Put a player at every position for every inning, in about a second. Then print the card and coach the game.
Youth baseball asks a volunteer to be fair to eleven families at once, before 8am, with a pen.
Every player needs infield time early. Nobody should sit twice while another kid never sits. Nobody should stand in right field all game. Holding all of that in your head, inning by inning, is the hard part.
You may not be counting innings on the bench, but somebody in the bleachers is. A card you can hand over ends the conversation before it starts.
One player is out, another arrives in the second inning, and the card you wrote at breakfast is wrong. Changing one spot should not mean starting over.
Innings run across the top and positions down the side, the way a card should read. Press Build lineup and every spot fills at once, following your league's rules.
Set the rule your league plays by, or turn it off. Build works to it either way.
Nobody sits twice before everyone sits once, and nobody sits two innings in a row.
Set the first inning or two by hand. Build fills the rest around them.
Move a player with your thumb. The list is the batting order, and it prints with the card.
One tap when a player misses a game. Build works around them, and around anyone who should not pitch, catch or sit.
