You volunteered to coach your kid's baseball team. You bought the bucket of balls, watched a few YouTube videos on fielding drills, and showed up ready to go. But then came the part nobody warned you about: building the lineup.
Most youth coaches make the same handful of mistakes when it comes to lineups. The good news? They're all easy to fix once you know what to look for.
Mistake #1: The Same Kids Always Play Infield
It's tempting to put your strongest players at shortstop and first base every game. They make the plays, the team wins more, and nobody complains - right?
Wrong. The kids stuck in outfield notice. Their parents definitely notice. And those outfield kids never get the reps they need to actually improve at infield positions.
The fix: Rotate every player through both infield and outfield positions across the season. At the rec level, development matters more than wins. A rotation system ensures every kid gets meaningful time at every position group.
Mistake #2: Not Tracking History Game to Game
You build a great lineup for Game 1. Then Game 2 rolls around and you start from scratch. By Game 5, you have no idea who's played where - and a parent approaches you with a very specific list of innings their kid has spent in right field.
The fix: Keep a running record of every player's position history across games. When you build next week's lineup, reference last week's. Tools that track history automatically make this painless.
Mistake #3: Uneven Bench Rotation
With 13 players and 9 positions, someone has to sit each inning. The mistake is letting the same kids absorb most of the bench time - usually the less vocal ones whose parents don't push back.
The fix: Bench time should be distributed evenly. No player sits twice before every player has sat once. Track it just like you track positions. If a player sat two innings last game, they shouldn't sit at all this game.
Mistake #4: Last-Minute Lineup Scrambles
Two kids text that they can't make it. Now your carefully planned lineup has holes. You're frantically rearranging in the dugout while the ump is asking if you're ready, and the result is a mess that's anything but fair.
The fix: Build your lineup system so it can handle absences gracefully. If you're doing it manually, have a plan for how to redistribute positions when the roster shrinks. Or use a generator that adjusts automatically - enter the players who showed up, and let it figure out the rest.
Mistake #5: Ignoring Position Preferences Entirely
There are two extremes here. Some coaches let every kid play wherever they want (chaos). Others ignore preferences completely and force every kid through every position regardless of ability or safety.
Neither works. A 7-year-old who's never caught before shouldn't be behind the plate in a game without practice. But a kid who "doesn't want to play outfield" still needs outfield reps.
The fix: Set honest position preferences based on ability and safety - not desire. Mark which players can pitch and catch (positions that require specific skills), and let everyone rotate through everything else. Preferences should be guardrails, not a wish list.
The Common Thread
All five of these mistakes come down to the same root cause: not having a system. When lineups are built on gut feel and memory, unfairness creeps in - even with the best intentions.
The solution is simple: track positions, track history, rotate evenly, and plan ahead. Whether you do that with a spreadsheet or a tool like Inning Wizard, having a system is what separates the coaches who get thank-you emails from the ones who get parking lot confrontations.
Your players signed up to play. Make sure they all get to.
