More than a lineup card.

Who’s on Second builds a fair, rule-compliant lineup in minutes. Then it handles the pitch counts, the schedule, the snack rotation, and everything else that used to live in three different group texts.

    Try the rules builder
  3. Know who can pitch

The details

Build the lineup

Official rule sets, pre-loaded

Pick Little League, your NFHS state association, USSSA, USA Softball, or Cal Ripken/Babe Ruth, and the limits fill in for you. Pitch Smart guidelines are there too.

Age-appropriate setups

Turn off the pitcher or catcher for coach-pitch and tee-ball, or play four outfielders. The lineup follows how your league actually plays.

Fair playing time

Innings and positions balance across the whole season. Mark a player as arriving late and their share adjusts.

Lineup version history

Every save is kept. Roll back to any of the last 25 versions in one click.

On game day

Track the game

External pitch counts

Pitched for a travel team on Saturday? A parent logs the outing, and rest days count it.

Live scorekeeping and stats

Enter each plate appearance as it happens, and AVG, OBP, and SLG add up on every player’s profile. Import a GameChanger game and pitching lines like ERA and WHIP come with it.

Battery pairings

Rank the catchers each pitcher works best with. When that pitcher takes the mound, the top available catcher goes behind the plate.

Less typing, less texting

Share and sync

QR code lineup sharing

Parents get the full lineup. The other team’s scorekeeper gets the batting order only. Both work as a QR code or a link.

GameChanger import

Already keep score in the GameChanger app? Bring over your roster, then a game’s stats and pitch counts from its CSV or box score export.

Calendar sync

Paste your schedule feed once. Your games come in with a click, and a resync picks up anything that changed.

Snack duty

Families take turns, absent players get skipped, and the reminder emails go out without you.
