Coaching Positions: How I Read 12-Year-Olds Before They Know Themselves

Try-outs are not about talent

Every try-out season I remind myself of one thing: I am not selecting the best players. I am selecting the best trajectories.

At 12, a kid is halfway between chaos and potential. They do not know their position yet. They barely know what their own body is going to do when the ball comes off the bat. My job is to read the parts they cannot see.

The funny part is that most of what I use to place a kid on the field has nothing to do with how pretty their swing looks. The bat is loud and distracting. I pay more attention to how they move when nobody is watching them.

Station one: the walk to the field

The try-out starts in the parking lot. Or the bike rack, this being the Netherlands.

Watch how they walk up. Who carries their own gear. Who lets their parents carry the bag. Who shows up ten minutes early and starts playing catch with whoever is around, and who hangs back pretending to stretch while scanning for their friends.

I already have a rough map before we throw a single ball.

• The early worker. Usually ends up in the infield, often middle infield. They want the ball. They expect to be involved.
• The follower. Outfield or corner infield. Not bad. Just not yet ready to be in the blast radius of every play.
• The anxious perfectionist. Often becomes a pitcher or catcher if I can unhook the anxiety from the perfectionism.

I do not write this down. I just flag them in my head. Then I try to prove myself wrong during the drills.

How a kid warms up tells me everything

The warm-up is my favorite lie detector. Most kids think it is the boring part. The smart kids know that this is where coaches actually watch.

I look for three things while they throw and stretch.

• Attention to details. Do they line up with their partner? Do they adjust distance on their own? Do they care about hitting the chest, or is every throw a random launch?
• Tempo. Are they frantic, slow, or rhythmic? Frantic kids pull the ball all over the place. Slow kids often think more than they move. Rhythmic kids usually turn into strong defenders.
• Recovery. What happens after they miss? Laugh and reset? Spiral and apologize? Or silently correct their mechanics on the next throw?

The kid who misses arm-side, pauses, then quietly takes one extra warm-up crow hop while their partner is not looking, that kid is probably an infielder. Maybe a pitcher. They instinctively self-debug.

The kid who shrugs after air-mailing three in a row into the fence behind their partner? Outfield trial first. Let them move before we ask them to think.

Reading body language between reps

Try-out drills are noisy. Everyone yells. Parents coach from the fence. Kids peacock for their friends. I watch the in-between.

After a bad rep, where do their eyes go? Are they searching for my reaction? Parent reaction? Teammates? Or are they looking at the ground, replaying the movement in their head?

Eyes to the coach is a sign of approval-seeking. Not bad, just fragile short term. Eyes to the parent usually means external pressure. Eyes back to the spot where the ball was, then a small head tilt or self-correcting gesture, that is internal feedback wiring. You can build something around that.

I also look at the shoulders.

• Shoulders up by the ears. Lot of tension. Might throw hard in a bullpen, might implode in a real game.
• Shoulders loose but posture tall. Good candidate for the middle of the field. They can see the whole play without shrinking.
• Shoulders rolled forward, head down. I treat them gently. Often put them at second base or left field at first, then slowly test them with more responsibility.

How I decide who is an infielder

Everyone wants to be a shortstop. Especially the dads.

I do not care how hard a 12-year-old throws from deep short in a try-out. I care about how fast they decide. The internal clock is the whole story at this age.

Here is what I watch in the infield ground ball station.

• Pre-pitch routine. Are they frozen or bouncing on their toes as the ball enters the hitting zone?
• First step, not first throw. Do they read the hop early? Do they charge a slow roller or wait and trap it?
• Footwork near the ball. Do they dance around it to get their shoulders aligned, or just stab straight-legged and spin?

The kid who takes a tiny read step, then two quick adjustment steps so their chest ends up behind the ball, that is an infielder. Even if they throw like a trebuchet right now. I can fix an arm, I cannot manufacture that instinct easily.

A 12-year-old who already tracks the runner in their peripheral vision while fielding, then chooses not to throw because the runner is clearly safe, is gold. That is situational awareness under load. That kid goes to short or third, even if their metrics are merely average.

Outfielders: the kids who see the whole story

Most kids think outfield is a punishment. Stand in the grass. Swat mosquitos. Watch the infield have fun.

I disagree. Outfielders are my field generals in training. They make a hundred micro decisions per game that nobody tracks on paper.

Outfield try-out reads are subtle.

• First move on contact. Do they freeze, jump in, or drop step? The kid whose first move is back and then in usually learns faster.
• Line of travel. Do they curve their route to get behind the ball, or drift sideways and catch it perfectly parallel to the ground?
• Post-catch behavior. Where do they throw the ball instinctively? Straight to the coach, random cut-off, or the smart base?

I love the kid who overthrows the cut-off man but threw to the right base. Most coaches grumble about missed fundamentals. I see a developing game brain.

Shy kids often end up in the outfield by default. I test that. I put them in center for a drill and ask them to call the ball. Loud. Repeatedly. You can see in five reps if they are going to grow into that voice or hide from it.

Catchers: the weird ones who like chaos

Catchers at this age usually find themselves. You do not have to assign it. They are the kids who do not complain when the gear smells like old socks and wet dog.

During try-outs, I throw a couple of extra tests at potential catchers.

• How they receive. Are they stabbing at the ball, or can they calmly present a strike without snatching?
• Blocking instinct. When I bounce a ball in front of them, do they flinch away or fall forward and eat it?
• Communication. Do they talk to the pitcher, infield, or umpire at all, or do they sit in silence?

A 12-year-old who naturally turns to the umpire after a borderline pitch and just holds the ball for half a beat without being theatrical, that kid already understands one part of framing. They understand theatre, basically.

The emotional profile matters most here. Catchers see everything. They hear every parent comment. They feel every passed ball like a personal failure. If they cannot reset emotionally between pitches, I do not anchor them back there yet. I might love their arm and still put them at third for a year.

Pitchers: I care more about boredom tolerance

Pitcher try-outs are where parents lean in. Velocity. Mechanics. Strike percentage on ten throws. I barely look at the radar gun.

What I am mostly testing is boredom tolerance and emotional control.

• Between pitches. Do they rush the next throw to escape a bad one, or can they step off, breathe, and reset?
• Response to feedback. Can they process a tiny cue without trying to reinvent their entire delivery on the next pitch?
• Consistency across reps. Not outcome consistency. Movement consistency. Same leg lift, same arm slot, even when they miss badly.

If a kid throws 5 out of 10 strikes at 12 but looks exactly the same on pitch one and pitch ten, I mark them as a pitcher. If another kid throws 9 out of 10 but each pitch is a different science experiment, I hesitate.

The sneaky test I like: I deliberately talk to them about something unrelated between two pitches. School, favorite team, anything. If they can smile, answer, then step back on the rubber and deliver something that still looks like their last pitch, that is a kid I can trust under pressure.

Parents, pressure, and the hidden variables

I cannot talk about try-outs without talking about parents. They are part of the system, whether we like it or not.

I watch how a kid looks at their parent between stations. Just a quick glance, or constant scanning for approval? Heavy eye contact usually means heavy pressure at home.

That matters for position placement. A kid with a hyper-involved parent might technically be skilled enough for shortstop or catcher, but mentally they could be one mistake away from a full meltdown.

I sometimes put those kids at second base or right field to start, not as a demotion, but as a mental pressure valve. From there, I slowly move them toward the middle as they build their own internal voice.

People think positions are about ability. At 12, I think positions are about load management. Physical and emotional.

How honesty with kids actually works

I do not tell a 12-year-old, "you are an outfielder" as if that is carved into stone. I say, "you are an outfielder this season, because of how you move and see the game right now. That can change."

The phrasing matters. Most kids at this age are quietly trying to answer one question: "What kind of player am I?" If I hand them a rigid label, I box them in. If I hand them a temporary assignment with a clear reason, they usually run with it.

I also share the hidden things I saw during try-outs. I tell the skinny kid who barely hit the ball out of the infield, "I put you at short because you read hops better than anyone else here." Their whole posture changes. They know I saw them, not just their stat line.

What I get wrong every season

I misread kids every single year. That is part of the process.

The quiet kid in the corner suddenly becomes vocal once they feel safe. The flashy kid burns out after two weeks of actual practice. The presumed shortstop ends up loving the outfield because they finally have time to read the game without the ball screaming at their face every pitch.

So I treat my own judgments as strong hypotheses, not verdicts. The difference is how attached I am willing to be.

By mid-season, some roles flip. I had a kid last year who looked like a textbook corner outfielder in try-outs. Long stride, big arm, casual focus. Two months in, I realized he processed ground balls like a machine. Now he lives at third. My early read was not wrong, just incomplete.

The point is not to be right

Try-out season feels like sorting. But for 12-year-olds, it is closer to planting.

I am not trying to guess who they will be forever. I am trying to give them the position that matches their current nervous system, so they can actually enjoy the work long enough to become someone different.

Reading kids before they fully know themselves is not mystical. It is just paying attention to the moments everyone else ignores. The walk up. The missed throw. The eye contact. The breath after a mistake.

The rest is reps and time. And a little bit of dirt.
