Every pickleball doubles game starts with server 2, not server 1. Here is exactly why, and what it means for the score.
In doubles, the serving team only gets one server before their first side out - and by rule, that player is called server 2, not server 1. The game starts at 0-0-2.
This exists to balance the total number of service turns each team gets across the game. Without it, whichever team served first would always get an extra service turn.
In pickleball doubles, the score is called as three numbers: the serving team's score, the receiving team's score, and the server number (1 or 2) - for example "4-2-1".
The third number tells everyone on court which of the two serving players is currently serving. It matters because losing a rally on serve as server 1 does not end your team's turn - it just passes the serve to server 2.
No. Server numbers only exist in doubles, since there are two players per side who take turns serving. In singles, there is one player per side, so the score is called with just two numbers - no server number needed.
Yes. Scorepion shows the correct score format, including the server number, throughout the whole match. Nobody has to remember whether it is server 1 or server 2.
