Diamond Data PRO turns your batting order from a hunch into arithmetic.

Enter each hitter's on-base percentage and slugging percentage. The app evaluates the batting orders your roster can actually produce and returns the one with the highest projected run total — then explains, slot by slot, why each hitter landed where they did.

WHY THE ORDER MATTERS

A batting order is a sequence, and sequences multiply. Nine hitters can be arranged 362,880 ways. Twelve can be arranged 479,001,600 ways. Every one of those orders produces a different expected run total, because who bats in front of whom decides how often your best hitters come up with runners on base.

"Best average third, power fourth, weakest bat ninth" is a rule of thumb from an era when nobody could check it. Diamond Data PRO checks it.

BUILT ON STATS YOU ALREADY HAVE

No pitch-by-pitch charting. No season of data collection before you get an answer. If you know each hitter's OBP and SLG, you can optimize today. OPS is shown for reference so you can sanity-check a roster at a glance.

FREE AND PRO

Start with the preloaded sample team and create one team of your own at no cost. Pro adds unlimited teams, sync across devices and saved lineups. Current subscription pricing is shown in the app before you are charged.

NO SPREADSHEETS

No spreadsheet formulas, no desktop software, no season of data entry before the app is useful. Pregame planning that fits in the time a coach actually has.

WHO IT IS FOR

Baseball and softball coaches, youth through high school. Travel, rec and school teams. Built for the coach who is also cutting the grass and running the fundraiser.

WHAT IT WILL NOT DO

It will not invent offense that is not in your numbers, and it will not promise you a win. A projection is an expected value across many games; a single game is dominated by opposing pitching, defense and luck. What it does is stop you giving away runs to a sequencing decision made out of habit.

You also know things the numbers do not — a player back from injury, a kid who isn't ready to bat leadoff, a developmental reason to move someone up. Every slot can be overridden, and the projection updates so you can see the trade.
