Little League Lineup: How to Build Fair Lineups for Rec Baseball

Nobody warned me lineups would be the hard part

I signed up to coach my kid's Little League team thinking the challenge would be teaching Aiden to stop throwing sidearm or convincing Caleb that he does, in fact, need to run to first base after he hits the ball. That stuff is fun. What nobody told me about was the Sunday night lineup panic.

It's 9:45 PM, the game is tomorrow at 6, and I'm hunched over my laptop with a half-eaten bowl of cereal trying to remember whether it was Jayden or Marcus who sat out the 3rd inning last Thursday. My wife walks by and asks why I'm more stressed about a 10U baseball game than I am about my actual job. Honestly? Fair question.

Rec ball lineup math is quietly brutal. I've got 13 kids on my roster, 9 spots on the field, and 6 innings to work with. That means I'm benching 4 kids every single inning. Over a 16-game season, that's hundreds of individual decisions — and Sophia's mom is absolutely keeping a mental tally of every single one. I promise you she is.

First thing: figure out your league's actual rules

I almost got myself in trouble my first season because I assumed all Little League organizations run the same playing time minimums. They don't. Our league president had to pull me aside after game two. Embarrassing. So before you do anything else, dig up your league's specific rulebook. Most land somewhere around these requirements:

• Every kid gets at least 6 consecutive defensive outs (2 innings) — not 6 total outs, consecutive
• Everyone bats at least once per game, even if they're benched for defense
• Some leagues require 3 full innings minimum — ours does, and I didn't know until week two
• All-star or tournament games sometimes have completely different rules, so read the fine print
• Mess this up and you could forfeit the game or get yourself suspended, which is a fun conversation to have with 13 families

But really, just meeting the minimum is a low bar. If a kid's only getting 2 innings a game in rec ball, they're basically standing around in a uniform. I try to get everyone to at least 70-80% playing time over the course of a season. That's hard to track in your head, which is why a playing time tracker is worth its weight in gold.

How I actually build a lineup these days

1. Get position preferences out of everyone's heads and into writing

First week of the season, before we even play a game, I send home a simple form. Where does your kid want to play? Where do they absolutely not want to play? I've learned to ask the kids directly too, because parents and kids don't always agree. Caleb's dad was convinced Caleb should pitch. Caleb just wanted to play second base. Caleb was right.

Get all of that into a lineup generator before the first game. Otherwise it lives in your head and your head is already full of pitch count rules and which kid is allergic to bee stings.

2. Figure out who sits and when — and spread it around

With 13 kids and 9 spots, somebody's sitting every inning. That's just life. The question is whether the same kids are always the ones sitting. I try to keep it so nobody sits more than 2 innings in any game, and I never sit the same kid in back-to-back innings if I can help it.

Sitting out the 1st and 4th innings feels totally different from sitting out the 5th and 6th. One kid gets to come back into the game feeling fresh. The other one finishes the game on the bench. Even if it's the same number of innings, parents notice the difference. Trust me on this.

3. Stop doing the position puzzle by hand

I wasted most of my first season trying to manually juggle all of this. 13 kids, 9 positions, 6 innings, position preferences, who sat out last game, who's been stuck in right field for three weeks. That's not coaching. That's a word problem from a math textbook. Let a lineup generator do the combinatorics while you worry about whether Aiden finally figured out how to field a grounder without closing his eyes.

4. Rotate the batting order — no kid bats last three weeks straight

Simplest trick I ever picked up: shift your batting order by one spot every game. Whoever led off Tuesday bats second on Thursday. By mid-season, every kid has hit in every spot. No arguments about who "always bats last," no parents doing batting order forensics. It's simple and it works.

5. Sanity check the numbers before you leave the house

Takes me two minutes before each game. I pull up the season stats and scan for anyone who's fallen behind. Maybe Emma missed two games for a family cruise and her playing time percentage tanked — so she's getting 5 innings today. Maybe Jayden hasn't touched the infield since that game three weeks ago. I'd rather catch it now than after Jayden's dad catches me in the parking lot.

Position rotation without losing your mind

Everyone wants shortstop, nobody wants right field

I had 7 kids list shortstop as their number one position. Seven. And exactly zero kids asked for right field. That's what you're working with. The temptation is to just put your best athlete at short and park the newer kids in the outfield all season. I did that my first year. It was a mistake.

Track infield vs. outfield innings across the season. Even the kid who's still learning to catch a fly ball deserves some time at second base. Put them there in the 1st inning when nobody's keeping score yet and the pressure is low. That's how they get better. That's literally the entire point of rec ball. If we just wanted to win, we'd play the same 6 kids every inning and bench everybody else.

Pitcher and catcher are a whole different situation

You can't rotate pitcher and catcher the way you rotate the other 7 positions. Pitch counts, mandatory rest days between appearances, and honestly the safety factor with catching — not every kid is ready to take a bat-speed foul tip off the mask. I've got about 4 kids who can pitch and 2 who are comfortable behind the plate. I rotate within those groups and focus everyone else on the other 7 spots.

Plan three games at a time, not one

I used to agonize over making every individual game perfectly balanced. That's a recipe for going crazy, especially when you've got the rained-out makeup game on a Thursday when half your team can't make it. Now I think in 3-game chunks. Over any stretch of three games, every kid should get some infield time, some outfield time, and their fair share of bench innings. Nobody's going to complain about sitting 2 innings on Thursday if they played all 6 on Saturday. It's the season totals that matter, not any single game.

The real-world chaos of rec ball

"He's played outfield the last three games"

You're going to get this one. Marcus's mom corners you by the dugout after the game. She's got that look. "Marcus has been in the outfield for three straight games. When is he going to play shortstop?" And honestly, sometimes she's right. You did let Marcus slip through the cracks. But sometimes she's remembering it wrong — Marcus played third base two innings last Tuesday, she just wasn't watching that inning because she was in the concession stand line.

This is where having actual data saves you. You pull up the numbers, show her Marcus's position breakdown for the last five games, and the conversation changes completely. She either goes "oh, I didn't realize" or you see a genuine gap you need to fix. Either way, it's a conversation, not an argument.

The kid who's been playing travel ball since age 5 and the kid who signed up yesterday

Welcome to rec ball, where the skill range on any given team is roughly the width of the Grand Canyon. You've got Sophia fielding backhand grounders like she was born doing it, and you've got Tyler who put his glove on the wrong hand at the first practice. They're on the same team. They both deserve to play.

You obviously can't throw Tyler at shortstop in the bottom of the 6th when you're clinging to a one-run lead. But you can put him there in the 1st inning of a game where you're not playing the league's best team. Or in the 4th when you're up by 8. Pick your spots. Development and competition aren't enemies — you just can't always do both at the exact same moment.

Half the team missing because it's spring break / picture day / raining

Rec ball rosters are unreliable and I say that with love. Disney World, soccer tournaments, someone's grandma's birthday, the kid who "forgot it was a game day" — I've heard every excuse. Last season I had a game where only 8 kids showed up, and one of them had a cast on. You just roll with it. Build your lineup with whoever's there. The kids who showed up get extra innings. A decent fairness tracker adjusts for missed games automatically, so nobody gets penalized for being reliable.

Frequently asked questions

What are Little League minimum playing time rules?

Standard Little League rules say 6 consecutive defensive outs (that's 2 innings) and at least 1 at-bat per game. But your local league might be stricter — ours requires 3 innings. I found this out the hard way. Look it up in your league's rulebook before you play your first game, not your third.

How do you make a Little League lineup fair?

Track everything across the whole season, not game by game. Rotate positions so everyone gets infield and outfield time. Shift the batting order each game. And use a tool to track it all because I can tell you from experience that doing it in your head stops working around game four.

How many innings should each player play in Little League?

In a 6-inning game, I shoot for 3-4 innings per kid as a floor, not a target. Over the season, everyone should land in the 70-80% range. If someone's consistently below that — maybe they missed a couple games, maybe they just slipped through the cracks — bump them up in the next few games to even it out.

Can you use a lineup generator for Little League?

That's basically what saved my sanity. Lineup Hero was built for exactly this situation — you set up your roster, mark everyone's position preferences, and it spits out a fair lineup for each game based on the full season's data. I still tweak things manually, but it handles the 90% of the work that was eating my Sunday nights.
