Pitch Tracking

Pitch counts & rest days, automated

Log pitch counts after each game and rest days calculate automatically. See at a glance who's eligible to pitch, who's on mandatory rest, and who's approaching their limit — even across multiple teams. Ineligible pitchers are flagged before you make the lineup.

How it works

Step 1

Add your roster

Enter your players, jersey numbers, and preferred positions. Takes about 2 minutes for a full team.

Step 2

Set your rules

Toggle on the rules your league enforces — minimum play, bench limits, pitching restrictions. Or skip and add them later.

Step 3

Build your lineup

Drag players onto the diamond or let auto-generate do it for you. Print the lineup card and head to the field.

Frequently asked questions

What sports does this work for?

Baseball and softball at any level — Little League, travel ball, rec leagues, high school, and adult leagues. The rules engine is fully configurable per team.

How does the free trial work?

You get 30 days of full access with no credit card required. Your data stays safe even after the trial ends — you just can't create new lineups until you subscribe.

Can parents see the lineup?

Yes. Parents get read-only access scoped to their linked player. They can see their child's position assignments, innings played, and pitch counts — but can't modify anything.

How are pitch counts tracked across teams?

Each team tracks their own pitch counts. For players on multiple teams, parents can report external pitch counts directly — so coaches don't have to chase down numbers from other teams. The rest day calculator considers every game automatically, not just yours.

What does "auto-generate" actually do?

It builds a complete lineup that satisfies all your enabled rules — minimum play, bench limits, infield requirements, pitching restrictions — while optimizing for fairness across the season.

Can I use this on my phone at the field?

Absolutely. The app is fully responsive and works on phones, tablets, and laptops. Add it to your home screen for a native app feel.

I already use a spreadsheet — why switch?

Spreadsheets don't track fairness across a season, calculate rest days automatically, or warn you when a player can't pitch. Who's on Second does all of that plus generates printable lineup cards. Most coaches switch in under 5 minutes — just enter your roster and go.

I'm not very tech-savvy. Is this easy to use?

If you can use a phone, you can use Who's on Second. Drag a player's name onto a position — that's it. No formulas, no complicated menus. Try the demo with zero commitment to see for yourself.

What happens to my data if I cancel?

Your rosters, games, and lineup history stay safe. You just can't create new lineups until you resubscribe. We never delete your data.

Do assistant coaches need their own subscription?

No. Your subscription covers the entire team. Invite unlimited assistant coaches, scorekeepers, and parents at no extra cost.

No ads. No data selling. Ever.

You pay a fair price, we build a great product. Your team's data belongs to you — we will never monetize it with ads or sell it to third parties.

Stop juggling spreadsheets

Build your first lineup in under 5 minutes. Import your roster, set your rules, drag players onto the diamond.
