Play-offs — three champions

Three separate titles are decided after the round-robin season wraps: Men's Doubles, Women's Doubles, and Mixed Doubles. Each one ends in a champion pair.

Every event shares the same backbone — a round-robin group (the "semis") that re-seeds the players, then a single balanced final where the group's best and worst are split onto opposite teams. It is the classic ATP/WTA Finals idea: a group stage, then a final. Because the season ranks individuals (partners rotate all year), the play-off never invents fixed teams — it needs the top people, and pairs them on the night. The events differ only in how many enter the group: Men's and Women's each take the top 4; Mixed takes the top 2 men + top 2 women.

How the group is scored. Inside every play-off group the matches are ranked by the same season rules — Win % → Games % → head-to-head → countback. Any remaining tie is broken in favour of the higher season seed, so a strong summer keeps its reward. The higher season seed also gets the traditional #1 courtesy in the final: choice of ends and first serve.

Men's Doubles

Top 4 · round-robin → final

The four highest-ranked men on the season ladder qualify — call them Q1–Q4 (Q1 is the season #1). They play a three-match round-robin as the "semis" — everyone partners everyone — then re-seed into one balanced final. Because the season ranks people, the play-off needs the top four men, not eight fixed team-mates.

Stage 1 · The round-robin group (the "semis")

The four qualifiers play everyone-partners-everyone — three doubles matches, each man partnering each of the other three exactly once:

MatchTeam ATeam B
1Q1 + Q2Q3 + Q4
2Q1 + Q3Q2 + Q4
3Q1 + Q4Q2 + Q3

The three matches produce a fresh 1–4 order (R1–R4), scored by the season rules — Win %, then Games %, then head-to-head, then countback — with ties going to the higher season seed.

Stage 2 · The final

The re-ranked order sets the same balanced final — strongest with weakest:

R1 + R4Finalist team 1
vs
R2 + R3Finalist team 2

The winning pair are the Men's Doubles champions. The higher season seed keeps the #1 courtesy — choice of ends and first serve.

Women's Doubles

Top 4 · round-robin → final

The women's play-off runs on the same four-player format — the top four of the women's ladder (Q1–Q4) play a three-match round-robin, then re-seed into a balanced final. The smaller women's draw fits this shape perfectly, because it needs four people, not eight fixed team-mates.

Stage 1 · The round-robin group (the "semis")

The four qualifiers play everyone-partners-everyone — three doubles matches, each woman partnering each of the other three exactly once:

MatchTeam ATeam B
1Q1 + Q2Q3 + Q4
2Q1 + Q3Q2 + Q4
3Q1 + Q4Q2 + Q3

The three matches produce a fresh 1–4 order (R1–R4), scored by the season rules — Win %, then Games %, then head-to-head, then countback — with ties going to the higher season seed.

Stage 2 · The final

The re-ranked order sets the same balanced final — strongest with weakest:

R1 + R4Finalist team 1
vs
R2 + R3Finalist team 2

The winning pair are the Women's Doubles champions. The higher season seed keeps the #1 courtesy — choice of ends and first serve.

Mixed Doubles

Top 2 M + Top 2 W · round-robin → final

The mixed rankings send the top 2 men and top 2 women from the mixed ladder to a four-player round-robin — label them M1, M2 (men) and W1, W2 (women). Each man partners each woman once, so the "semis" are just two matches, and every player plays both.

Stage 1 · The round-robin group (the "semis")

Two matches settle the group — each man partners each woman exactly once, so everyone plays both nights:

Semi matchTeam ATeam B
1M1 + W1M2 + W2
2M1 + W2M2 + W1

The two matches produce a fresh order of the four — an updated #1/#2 man and #1/#2 woman — scored by the season rules (Win %, then Games %, then head-to-head, then countback), with ties going to the higher season seed.

Stage 2 · The final

The re-ranked order sets a balanced mixed final — the top man plays with the second woman, and the second man with the top woman, so the two teams are as even as possible:

#1 man + #2 womanFinalist team 1
vs
#2 man + #1 womanFinalist team 2

The winning pair are the Mixed Doubles champions. The higher season seed keeps the #1 courtesy — choice of ends and first serve.

Why this format is fair and on-format: only the top of each ladder makes it (the reward for a strong season); everyone in the group plays several matches, so no single off day ends a run; teams are seed-balanced, never stacked, and no arbitrary fixed pairs are invented — the season ranks people, and the group pairs them; and the balanced final keeps the two strongest apart so the title is genuinely contested. The men's and women's draws each fit the four-player group perfectly, and the mixed draw does the same with two men and two women, because each needs four people, not eight.

Fully settled: three champion pairs. Men's and Women's each take the top 4 into a three-match round-robin; Mixed takes the top 2 men + top 2 women into a two-match round-robin. All three re-seed the group and finish with a balanced paired final.
