Tiebreak serve order: who serves next?

General singles · seven-point tiebreak

Before you enter a score

Use this only when your match uses a seven-point tiebreak with a two-point winning margin. It does not cover doubles, ten-point match tiebreaks or alternative end-change rules. Check your competition's format.

1. Keep the same two players labelled A and B throughout. These letters do not mean the server, receiver, left side or right side.
2. Choose the player who served the very first tiebreak point. Enter the points already completed, in A–B order, not the set's game score.
3. Read the next serve from the server's view facing the net: deuce is the right side, ad is the left side. A change of ends does not change these labels.

Whole numbers from 0 to 99. Enter 0–0 before the first point.

Examples when A serves first

Each score is A–B. These are separate examples, not a point-by-point record.

The rule behind the result

• The first server serves one point. The other player then serves two points, followed by two points each in turn.
• Start on the deuce side and alternate serving sides after every point. During the tiebreak, change ends after each six completed points in total.
• Win at least seven points with a lead of two. 7–5 and 8–6 finish the tiebreak; 7–6 is still in progress.
