Fielding rotation

Fair playing time, built for you.

Pick your league, pin your pitcher and catcher, and DiamondKeeper builds a fielding rotation that meets your league's mandatory-play rule — then shows a green check, or exactly who falls short.

Done at the kitchen table, not in the dugout

Three steps the night before. No spreadsheet, no clipboard math.

1

Set your lineup

Add your players, with each one's main position and any backup spots.

2

Pick your league

Choose your league's rule, set the innings, and pin the pitcher and catcher you already know.

3

Print it or run it

Print a dugout sheet, or let the app move players to their spots each inning during the game.

📏 Your league's mandatory-play rule

Every player gets their minimum — and you know it before the first pitch.

  • Little League — every player gets at least 6 defensive outs (2 innings) and an at-bat
  • PONY, Cal Ripken, Babe Ruth — common local defaults, since each local league sets its own rule
  • Club / USSSA — no rule, just balanced bench time
  • Custom — set the minimum innings, how long anyone can sit, and infield time
  • A green ✓ Meets mandatory play, or a list of exactly who falls short

🧢 Fair, and baseball-smart

  • Pin your pitchers and catchers by inning — the app fills in everyone else
  • Nobody sits two innings in a row (a common local rule you can turn off with Custom)
  • Option: everyone gets at least one infield inning
  • Keeps players in their main position most, then their backup spots
  • Option: only play kids in positions you've listed
  • See each player's innings in the field, in the infield, and on the bench

📲 From the sheet to the field

  • Print it or save it as a PDF for the dugout
  • Turn on "use this rotation in the game" and players move to their spots each inning
  • Change anyone on the fly from the Defense screen
  • Share your lineup with your scorekeeper by QR — the rotation comes with it

Questions coaches ask

Does it work with 4 outfielders?

Yes. Turn on the 4-outfielder alignment for the game and the rotation uses all four spots.

What if I have too few players for the rule?

The app tells you who falls short and why — add an inning or adjust, and it rebuilds right away.

Our league's rule is stricter than Little League's.

Use Custom to set your own minimum innings, how long a player can sit, and infield time. Always check your league's rules.

Spend game day coaching, not doing math
