 January 2027 the Laws of Badminton (version 6.0) make a match the best of three games to 15, with two clear points needed from 14-all and a cap at 21. None of the team regulations quoted here change with it, but every points total in a tie-break will be smaller.

A tie is made of matches

Precise vocabulary saves arguments. Teams play a tie. A tie is made of matches, and a match of games. In the Thomas and Uber Cups the five matches are first, second and third singles, then first and second doubles. The Sudirman Cup plays one match in each of the five events.

Clause 12 then treats the two stages differently. In group play all five matches of every tie are played. In the knockout, a tie stops as soon as it is decided.

One of the eight permitted Thomas and Uber Cup orders. A team leading 3–0 has won the tie in both columns; only the group plays on.

In the group stage, matches four and five are what players call dead rubbers. They are dead for the tie and very much alive for the table. I come back to that with a worked group below.

Nobody has to play, and nobody has to rotate

No regulation requires every listed player to appear, or a fresh player each round. A Member nominates a team list (clause 13.1), and before each tie the manager hands the Referee that tie’s line-up, chosen from the list (13.3). The same players may be named every tie, from the first group match to the final.

The constraints are on list size and on how much one person may play.

The arithmetic is worth seeing once. A Thomas Cup tie has seven places: three singles and four doubles places. Each player can fill at most two of them, one singles and one doubles, so at least four people must play. With four, three players play twice and one plays only doubles. The table’s minimum list of four players is exactly the number one tie needs.

The Sudirman count works by gender. Men fill four places (men’s singles, two in men’s doubles, one in mixed), and so do women. At two matches each, a tie needs at least two men and two women and can use at most eight players. A man may combine any two of his three events; the cap is two matches, not one of each kind.

Timing matters as much as the count. The team list goes in 14 days before the tournament. The line-up for a tie goes in four hours before it, or eight hours before a semi-final or final, unless the Referee sets another time (Time Lines for Tournaments, Section 5.3.2, version 5.0 (1)). After that, clause 14 allows no substitution at all.

You choose who plays, not where

This is the rule people most often get wrong when they copy the format. Clause 13.2 has each Member list its singles players in order of strength, consistent with the World Rankings. BWF generates the doubles order the same way from the possible pairs. The Member may reorder only players or pairs with equal ranking points or with no World Ranking, and the Referee may amend the order. The finalised order then applies for the whole competition.

Clause 13.3 then requires each tie’s line-up to follow that order. So the manager picks three singles players, and the ranking puts them in place. First singles is the highest-ranked of the three, whoever they are.

The old trick of saving your best player for third singles, against the opponent’s weakest, is closed. What remains is the choice of whether to play someone at all, which still matters: resting a number one against a weak group opponent is legal, and the gap it leaves is filled from below.

New doubles pairings are allowed. Clause 13.3 has the Referee rank any pairing not on the list using “GCR Regulation 11.6”. In GCR version 8.0, Regulation 11.6 is the general seeding rule; the notional ranking for players without a ranking together is now 11.7.1. The cross-reference looks like it predates a renumbering, and I read it as pointing at 11.7.1. One related clause is easy to miss: under GCR 11.7.1.1, a pair that plays at least one match together in a sanctioned team tournament becomes eligible for a notional ranking after three months.

Who opens, and who gets no rest

Clause 15 lists the permissible orders of play, eight for the Thomas and Uber Cups and nine for the Sudirman Cup. It does not say who chooses among them. Clause 5.2 only makes the Referee responsible for seeing that the stipulated order is kept.

1. Thomas & Uber: eight orders

   S1 D1 S2 D2 S3S1 D2 S2 D1 S3S1 S2 D1 S3 D2S1 S2 D2 S3 D1S1 S2 S3 D1 D2S1 S2 S3 D2 D1S1 D1 S2 S3 D2S1 D2 S2 S3 D1

   First singles always opens, the singles always run 1, 2, 3, and a doubles never starts the tie.

2. Sudirman: nine orders

   MD WS MS WD XDMS WS MD WD XDXD MS MD WS WDXD MS WS MD WDXD WS MS WD MDWS MS WD MD XDMD WD MS WS XDMS XD WS WD MDWS XD MS MD WD

The lists repay counting. For each place a double-duty player might fill, count the orders that put those two matches back to back.

Counted from the eight orders in clause 15.

A third singles player who also plays doubles is the one most likely to walk straight from one match into the next. A manager who must double someone up has a structural reason to make it the first singles player. In the Sudirman Cup the extremes are a man playing doubles and mixed, back to back in only one of the nine orders, and a man in singles and mixed, or a woman in singles and mixed, back to back in four.

Whoever picks the order can only use this once both line-ups are known. If you run a tie on these rules, collect both line-ups first and choose the order second. Any one double-duty man and one double-duty woman can both be rested in at least three of the nine Sudirman orders. With several players doubling on each side, there may be no order that rests everyone. Clause 15 makes no promise of rest.

A group decided by dead rubbers

Teams in a group are ranked by GCR 16.3: ties won; head-to-head if exactly two are level; then, for three or more, tie difference, match difference, game difference and point difference, returning to head-to-head whenever a step leaves exactly two level, with lots at the end. The group-stage story sets that ladder beside the individual one. Here it is applied to four invented teams playing all five matches of every tie.

1. TiesPlover is fourth. Heron, Kestrel and Osprey each won two ties and beat each other in a circle, so head-to-head cannot help.
2. Tie diffAll three are +1. In a completed group this step can never separate teams level on ties won: everyone has played the same number of ties, so equal wins mean equal losses. It is in the ladder; it does no work here.
3. MatchesKestrel +3, Osprey +3, Heron +1. Heron is third.
4. Head-to-headExactly two are left level, so their tie decides (16.3.4.1). Kestrel beat Osprey and finishes first.

Now the detail. Kestrel led Osprey 3–0 after three matches. Osprey won the fourth and fifth, both dead rubbers, and lost the tie 2–3 rather than 0–5.

Two matches played after the tie was lost moved Osprey from third to second. That is why clause 12 makes groups play all five. A player sent out for a dead rubber in a group is playing for the table, and possibly for the quarter-final.

Retirements, injuries and conceded matches

Three rules interact here, and they are spread across two documents.

GCR 13.6.2: a player who retires or withdraws in a tie is withdrawn from all of their later matches in that tie, and nobody may replace them. If your first singles player retires injured and was also named in second doubles, that doubles is lost too. The player may play in later ties (13.6.2.1). A player disqualified during a tie may not play again in that team tournament (13.6.3).

GCR 16.3.8 fixes how the lost match counts in a group table: “as if completed without the conceding side scoring another point”. A player who retires leading 15–12 in the first game loses 15–21, 0–21. The opponent collects 42 points to 15, which reaches the point-difference step if it is ever needed.

The Sudirman Cup adds a rule for squads thinned out after arrival at the venue. If a team has only one man or one woman left, that player may play only one match, and the other two matches for that gender are conceded. Reduced to two players of any mix, the team concedes the whole tie. The Thomas and Uber regulations have no equivalent clause; there GCR 13.6.2 and the list size do the work.

Before the tie, clause 14 lets the Referee approve a substitute for a listed player who is incapacitated by illness, accident or another unavoidable hindrance. Once the line-up for a tie is in, nobody can be swapped.

How the sixteen teams are drawn

Sixteen teams reach each final: the holder, the host, four semi-finalists each from Asia and Europe, the winners from Africa, Oceania and Pan Am, and three more from the World Rankings (Schedules 2 and 3). All of them are then ranked by team strength (clause 9), which is a sum of individual ranking points.

Both players of a pair must come from the Member. Players with no World Ranking count as zero.

The group draw follows clause 10.3. Number 1 goes to the top of Group A and number 2 to the top of Group D. Numbers 3 and 4 are drawn by lot into the tops of B and C, then 5–8, 9–12 and 13–16 are drawn by lot into the second, third and fourth lines.

Every line except numbers 1 and 2 is drawn by lot within its band.

The top two in each group go through. The quarter-final draw happens straight after the group stage, and it does not reward winning the group. The four group winners are seeded 1 to 4 by team strength, from the most recent World Ranking before the draw, and placed under GCR 11.8–11.10. Everyone else is drawn by lot, with one restriction: two teams from the same group cannot meet in the quarter-finals.

A team that tops its group by beating the strongest side in it can still be the fourth seed of the knockout.

The junior version is a relay

The World Junior Team Championships, for the Suhandinata Cup, use a different tie altogether. A tie is the best of three sets, and a set is won by the first side to 55 points (clauses 12.1–12.2). Each set is five matches, one in each event, played as a relay: the first match ends when a side reaches 11, the second starts from that score and runs to 22, then 33, 44 and 55. At 54-all the next point wins.

The squad rules loosen to match. The team list is two to ten men and two to ten women (13.2). A player may play up to three matches in each set, and the same or different players may be named for each set (13.4–13.5); at least two men and two women must play in a tie (13.6). Line-ups for all three possible sets are due three hours before the tie (19.1–19.2).

The order of play is chosen by the managers, alternately. Ninety minutes before the tie the Referee tosses a coin. The winner picks the first match, the loser the second, the winner the third, the loser the fourth, and the fifth is what remains (20.3–20.8). A player in two consecutive matches gets no extra rest (17.4).

Unlike the senior finals, this format allows tactical substitutions. Between sets a team may replace players match by match, with at most three substitutions in a tie, injury and tactical combined, and only an injury substitution during the first set (16.3–16.9). A retirement concedes the match on the relay score: clause 14.2’s own example has a player retire leading 38–33 in the fourth match, and the fifth starts at 44–38 to the opponents.

For club organisers this is the most borrowable format BWF publishes. Rohan’s piece on club leagues takes it to a weeknight.

If you borrow these rules

Local team events often say “BWF rules” and mean the Laws of Badminton. The tie regulations above are a separate set of choices, and most arguments start where one was left unstated. Settle these in writing before the first tie.

1. The tie: which matches, and whether a match is best of three to 21, or to 15 under the 2027 Laws.
2. The cap per player per tie, and whether it is by count (Sudirman) or by type (one singles and one doubles).
3. Team list size and deadline, and who may approve a replacement on it.
4. Whether a published ranking order binds the singles and doubles positions. If it does not, expect your strongest player at third singles.
5. When line-ups are due, and whether both sides hand them in before seeing the other’s.
6. Who chooses the order of play, from which list, and whether that happens after the line-ups are known.
7. Whether group ties play all five matches. If match difference is in your tie-break, they must.
8. What a retirement does to the player’s remaining matches in the tie, and how a conceded match is scored.
9. The group ladder, quoted from GCR 16.3 or written out in full.

Nothing in that list requires a new rule. Each item already has a BWF answer, and you can take it or replace it, as long as you write down which.
