A command bullpen is a short, scripted session that puts target work ahead of velocity or pitch design, starting with a four-seam layup line and moving through a planned 20 or 30 pitch script. The structure comes from ABCA protocols, and the workload rules come from MLB’s Pitch Smart guidelines. Run both together and you get a session that builds strikes instead of just arm speed.
TL;DR:
- Fastball command improves most quickly when the pitcher focuses on consistent mechanics during the layup line before targeting specific zones.
- Adding off-speed pitches should only occur after fastball control and accuracy are reliably established across all target zones.
- A pitcher’s hit rate—landing four to six out of six throws in a zone—is a better indicator of readiness than velocity or radar readings.
- Workload limits for youth pitchers follow age-based pitch counts and rest days, with bullpen intensity kept low until most throws are in the target zones.
- Using visual feedback tools like strike-zone nets and tracking hit rates helps pitchers develop accuracy efficiently outside of live game environments.

Building the bullpen progression from warm-up to advanced zones
A command bullpen works because it moves the pitcher through stages, not straight into max effort. Jumping into hard throws without a ramp is how command disappears and fatigue shows up early.
The sequence coaches should run looks like this:
- Activation: five to eight minutes of dynamic movement, band work, and light long toss to raise arm temperature without taxing it.
- Layup line: 8 to 12 four-seam fastballs thrown at a middle target, focused purely on repeating the same arm path and release point.
- Zone work: once the layup line is consistent, shift to glove-side, arm-side, high, and low spots, one zone at a time.
- Advance: add a second pitch or situational count only after the fastball zones are landing at a reliable rate.
This order matters because early reps establish a repeatable delivery before the pitcher starts aiming for corners. A pitcher who skips the layup line tends to chase location with arm manipulation instead of trusting the same mechanics each time, which is exactly what ABCA’s structured bullpen piece is built to prevent.
Fastball command drills coaches can run today
Command improves fastest when the target is small and the feedback is instant. A flat strike zone gives a pitcher nothing to aim at; a nine-zone grid or a plate-sized patch gives them something concrete to chase.
A few drills that hold up across skill levels:
- Layup-line drill: middle-middle only, four-seam grip, focused on a clean release.
- Wall-target drill: a taped or painted spot at shoulder height for pitchers working on release consistency between sessions.
- Partner point drill: a catcher or coach points to a zone before the pitch, simulating in-game target changes.
- Rhythm reps: three pitches thrown back to back with no pause, training tempo instead of overthinking each throw.
Structure sets as four to six reps per spot with short rests between sets, not between pitches. Success is a hit rate, not a radar reading: a pitcher landing 4 of 6 in a zone is ready to advance, and one landing 2 of 6 needs more reps there before moving on. A strike-zone net with marked zones speeds up this feedback loop because the pitcher sees the result instantly instead of waiting on a coach’s call.
Pro Tip: Track hit rate by zone on a simple tally sheet. A number on paper tells a pitcher more than a coach’s gut feeling.
Sequencing pitches: when and how to add off-speed
Off-speed pitches only belong in the bullpen once fastball command is consistent, meaning the pitcher is hitting target zones at a steady rate across a full set. Adding a changeup or breaking ball before that point just teaches two inconsistent pitches instead of one reliable one.
A simple way to build a script:
- Open with 6 to 8 four-seam fastballs to middle and corner zones from the stretch.
- Add 4 to 6 fastballs from the windup, repeating the same zones.
- Introduce 4 to 6 changeups or breaking balls, thrown only to zones already mastered with the fastball.
- Close with 2 to 4 mixed pitches simulating a two-strike or full-count situation.
Avoid stacking three or more off-speed pitches back to back. Thrown in a row, they build a slower, looser arm action that can bleed into the fastball delivery. ABCA’s pitch scripts approach recommends scripting the full session ahead of time so a coach is not deciding pitch mix on the fly.
Turning Pitch Smart into bullpen-specific rules
Bullpen pitches count toward a pitcher’s daily total, so Pitch Smart limits apply here just as much as they do in games. The guidelines set age-based daily maximums and required rest days tied to pitch totals, and they place responsibility on parents and organizations to track workload across every team a player appears on, not just one league.
Pitch Smart’s daily limits scale with age, for example 75 pitches for 9 and 10 year olds and 95 for 13 and 14 year olds, with required rest days increasing as the pitch total climbs, according to MLB’s Pitch Smart guidelines.
Keep bullpen intensity submaximal for most of the session, reserving full effort for a handful of pitches at the end if at all. A simple rule: cap bullpen pitches at roughly half the age-appropriate daily maximum pitch count, and count every bullpen throw toward the week’s total. For more detail on scaling workload by age, see this breakdown of pitch count limits. Watch for dropped velocity, altered arm slot, or a sudden loss of command mid-session: these are signs to stop, not to push through.
Letting catchers call pitches and adding game pressure
A bullpen only transfers to games when it feels like one. Letting the catcher call pitches within simple limits trains pitch selection, not just arm mechanics.
- Set basic count rules before the session starts, such as a reliable pitch on 0-0 and a chase pitch allowed on 0-2.
- Simulate pressure with a batter standing in, or by naming a runner on base before a set begins.
- Let the pitcher and catcher work through a shaky sequence before stepping in, saving mechanical corrections for between sets.
This kind of collaborative pitch-calling is common in practice for 13 and 14 year olds, according to ABCA’s coaching notes on youth pitching development, and it reduces the urge to micromanage every throw.
Two scripts you can run in practice this week
A 20-pitch script works well for relievers or shorter outings, emphasizing quick readiness from the stretch:
- 4 four-seam fastballs from the stretch, middle target.
- 4 fastballs from the stretch, glove-side and arm-side corners.
- 6 fastballs mixing high and low zones, stretch only.
- 4 off-speed pitches to zones already hit consistently.
- 2 pitches simulating a full count finish.
A 30-pitch script suits starters, building fastball command before adding a second pitch:
- 8 fastballs from the windup, middle and corner targets.
- 6 fastballs from the stretch, repeating the same zones.
- 6 changeups or breaking balls to mastered zones.
- 6 mixed pitches alternating fastball and off-speed by count.
- 4 pitches simulating two-strike and ahead-in-count situations.
Advance to the next stage only when the pitcher is landing most throws in the intended zone with a clean arm path. Stop early if fatigue, pain, or a sudden mechanical change shows up, regardless of how many pitches remain on the script. For a full walkthrough of pacing a session like this, this step-by-step bullpen routine breaks down each phase in more detail.
Coaching notes on building command safely
Command bullpens work best when a coach treats every rep as data, not just repetition. Watching for a consistent release point matters more than counting strikes alone, since a pitcher can land a pitch in the zone with a flawed delivery that will not hold up over a season.
A pitcher who repeats his delivery will find the zone. A pitcher who chases the zone will lose his delivery.
Pro Tip: Set a pitching target net at a fixed distance and height for every session so the only variable that changes is the pitcher’s execution, not the setup.
A simple checklist helps: set the target before the first throw, track hit rate by zone during the session, and compare that rate week over week rather than session over session. A portable strike-zone net makes this easy to replicate at home or on the field without needing a full catching setup.
Why patience with command pays off later
Chasing velocity before command is the most common shortcut I see in youth pitching, and it rarely holds up. A pitcher who can hit a spot with a fastball before he can throw hard is building a skill that lasts; a pitcher who throws hard before he can locate is building a habit that is tough to unlearn.
Command-first development also tends to protect arms, since it keeps intensity lower while the real skill, repeatable mechanics, gets built first.

Training aids that make these drills easier to run
A strike-zone target net turns the layup line and zone drills into something a pitcher can run solo, since the feedback is visible the moment the ball hits the mesh. The Pitching Target Net with Colorful Strike 9-Zone sets up fast in a yard or driveway, which matters for getting in the extra reps that build command between team practices.
For at-home repetition without the risk of a hard ball near a house or garage, a soft pitch training baseball kit gives younger pitchers a safer way to log volume on the layup line and zone drills. Pair it with a batting-practice setup like the Pedal Baseball Launcher for situational reps against a live-looking target. Browse the full PITCH TRAINING BASEBALL KIT™ lineup in the primary collection to find the setup that fits your pitcher’s age and space.
FAQ
How fast should a 13 year old pitcher be throwing?
There is no single verified velocity standard for 13 year olds, and command matters more at this age than raw speed. Coaches following Pitch Smart guidelines focus on pitch counts and rest rather than velocity benchmarks for this age group.
What are the three F’s in baseball?
This is not a term defined in pitching or coaching guidelines referenced here, and the phrase is not standard in baseball coaching literature. Coaches are better served focusing on fundamentals like fastball command, finish, and footwork, which do appear consistently in structured bullpen guidance.
What is a good long toss program for a 14-year-old pitcher?
A safe long toss program builds distance gradually during the activation phase of a session, staying well below max effort. It should feed into, not replace, the structured command work covered in a bullpen routine built around pitch scripts and rest.
Why does nobody throw a screwball anymore?
The screwball has largely fallen out of use because it places unusual stress on the arm and shoulder compared to more common breaking pitches. Coaches today more often teach pitchers to control two or three reliable pitches for strikes, per ABCA’s coaching guidance, rather than add rare, high-stress pitches.
What is a command bullpen in youth baseball?
A command bullpen is a scripted practice session where a pitcher throws a set number of pitches to specific target zones, prioritizing accuracy over speed. It typically starts with four-seam fastballs to a middle target before progressing to corner and off-speed work, following ABCA’s structured bullpen format.
