⚾ Hitting (Left-Handed)
🧠
Left-Handed Advantage at the Plate
As a left-handed hitter, Harrison has a natural advantage in youth baseball: he's a step closer to first base and faces predominantly right-handed pitchers — meaning inside fastballs break toward his power zone. Teach him to recognize that advantage and hunt pitches on the inner half to pull.
🔄
The Proper Load — Anti-Wrap (LH)
Same principle as right-handers but mirrored. In the load, the bat knob should point toward the catcher, with the barrel NOT wrapping behind the head. A string tied to the barrel gives instant feedback. For lefties the string should stay visible on the left side of the helmet at load — not fly back toward third base.
🦵
Drive Off the Back Leg (Left Side)
For LHH, the RIGHT leg is the back leg. Harrison must drive and explode off that right side — not pivot and "squish the bug." Place a bucket outside the right foot: a powerful swing drives the foot toward the pitcher; pivoting in place knocks the bucket. Elite lefties (like Dave Ortiz, Barry Bonds) drive through, not rotate in place.
Launch Position Timing
Now facing kid pitchers with varying speeds, Harrison must get to his launch position early. Early Hover Drill and Foot Strike Drill train the habit of loading before the pitch arrives — not reacting to it. Most swing breakdowns at this age happen because the hitter is late setting up. Load early, decide late.

The LHP Advantage: Controlling the Running Game
Left-handed pitchers naturally face first base in their set position — giving them a massive pick-off advantage that right-handers don't have. Harrison should learn to vary his look to first base (hold the ball 1–3 seconds randomly before pitching or throwing over) to keep runners honest. This is a weapon unique to lefties.
💪
Fastball Mechanics for Young LHP
For a 9-year-old LHP: start with the 4-seam fastball grip only. Focus on arm path coming through the hip (not dropping or flying out), snapping the wrist through the release, and following through across the body to protect the elbow. No breaking balls yet — wrist/elbow development is the priority. Velocity comes from hip drive, not arm speed.
📐
Wind-Up & Set Position
In the wind-up: big leg kick drives down the mound and toward home, finishing with the glove-side foot landing closed (toward first base for a lefty). In the set: small, controlled knee lift to maintain balance. For AAA ball, a consistent repeatable delivery matters far more than top velocity — coaches notice a kid who throws strikes.
🏃
Pitcher's Fielding Practice (PFP)
After every pitch, Harrison must land in a fielding position — glove up, feet shoulder-width, ready to react. At 9U this is often neglected but it's a huge differentiator. The most common PFP plays: comebacker to the mound (field and throw to first), covering first base on ground balls to the right side, covering home on wild pitches.
🥊 First Base Fielding
🥊
The 1B Stretch — Left-Hander's Natural Fit
Left-handed first basemen have a natural advantage: their glove hand faces the infield, making catches and scoops easier on throws from the left side. The key technique: catch the ball first, THEN find the bag with the foot — not the other way around. Left foot on the inside corner of the bag, stretch as far as needed toward the throw.
🤲
Scooping Short Hops at First
The most important skill for a 1B at this age: scooping bad throws. Teaching points: eyes on the ball all the way into the glove, soft hands (give with the glove), and stay low. Practice short-hop drills against a wall or with a partner — 10–15 short-hop catches per session builds confidence and saves a lot of errors.
👣
1B Footwork on Ground Balls
When fielding a ground ball himself, Harrison must get in front of it (don't glove-side reach), field cleanly, and either tag the bag or toss underhand to the pitcher covering. Common mistake: turning the wrong way after fielding. Lefties at 1B should catch, turn right (toward home plate side), and look for the play.
🌞 Right Field
🌞
First Step: Read the Ball Off the Bat
The #1 skill for outfielders at any level. Harrison should be in an athletic stance, weight slightly forward on balls of feet, as the pitcher releases. Watch the bat angle and ball flight for the first 0.5 seconds to determine direction and depth. First step MUST be definitive — hesitation is the enemy. Drill: partner hits off tee, Harrison reads and breaks immediately.
🦅
Crow Hop Throw from RF
The crow hop is how outfielders generate arm strength on throws. After catching, gather momentum: small skip/hop toward the target, plant the right foot (back foot for a lefty thrower), and drive through the throw. Even at 9U, practicing proper crow hop mechanics means Harrison will throw with far more velocity and accuracy than kids who throw flat-footed.
📣
Communication in the Outfield
Teach Harrison to call "I got it! I got it!" loudly on every ball he's going for. Right fielder takes priority over center fielder who takes priority over left fielder (and all outfielders over infielders in their territory). Calling the ball and being decisive prevents collisions and shows the team leadership — coaches notice this every time.
👁 Don't Strike Out Looking
👁
The Called Third Strike Is the One You Control
A strikeout swinging means you competed. A strikeout looking means the pitcher beat you without you even trying. At AAA level, most close pitches get called strikes — so a hitter who takes close ones often hands the at-bat away. Harrison's approach needs to flip: look to attack, not look to take. Two strikes = attack mode, no exceptions.
Commit the Stride Early — Decide Late
Striking out looking is almost always a timing and decision problem, not a mechanics problem. The fix: start the stride as the pitcher's arm comes forward, not after you've decided to swing. For LHH Harrison, the right foot (front foot) should be lifting and beginning to stride as the pitch is released — this keeps him in "attack ready" rather than "watch and decide." Load early. Decide at the last half-second. The stride is not a commitment to swing — it's a commitment to be ready.
🎯
Two-Strike Approach: Protect the Plate
With two strikes, the approach changes completely. Choke up 1–2 inches on the bat for more control. Widen the stance slightly for better balance. And most importantly: swing at anything close. The zone expands with two strikes — borderline pitches that were "balls" earlier become too risky to take. The mental cue is simple: "Two strikes — if it's close, it's mine." At youth level, umpires typically tighten the zone on the hitter with two strikes, so leaning aggressive is almost always right.
🧠
Know the Zone Before the At-Bat Starts
Before stepping in, Harrison should watch at least 2–3 pitches from the on-deck circle and ask: How hard is this pitcher throwing? Where is he locating? What is the umpire calling? If the ump is calling high strikes, know it and adjust. If the pitcher is wild early but hits the zone late in the count, know it. Information gathering before the at-bat starts is the difference between a guessing hitter and a prepared hitter. Never step in blind.
💡
Pick a Zone, Hunt a Pitch
An unfocused hitter "waits to see something good" — and often watches a strike go by because it wasn't perfect. A focused hitter picks a zone: "I'm looking for a pitch middle-in, belt-high." If it's there, attack it. If not, take. For Harrison as a LHH, his power zone is middle-to-inside — pitches he can pull or drive to the left-center gap. Going to the plate with a specific look stops the passive watching that leads to called third strikes. The drill: before every simulated at-bat, make Harrison say out loud what pitch/location he's hunting.
🏆 Mindset & Development
🏆
The Coach Posada Philosophy
Jorge Posada was known for toughness, preparation, and a relentless competitive fire. But behind all of that was an enormous amount of work on fundamentals. At Harrison's age, the goal is simple: fall in love with the process of getting better. Celebrate improvement over results. Effort and attitude are the only two things Harrison controls 100% of the time.
📅
Session Structure for Harrison
Recommended 45-min session: 5 min warm-up / light throw, 10 min hitting drills (1–2 focused drills), 10 min pitching or fielding work (alternate each session), 15 min live hitting or simulated at-bats, 5 min cool-down + one specific praise and one coaching point. Keep it fun and high-energy every time.

⚾ Batting — Left-Handed Hitter
🔄
Bat Load — Anti-Wrap Check (LH)
At load, the bat knob should point toward the catcher. The barrel stays above your left shoulder. A wrapped bat (barrel past the head toward 3rd base) makes your swing long and slow.
❌ WRAPPED
WRAP ↓ catcher Long slow swing
✓ CORRECT LOAD
✓ HERE knob Short fast swing
💡 String test: Tie a string to the barrel. At load it should stay on the left side of your helmet — if it flies toward 3rd base, that's a wrap!
🦷
Back Foot Drive — Don't Squish the Bug
Your right foot (back foot for LHH) powers the swing. After contact, it should DRIVE forward toward the pitcher — not spin in place. Spinning = leaving power behind.
SQUISH THE BUG DRIVE FORWARD spins in place — no power! ← PITCHER drives toward pitcher — full power!
💡 Bucket drill: Place a bucket just outside your right foot. Your swing should push the foot forward toward the pitcher — not spin around the bucket.
🔥 Pitching — Left-Handed
🌌
Pitching Delivery — 4 Checkpoints
Every pitch should hit all 4 positions. Consistent delivery = strike-thrower. Coaches notice the pitchers who throw strikes more than the ones who throw hard.
