The whole setup takes about 5 minutes. You'll be building lineups by your next game.
Select a team or create a new one.
When ON: The catcher position is left open. All outfield spots stay filled. This is the preferred option for most youth coaches since outfield coverage matters more than having a catcher (the backstop handles passed balls).
When OFF: The algorithm leaves an outfield position open instead, filling catcher normally.
Example: You have 9 players and 10 positions. With this ON, you'll see 9 players across P, 1B, 2B, 3B, SS, LF, LC, RC, RF with no one at C. The backstop catches pitches.
GameChanger is the mobile app most youth leagues use to track games, stats, and team communication. This section will include a link for all parents to download the app, instructions on how to find your team, and tips for using the chat feature to stay connected during the season.
Quick walkthrough showing how to set up your league rules, and how the fielding lineup uses them to build a compliant batting order.
Get your league's specific rules dialed in so every lineup is compliant.
Every league does it differently. Some send rules in an email. Some post a PDF on their website. Some hand you a spreadsheet at the coaches meeting. And some give you a 10-page packet at draft night and expect you to memorize it.
This section helps you organize all of that into one place. Drop your rules in however you have them, and we'll sort through them for you. Or just toggle the settings manually if you already know what your league requires.
