Pitching From the Stretch vs Windup — Which Is Best for Kids?
The debate coaches and parents have on every youth travel ball field. Here's what the data says, what elite pitching coaches recommend, and why modern baseball is trending toward one clear answer.Quick Answer
For youth pitchers: start with the stretch — master it before adding the windup.
The stretch is simpler, easier to repeat, and is the delivery that matters most when runners are on base. MLB data shows no meaningful velocity difference between the two. Elite pitching coaches Tom House and Ron Wolforth both advocate teaching the stretch exclusively before introducing the windup. There is no rule requiring a pitcher to use the windup with the bases empty — it's always a choice.
The Quick Breakdown — Windup vs Stretch
The Windup
Used with bases empty (usually)
Advantages
More momentum and longer stride — can help with velocity
More time for the pitcher to gather and focus
High leg kick aids rhythm and hip drive
Builds confidence and intimidation factor
Traditional pitching motion seen in MLB
Disadvantages
More moving parts — harder to repeat consistently
Slower delivery — gives baserunners more time to steal
Young pitchers often struggle with the footwork
Can't be used as effectively with runners on
The Stretch
Used with runners on (and increasingly without)
Advantages
Simpler motion — easier to learn and repeat
Faster delivery — holds runners, prevents steals
More deceptive — disrupts hitter's timing
Can be used in any situation — bases empty or loaded
Modern MLB trend: many starters stretch-only
Disadvantages
Less time to gather — can be harder mentally for nervous pitchers
Slide step can sacrifice velocity if done incorrectly
Less opportunity for the full hip drive of a high leg kick
What the Data Actually Says — Does the Windup Throw Harder?
One of the most persistent myths in youth baseball coaching is that pitchers throw harder from the windup than the stretch. It's intuitive — the windup has more movement, a bigger leg kick, more momentum building before release. It seems like it should generate more velocity.
The data says otherwise. A velocity study of MLB pitchers shows no statistically meaningful difference in pitch speed between windup and stretch deliveries. Fastballs thrown from the windup clock at essentially the same velocity as those thrown from the stretch. This has been replicated across multiple analyses at both the professional and amateur levels.
Why the windup doesn't add velocity
The momentum generated in the windup is largely offset by the additional time required to transfer that momentum into the delivery. The stretch is a more direct, efficient path to the release point — what it lacks in buildup it compensates for in directness. For young pitchers who are still developing their mechanics, the extra movement of the windup often creates inconsistency that reduces velocity rather than increasing it. A pitcher who can't repeat their windup consistently is throwing at inconsistent velocity from one pitch to the next.
What Elite Pitching Coaches Actually Recommend
Here's what the coaches who specialize in youth pitching development actually recommend:
| Coach / Source | Recommendation | Reasoning |
|---|---|---|
| Tom House (National Pitching Association) | Stretch exclusively first | Simpler mechanics allow young pitchers to focus on the fundamentals that actually matter — hip drive, stride length, arm path — without managing extra movement |
| Ron Wolforth (Texas Baseball Ranch) | Stretch exclusively first | The stretch is the more important delivery — it's what pitchers use in every critical high-leverage situation. Master it before adding complexity |
| Modern MLB trend | Many starters stretch-only | Multiple MLB starters across the last decade have switched to stretch-only delivery to simplify their mechanics. The FanGraphs analysis "Decline of the Windup" documented this growing trend — no velocity loss was found in any case |
| Traditional coaching | Windup with bases empty | Historical convention — the windup "looks right" for a starting pitcher and maintains separation of the two deliveries. Still common at high school and college level |
No rule requires the windup with bases empty
This surprises most parents and even some coaches: there is no rule in MLB, high school, or youth baseball requiring a pitcher to use the windup when the bases are empty. It's entirely the pitcher's choice. Plenty of MLB starters pitch exclusively from the stretch all game regardless of base situation — it's a growing trend as analytics have confirmed the velocity equivalence and highlighted the mechanical repeatability advantage of the simpler delivery. For youth pitchers, this matters: if a player is comfortable and effective from the stretch, there is no reason to force the windup on them.
The Little League and Youth Baseball Rule You Need to Know
For 8U–12U Little League and youth leagues: the stretch has less value than you think
In Little League baseball and most youth leagues at the younger age groups, runners cannot leave the base until the ball crosses the plate. This eliminates the entire strategic reason for using the stretch — there are no stolen base threats to worry about. For these age groups, the choice between windup and stretch is purely about mechanical comfort and consistency. If a pitcher is more comfortable and mechanically cleaner from the stretch, use it. If the windup produces better mechanics and rhythm, use that. The urgency of "you must learn the stretch to hold runners" doesn't apply until players reach the age group where stealing is permitted.
Pitching From the Windup — Step by Step
The windup begins with the pitcher facing home plate with both feet on the rubber. For right-handed pitchers:
| Step | What Happens | Key Point |
|---|---|---|
| Set position | Both feet on rubber, chest facing batter, ball in glove | Weight is balanced — not leaning forward or back |
| Rocker step | Small step back or to the side with the non-pivot foot | 4–6 inches — this is the key extra movement the windup adds. Keep it small and consistent |
| Pivot | Pivot foot turns to be parallel and flush against the rubber | Pivot foot fully against the rubber is critical for maximum push-off |
| Leg lift | Front knee lifts to balance point — knee above hip | Balance point is the pause between gathering and exploding toward the plate |
| Drive and stride | Explosive stride toward home plate, hip rotation leads the arm | Hips open before the throwing arm — hip drive, not arm strength, generates velocity |
| Release and follow-through | Ball released over front foot, arm follows through down toward opposite knee | Finish low — high finish means the ball will run high in the zone |
Pitching From the Stretch — Step by Step
The stretch begins with the pitcher standing sideways on the rubber — for right-handed pitchers, chest facing third base. This is the fundamental difference in starting position.
| Step | What Happens | Key Point |
|---|---|---|
| Set position | Pivot foot against the rubber, glove side shoulder pointing toward home plate | Right-handed pitchers face third base. Left-handed pitchers face first base |
| Coming set | Hands come together in front of the body, brief pause | The pause must be complete — a rolling start is a balk. Brief but definite stop |
| Check runners (optional) | Look toward the base before delivering or making a pickoff move | Only possible from the stretch — not from the windup |
| Leg lift or slide step | Front knee lifts toward balance point (full kick) or a quick reduced step (slide step) | Full kick = more power. Slide step = faster delivery, holds runners better |
| Drive and stride | Explosive stride toward home, hip rotation leads arm | Identical to windup from this point — the difference is only in the setup |
| Release and follow-through | Same finish as windup — arm down toward opposite knee | Once the leg lift starts, mechanics are identical to the windup |
Windup vs stretch mechanics comparison
The Slide Step — What It Is and When to Use It
The slide step is a modified version of the stretch delivery used specifically when a runner is likely to steal. Instead of a full leg kick to the balance point, the pitcher takes a quick reduced lift and immediately drives toward home plate — reducing delivery time by 0.2–0.4 seconds, which is often the difference between a stolen base and a caught stealing.
The trade-off is real: the slide step sacrifices some hip drive and can reduce velocity by 2–4 mph compared to a full leg kick from the stretch. For most youth pitchers, the slide step is not necessary until they're at an age and level where runners are actually stealing with realistic success. Teaching the slide step too early can ingrain a habit of short-arming the delivery that creates mechanical problems.

When to Use Each Delivery — By Situation
| Situation | Use | Why |
|---|---|---|
| Bases empty (any level) | Windup or stretch — pitcher's choice | No strategic advantage for either. Use whatever produces the most consistent mechanics |
| Runner on first | Stretch | Need to hold the runner and deliver quickly to prevent steal attempts |
| Runner on second only | Stretch or windup — varies by pitcher | Steal risk is lower from second than first — many pitchers use windup here. Depends on runner's speed |
| Runner on third only | Windup or stretch | Steal of home is extremely rare — most pitchers use windup here freely |
| Runners on first and second | Stretch | Multiple steal threats — quick delivery essential |
| Bases loaded | Stretch or windup — varies | No steal risk (force plays at any base), some pitchers return to windup |
| Youth leagues with no stealing (8U–10U) | Either — based on mechanical comfort | No stolen base threat — pure mechanics decision |
Can You Balk From the Windup?
Yes — though it's rare. Most balks occur from the stretch position because that's where the rules are more complex. From the windup with runners on base, once a pitcher begins a natural motion associated with their delivery, they are committed to delivering the pitch. Any stoppage, hesitation, or attempted pickoff after the motion begins is a balk. This is why most pitchers switch to the stretch with runners on — the stretch has clearer rules for what constitutes a legal pickoff attempt versus a balk.
The 2013 third-to-first rule change
Before 2013, pitchers could fake a throw to third base and then spin to throw to first — a legal deception move. As of 2013 in MLB, this "third-to-first" move is a balk. If a pitcher fakes or throws to third, they cannot then throw to first without first stepping off the rubber. This rule change is relevant specifically for stretch delivery situations with runners on multiple bases.
What This Means for Your Player — By Age Group
| Age Group | Recommendation | Key Focus |
|---|---|---|
| 8U–10U (no stealing) | Either — lean toward stretch for simplicity | Mechanics only — no baserunning strategy needed. The simpler motion helps young pitchers focus on arm path and stride |
| 10U–12U (stealing begins) | Stretch as primary, introduce windup | Start developing stretch competency now. Windup can be learned but stretch should be the priority |
| 13U–14U travel ball | Both — situation dependent | At this level the distinction matters competitively. Pitcher should be proficient from both and know when to use each |
| High school | Both — windup with empty bases standard | Traditional expectation at this level. College coaches often expect to see both deliveries. Pitchers who stretch-only may face pushback from traditional coaches |
Frequently Asked Questions
Should youth pitchers use the stretch or windup?
For most youth pitchers, start with the stretch. It's simpler, easier to repeat, and is the delivery that matters most in high-leverage situations when runners are on base. Elite pitching coaches including Tom House and Ron Wolforth both recommend teaching the stretch exclusively before introducing the windup. Once a pitcher has solid stretch mechanics, adding the windup is straightforward because the delivery from the leg lift onward is identical.
Do pitchers throw harder from the windup or the stretch?
MLB data shows no meaningful difference in pitch velocity between the windup and stretch. Fastballs clock at essentially the same speed from both deliveries. The intuition that the windup generates more power is not supported by velocity data — the additional movement in the windup doesn't translate to higher release velocity.
When should you pitch from the stretch?
The stretch is required when there's a runner on first base or runners on first and second — any situation where a stolen base is a realistic threat. The faster delivery from the stretch gives the catcher more time to throw out a stealing runner. Many pitchers also use the stretch with no runners on base as a matter of preference, and there's no rule preventing this.
Can a pitcher use the stretch with no runners on base?
Yes — there is no rule requiring the windup with bases empty. It's entirely the pitcher's choice. Many MLB pitchers pitch exclusively from the stretch regardless of the base situation, finding the simpler motion easier to repeat consistently. If your pitcher is more effective and consistent from the stretch with bases empty, let them use it.
What is a slide step in pitching?
A slide step is a modified stretch delivery where the pitcher skips the full leg kick and instead takes a quick reduced lift before driving toward home plate. It reduces delivery time by 0.2–0.4 seconds and is used specifically to prevent stolen bases. The trade-off is reduced velocity (2–4 mph) because less hip drive is generated. Youth pitchers generally don't need the slide step until they're at an age where runners are stealing frequently.
Can you balk from the windup?
Yes — though it's uncommon. With runners on base and pitching from the windup, once you begin a natural motion associated with your delivery, you are committed to delivering the pitch. Stopping, hesitating, or attempting a pickoff after the motion begins is a balk. This is why most pitchers switch to the stretch with runners on — the stretch rules for pickoff attempts are clearer and better defined.
Which is better for youth baseball — stretch or windup?
The stretch is generally better for youth development because it's simpler to learn, easier to repeat, and is the more important delivery in competitive situations. For very young players in leagues where runners can't steal (8U–10U), the choice is purely mechanical — use whichever produces better form. At 12U and above where stealing matters, stretch competency becomes essential and should be the priority.
The bottom line
The stretch is the more important delivery — master it first. The windup doesn't add velocity (the data is clear on this), it adds complexity. For young pitchers still developing their mechanics, complexity is the enemy of consistency. Start from the stretch, build clean repeatable mechanics, and add the windup once the foundation is solid.
The one caveat: at the high school level and above, traditional expectations and some coaches will push for the windup with bases empty. Know that there's no rule requiring it and no velocity benefit — but understand the cultural context your player is pitching in.
