How Fast Can the Average Person Throw a Baseball?

Eric DawsonByEric Dawson Sports

For “how fast can the average person throw a baseball,” there is no research-backed average for untrained adults. Throwing speed varies widely with experience, physical development, mechanics, age and the type of throw. One 26-year-old Reddit user reported a 60 mph maximum in a stadium pitch game, but that self-reported result is not a population average.

Organized-player benchmarks provide context, not an answer for casual adults: 10- and 11-year-olds are listed at 44-54 mph, 16-year-olds at 73-78 mph, and average 17-year-old pitchers in the upper 70s to low 80s. Elite pitchers are a separate category, with Division I fastballs averaging 89.2 mph and MLB four-seam fastballs exceeding 94 mph by 2023.

How Fast Can the Average Person Throw a Baseball?

A single number would be misleading because the available evidence does not use a validated population-wide dataset or a shared testing method for casual adult throwers. That means an easy catch, a full-effort overhand throw, a radar-game attempt, and a mound pitch are not interchangeable measures of throwing velocity.

Studies involving trained baseball players cannot answer the question for the average person because those athletes have substantial throwing experience. Neither can a ball-flight conversion chart, which translates velocity into travel time rather than measuring how hard a particular person throws. One biomechanics study discussed in the available evidence involved 20 male subjects with substantial throwing backgrounds, not a representative sample of untrained adults.

Forum anecdotes can show the range of individual experience, but they cannot establish a population average.

Why a Simple Average Does Not Work

Context changes the meaning of every reading. Pitch speed is typically measured from a mound with a full pitching motion, while a casual throw may come from flat ground, an unfamiliar stance, or a shortened windup. Radar games add another setting, with their own conditions and measurement approach.

Organized baseball benchmarks are also built around players who practice throwing, often play a specific position, and develop physically at different rates. Developmental age, which describes physical maturity relative to calendar age, can matter more than birthday age for young pitchers.

For adults, prior baseball background may create an especially wide spread in results. Age alone cannot explain how fast adults throw, since a person who has pitched or played regularly brings a different movement pattern and throwing history than someone who rarely throws a baseball.

Professional and college fastball numbers are even less useful as stand-ins for ordinary adults because those pitchers are selected specialists and the four-seam fastball is generally their fastest pitch. Meaningful comparisons need to identify the throw, setting, effort level, and the person’s playing experience before attaching much value to any mph reading.

Why Throwing Speed Varies so Much

A full-effort pitch is not interchangeable with every other kind of throw, so average baseball pitch speed and general throwing speed describe different contexts.

Developmental age matters more than a player’s birthday age, because it reflects how physically developed that player is. Earlier puberty and physical development can mean more muscle mass, leverage, strength, and running speed, allowing a player to throw harder than a smaller, later-developing peer of the same age.

For example, Professional Baseball Strength describes a 5’11”, 150-pound 13-year-old as physically more developed than a 5’3″, 100-pound teammate, with consequences for running, jumping, throwing, and hitting. Growth also does not produce steady gains: velocity can jump during a growth spurt, plateau when mechanics break down, or fall after injury.

Experience changes the picture. Trained baseball throwers have substantial throwing experience, which is why their results cannot stand in for people without that background. Mechanics and physical readiness are necessary for improvement, but gains cannot be rushed. Rather than treating velocity as an annual schedule, players should expect uneven progress: high-school and college pitchers may gain 5-6 mph in a year when they grow 4-5 inches, add 15-20 pounds, and improve mechanics, while gains may be smaller or nonexistent.

Pitching context adds a layer. A pitcher is assessed through the fastest pitch normally thrown, the four-seam fastball, while a throw may occur in a different setting. Field dimensions also change as youth players advance: moving from 12U to 13U shifts from 70-foot bases and a 50-foot mound to 80-foot bases and a 54-foot mound.

At 14, players first use a 60/90-foot field, with the mound 60’6″ from home plate. Comparisons across those stages therefore need more than an age label or radar reading.

Skill level further separates organized pitchers from elite specialists. College recruiting generally calls for 87-95 mph in Division I, 85+ mph in Division II, and 82+ mph in Division III and junior college, while professional power pitchers may regularly exceed 100 mph.

Goals therefore extend beyond how to throw a baseball faster. Command matters because high velocity without control can lead to more walks, hit batters, and wild pitches. Strength development supports coordination, efficiency, fatigue reduction, and accuracy, while mechanics and physical readiness support improvement.

Average Throwing Speed by Age and Skill Level

Organized-player benchmarks offer a useful average throwing speed by age, but they describe pitchers rather than every child or adult who throws a baseball. At ages 10 and 11, the suggested pitching range is 44 to 54 mph; by the late teen years, typical velocities reach the upper 70s and low 80s.

Among 8- and 9-year-olds, online-posted ranges run from 36 to 42 mph and 37 to 50 mph, respectively, though the emphasis at those ages is learning to throw and catch and enjoying the game. For 10- and 11-year-old players, 44 to 54 mph is the suggested range, and most hitters in that group would not make contact at that speed.

During ages 12 and 13, early developers typically throw 57 to 61 mph, advanced 13-year-olds often reach 61 to 64 mph, and late developers fall below 55 mph at 12 or below 60 mph at 13.

Fourteen-year-olds typically throw 65 to 69 mph, with a goal of reaching the 70s by year’s end. On the 60/90 field first used at age 14, the mound sits 60 feet 6 inches from home plate, while bases are 90 feet apart. Freshmen around age 15 commonly throw 69 to 77 mph; players who approach or reach 80 mph, locate the fastball and throw an off-speed strike may have a chance to make JV or varsity. Sixteen-year-olds average 73 to 78 mph.

Age Group Organized-Player Benchmark Pitching Context
Ages 8-9 36-42 mph to 37-50 mph Early youth baseball
Ages 10-11 44-54 mph Organized youth players
Ages 12-13 Under 55 mph to 64 mph Late developers through advanced 13-year-olds
Age 14 65-69 mph First season on a 60/90 field
Age 15 69-77 mph Freshman baseball
Age 16 73-78 mph Organized high-school-age players
Age 17 Upper 70s to low 80s High-school-age pitchers
Age 18 Mid-to-upper 70s Older high-school-age pitchers

High-school benchmarks continue upward. Seventeen-year-olds typically average upper 70s to low 80s, while larger, more physically mature players can reach 85 to 87 mph. Eighteen-year-olds mostly throw in the mid-to-upper 70s; larger players throw 81 to 84 mph, and fully developed players can reach the upper 80s to lower 90s.

Left-handed pitchers typically throw 2 to 3 mph slower than right-handed pitchers at all levels. These figures are organized-baseball pitching benchmarks, so they should not be read as an average baseball pitch speed for all adults.

College baseball illustrates how sharply throwing velocity by skill level separates selected pitchers from youth and high-school ranges. Division I fastballs average 89.2 mph, while LSU and Tennessee average 94.4 mph and 93.4 mph, respectively.

Meanwhile, high-school guidance also emphasizes fastball location and an off-speed strike.

Instead of treating every number as a target, use the table to place a pitching result alongside the relevant age group and level of organized play. At 16, a 76 mph average and 3 mph standard deviation put 34% at 79 mph, 13% at 82 mph, and 2% at 87 mph in the example.

How Fast Can Adults Throw Compared with Pitchers?

For a baseball, the earlier limitation still applies. Casual throws, stadium radar-game attempts, and trained pitches from a mound are different measurements, so their readings should not be treated as interchangeable. Context determines what the reading actually describes. Speed alone does not identify the task.

Pitching is a specialized baseball action, rather than a catch-all measure of how fast adults throw. TopVelocity’s evidence review also rejects unsupported online ranges as a basis for an adult average.

Radar-game results add another complication. Because a Chicago White Sox stadium pitch game reported by a 26-year-old Reddit user and another throwing context need not match, the result cannot stand in for how fast adults throw generally. It is useful only as an individual maximum in that particular game, under the user’s reported circumstances.

Method matters because there is no shared standardized protocol here for comparing a casual overhand throw, a mound pitch, a radar-game attempt, and a full-effort baseball pitch. Ball-flight conversion charts do not solve that problem: they give equivalent travel times rather than measure a person’s throwing velocity. That difference means one setting’s number cannot automatically answer how hard someone would throw in another. Neither an equivalent flight time nor a single radar reading supplies a common definition for every kind of baseball throw.

Trained pitchers are also a selected group, not a stand-in for adults as a whole. Velo University reports an average Division I fastball velocity of 89.2 mph, while Major League Baseball’s average four-seam fastball exceeded 94 mph by 2023. Major League figures describe professional specialists.

Placed alongside a casual throw, these are elite pitching figures rather than an average adult benchmark. For a useful comparison, keep the setting consistent: compare a radar-game reading with another radar-game reading, or a mound pitch with another mound pitch.

What Elite Baseball Velocity Really Means

Elite velocity describes performance within selected baseball populations, not a normal benchmark for adults or even most organized players. College recruiting thresholds and Major League fastball averages reflect pitchers in selected higher-level college and professional baseball competition settings.

At the college level, those recruiting thresholds provide context. Those figures are recruiting context, rather than an average baseball pitch speed for everyone who plays college baseball.

Velo University reports an average Division I fastball velocity of 89.2 mph. Its figures for LSU and Tennessee, 94.4 mph and 93.4 mph respectively, show how far top programs can sit above that Division I average. Such numbers describe elite selected teams, not the velocity a person needs to enjoy baseball or develop as a player.

Major League Baseball sits farther still from ordinary comparison. In 2008, the average MLB four-seam fastball was below 92 mph; by 2015 it had surpassed 93 mph, and by 2023 it exceeded 94 mph. Meanwhile, the regular-season count of fastballs above 100 mph rose from 214 in 2008 to 3,848 in 2023. Aroldis Chapman’s MLB-recognized 105.8 mph four-seam fastball, thrown on September 24, 2010, marks a record elite pitch rather than a useful target.

Rather than treating professional radar readings as a personal standard, judge throwing velocity by skill level, control, mechanics and physical readiness. Control remains essential. Similarly, its college-coaching example says adding 1-2 mph to a pitcher who can already pitch may be easier than teaching a 90 mph thrower how to pitch. Better goals pair any pursuit of more speed with strength, efficient mechanics, accuracy and command.

For perspective, these are outcomes from specialists at the sport’s highest level. Because those outcomes come from specialists at the sport’s highest level, they set the outer edge of performance, not a baseline for average adult throwing ability in baseball today.

How to Throw a Baseball Faster Without Chasing Numbers

Prioritize sound mechanics, physical readiness and command before treating radar readings as the goal. Better velocity can follow growth, strength development and improved mechanics, but progress does not arrive on a fixed timetable.

Begin with an approach that treats throwing velocity by skill level as a result of preparation, not the only test of a useful throw. Professional Baseball Strength identifies good mechanics and physical readiness as necessary for improvement, while Velo University describes strength development as support for coordination, efficiency, fatigue reduction and accuracy.

  1. Establish a repeatable throwing motion and use command as part of the standard.
  2. Build physical readiness through strength development that supports coordination, efficiency, fatigue reduction and accuracy.
  3. Review progress over time rather than assuming a player will gain 3 to 4 mph every year.

Age and physical development should shape the target, especially for youth players. Developmental age reflects how physically developed a player is relative to chronological age, and earlier puberty can bring greater muscle mass, leverage, strength and running speed. Consequently, players of the same birthday age may not be ready for the same velocity expectation.

Rather than making a radar result the sole measure, evaluate location, the ability to throw an off-speed pitch for a strike, and the capacity to pitch effectively. College coaching advice cited by Professional Baseball Strength suggests it may be easier to add 1 to 2 mph to a pitcher who can already pitch than to teach a 90 mph thrower how to pitch.

For adults, order applies: work on mechanics and physical readiness, then judge each effort by velocity and control. Avoid reading an organized-pitcher range as every adult’s typical throwing speed, because those ranges describe players at ages and stages of development. Instead, use throws, accurate location and reduced fatigue as signs that training is supporting throwing.

Velo University says research has not proven velocity to be a cause of injury at any level, while presenting an experience-based view that younger players who throw harder face injury risk. Sensible expectations keep the focus on building a throw that works, not producing a radar number.

Frequently Asked Questions

What Throwing Speed Is Typical for an Untrained Adult?

No research-backed average has been established for the general, untrained adult population. Studies of trained throwers do not represent casual adult throwers, and unsupported online ranges cannot supply a reliable population estimate.

What Is the Average Throwing Speed by Age in Organized Baseball?

Organized-player benchmarks rise with age and physical development: 10- and 11-year-olds are suggested at 44-54 mph, 14-year-olds typically throw 65-69 mph, and 16-year-olds average 73-78 mph. Seventeen-year-olds typically average the upper 70s to low 80s, although developmental age, growth, mechanics and injury history can create major differences among players of the same chronological age.

How Fast Can Adults Throw a Baseball Without Pitching Experience?

A reliable general number is not established because available information does not provide a standardized comparison of casual throws, mound pitches, radar-game attempts and full-effort pitches. One Reddit user, age 26, reported a 60 mph maximum at a Chicago White Sox stadium pitch game, but that self-reported result describes one person rather than an adult average.

What Throwing Velocity Do College Baseball Programs Look For?

Professional Baseball Strength says college recruiting generally calls for 87-95 mph at Division I, 85 mph or more at Division II, and 82 mph or more at Division III and junior college. Velo University reports an average Division I fastball velocity of 89.2 mph, while LSU and Tennessee average 94.4 mph and 93.4 mph, respectively.

Can Better Mechanics Help a Player Throw a Baseball Faster?

Good mechanics and physical readiness are necessary for velocity improvement, although gains do not follow a fixed schedule. Players can make large jumps during growth spurts and after improving mechanics, while mechanical breakdowns can cause velocity plateaus.

Throwing speed has no single meaningful answer for the average person because research-backed data for untrained adults has not been established. Organized baseball figures offer context, but they describe players shaped by age, development, training and pitching experience. A hard fastball also is only part of pitching: strength, mechanics, control, location and the ability to throw off-speed pitches all matter. Elite college and Major League velocities should not be used as a baseline for casual adult throwing.
