More than a bracket tool

What racket-sport clubs actually need.

Brackets are the start, not the finish

Generic bracket tools end where CenterCourt begins. Both sides confirm scores, disputes route to the admin, and overrides leave an audit trail — instead of one organizer typing in whatever number was shouted across a court.

Recurring leagues, not one-off events

Most racket-sport clubs don't run a single weekend tournament. They run a season. CenterCourt generates round-robin schedules, publishes rounds on your cadence, and keeps standings live between weeks.

Challenge ladders for club play

Tournaments answer 'who won this weekend.' Ladders answer 'who's the strongest at the club right now.' CenterCourt runs both, with the same player roster.

Built for tennis and pickleball, not generic events

Sport-specific scoring defaults, tiebreaks that match how racket sports are actually ranked (set %, game %, head-to-head), and a mobile experience tuned for submitting a game score courtside.

See it in action

Brackets, then everything Challonge doesn't do.

1. The bracket you came for.

Single elimination, double elimination, Swiss, round robin, or pool play. Auto-seeded, auto-advancing, with byes handled correctly when your field isn't a clean power of two.

A single elimination pickleball tournament bracket showing 8 players seeded across the first round, with two completed matches already advancing winners into the quarterfinals — Single and double elimination feel familiar. Swiss, round robin, and pool play add standings-based formats from the same screen.

2. Scores get confirmed, not just typed in.

Bracket tools usually trust whoever types the score first. CenterCourt runs every score through both sides — pending confirmation, confirmed, or disputed — with admin overrides recorded when something needs you.

A confirmed tournament match showing the winning side highlighted in the bracket with the game-by-game score visible underneath both players — Scores move through submitted, pending confirmation, confirmed, disputed, or admin override — disputes route to the admin instead of becoming a group-chat argument.

3. Run a season, not just a weekend.

Most clubs run recurring leagues, not one-off events. CenterCourt generates the round-robin schedule, publishes rounds on your cadence, and keeps the rest of the season visible to every player.

A 7-week league schedule with Week 2 expanded, showing 1 confirmed match, 1 pending confirmation, and 2 awaiting scores — and upcoming weeks listed below — Every player sees the current round and the season ahead. Schedules generate themselves.

4. Challenge ladders for club play.

Tournaments tell you who won this weekend. Ladders tell you who's the strongest at the club right now. Players issue challenges, the system enforces cooldowns and deadlines, and rankings update the moment a score confirms.

A pickleball challenge ladder with 8 players ranked, an active pending challenge visible between two players, and a response deadline counting down — Challenge distance, cooldowns, and response deadlines — configured once, enforced forever.

5. Players submit scores from the court.

Generic bracket tools feel admin-centric — one person at a laptop, typing for everyone else. CenterCourt is built for the player's phone first. Submit a game-by-game score in seconds, then the opponent confirms.

Mobile view of the score submission form with Game 1, Game 2, and Game 3 fields and a 'Match didn't finish' checkbox — No app to download. Players use the same browser they already have open.

6. Standings that rank racket sports properly.

Set percentage, game percentage, head-to-head, points scored — pick the order that matches how your club has always done it. Critical for Swiss, round robin, and pool play, where wins alone won't break a tie.

Live standings for an 8-player pickleball league showing rank, win percentage, total wins, point and game percentages, and tiebreak priority — Configurable tiebreaks resolve ties automatically. No eyeball-it-and-pick-one moments.

Common questions

Is CenterCourt a Challonge replacement?

Yes — with more built around the bracket. CenterCourt runs the same single and double elimination brackets, plus Swiss, round robin, and pool play. It also runs ongoing club leagues and challenge ladders from the same player roster, with both-sides score confirmation and sport-specific tiebreaks baked in.

Can I run a single-weekend tournament with it?

Yes. Spin up a bracket, seed your players, publish, and run the event. The interface is built for racket sports — sport-specific scoring, confirmation flows, and standings — but a one-off bracket works exactly like you'd expect.

Do players have to pay?

No. Players join your tournament, league, or ladder for free. Only the organizer needs a paid plan, starting at $2.99/month with a 30-day free trial.

What sports are supported?

Tennis, pickleball, padel, ping pong, and paddle. Each sport ships with sensible scoring defaults you can override per league.

Can both sides confirm a score?

Yes. Score submission goes pending_confirmation → confirmed once the opposing side signs off. Disputes route to the admin, who can override with a recorded reason. No more generic-bracket-tool ambiguity about who won.

Does it work on mobile?

Yes. Players submit scores, check brackets, view standings, and respond to ladder challenges from the same browser they already have open. No app download required.
