113 MPH Baseball Pitch: The Ultimate Fastball
A 113 mph baseball pitch would be the fastest pitch ever recorded in professional baseball history. It would exceed the current official MLB record (105.8 mph by Aroldis Chapman) by over 7 mph and approach the theoretical maximum pitching velocity possible for human athletes. At this extreme speed, a batter would have only about 375 milliseconds to react, making it virtually unhittable.
The Rarity and Significance of a 113 MPH Pitch
In the world of baseball, pitching velocity has always been a measure of dominance and a source of fascination. A 113 mph (181.9 km/h) fastball represents the absolute frontier of human athletic performance—a speed so extreme that it has never been officially recorded in professional baseball. To understand just how extraordinary this velocity is, we need to examine the current landscape of elite pitching speeds and records.
Current Velocity Records in Professional Baseball
The progression of pitch velocity records illustrates how a 113 mph pitch would shatter existing benchmarks:
| Pitcher | Speed (MPH) | Date | Context |
|---|---|---|---|
| Aroldis Chapman | 105.8 | Sept. 24, 2010 | MLB game (Reds vs. Padres) |
| Jordan Hicks | 105.1 | May 20, 2018 | MLB game (Cardinals vs. Phillies) |
| Ryan Helsley | 104.2 | Oct. 1, 2022 | MLB game (Cardinals vs. Pirates) |
| Jhoan Duran | 104.0 | June 16, 2023 | MLB game (Twins vs. Tigers) |
| Nolan Ryan (claimed) | 108.1 | Aug. 20, 1974 | MLB game (pre-radar gun era)* |
*Measured using primitive radar technology and later extrapolated—widely considered less reliable than modern measurements.
As shown in the table, even the legendary Nolan Ryan's disputed 108.1 mph pitch falls 5 mph short of the 113 mph threshold. Such a pitch would represent a quantum leap in pitching performance, comparable to breaking the 10-second barrier in the 100-meter dash or the 4-minute mile in track and field.
Distribution of Pitch Velocities in Modern Baseball
To contextualize how extraordinary a 113 mph pitch would be, consider the distribution of fastball velocities among MLB pitchers:
- Average MLB fastball (2023): 93.9 mph
- Top 1% of MLB fastballs: 99-100 mph
- Top 0.1% of MLB fastballs: 101-102 mph
- Top 0.01% of MLB fastballs: 103+ mph
- Pitches above 104 mph: Fewer than 100 recorded in MLB history
- Pitches above 105 mph: Fewer than 20 recorded in MLB history
A 113 mph pitch would surpass the average MLB fastball by nearly 20 mph and exceed even the most elite velocities by 8+ mph. This would place it beyond the current understanding of human physiological limits for baseball pitching.
The Physics and Biomechanics Behind a 113 MPH Pitch
Understanding the physics and biomechanics of a 113 mph pitch reveals why such velocities remain theoretical rather than regularly achieved. The perfect combination of physiological attributes, mechanical efficiency, and physical conditions would be required to approach this frontier.
Key Physical Factors in Generating Extreme Velocity
Several interconnected factors contribute to a pitcher's maximum velocity potential:
Biomechanical Components
- Kinetic chain efficiency: The sequential transfer of energy from legs through torso to arm
- Arm length: Longer limbs create greater angular velocity at release
- Shoulder external rotation: Greater rotation enables more energy storage
- Forward trunk tilt: Optimal positioning to maximize energy transfer
- Hip-shoulder separation: Creating torque through rotational differences
Physiological Requirements
- Fast-twitch muscle fiber ratio: Higher percentages enable explosive movements
- Tendon elasticity: Efficient storage and release of energy
- Joint integrity: Ability to withstand extreme forces without injury
- Neural recruitment: Activating maximum muscle fibers simultaneously
- Connective tissue strength: Supporting structures resistant to tearing
The Physics Equation of a 113 MPH Pitch
From a pure physics perspective, the velocity of a pitched baseball can be expressed through these key relationships:
- Energy transfer: The kinetic energy of a 5 oz baseball traveling at 113 mph is approximately 96 joules
- Force generation: To achieve this velocity, a pitcher must generate approximately 400-500 pounds of force
- Rotational mechanics: Shoulder internal rotation velocities would need to exceed 7,000 degrees per second
- Acceleration period: This extreme force must be applied over approximately 0.02 seconds during the acceleration phase
- Torque requirements: Elbow valgus torque would approach 120-130 Nm, near or exceeding the structural limits of the ulnar collateral ligament
These calculations reveal that a 113 mph pitch would likely push the human body to its absolute structural limits, explaining why such velocities remain theoretical even among elite pitchers with optimal mechanics.
The Injury Risk of Extreme Velocity
The forces required to generate a 113 mph pitch would create enormous stress on the throwing arm:
- UCL (Tommy John) threshold: Research suggests the ulnar collateral ligament begins to fail at forces lower than those required for 113 mph
- Shoulder capsule stress: Rotator cuff and labrum would experience forces exceeding typical injury thresholds
- Recovery capacity: Tissues would have minimal capability to recover from the extreme stress of such pitches
- Career longevity: Sustained pitching at near-maximal effort significantly increases injury risk and reduces career length
Batter Reaction Time and Hitting a 113 MPH Pitch
Perhaps the most intriguing aspect of a 113 mph pitch is the nearly impossible challenge it presents to hitters. The extreme velocity creates a reaction time scenario that pushes the limits of human neurological and muscular response capabilities.
The Reaction Time Breakdown
For a pitch traveling at 113 mph over the standard 60 feet, 6 inches from pitcher's mound to home plate:
| Stage | Time Required | Description |
|---|---|---|
| Total flight time | 375 milliseconds | Time from release point to crossing plate |
| Visual processing | ~100 milliseconds | Time needed for the brain to process what's been seen |
| Decision making | ~150 milliseconds | Time to decide whether to swing and where |
| Swing initiation | ~150 milliseconds | Time to physically execute the swing |
| Effective decision deadline | ~125 milliseconds | Point at which pitch has traveled ~2/3 to plate |
The crucial insight from this breakdown is that a batter must begin their swing before the ball has traveled even two-thirds of the way to home plate. This means decisions must be based on incomplete information about the pitch's ultimate location and movement.
Comparative Reaction Times by Pitch Speed
To understand the exponential difficulty increase with velocity:
| Pitch Speed (MPH) | Flight Time (ms) | Decision Deadline (ms) | Difficulty Level |
|---|---|---|---|
| 85 | 500 | 250 | Challenging but manageable |
| 95 | 447 | 197 | Very difficult |
| 100 | 425 | 175 | Elite professional level |
| 105 | 405 | 155 | Near human limits |
| 113 | 375 | 125 | Beyond reliable human capability |
As shown in the table, each incremental increase in velocity disproportionately decreases the already small margin for error. At 113 mph, the batter's decision deadline of 125 milliseconds falls below what neuroscience research indicates is possible for reliable, accurate responses.
The "Guess Hitting" Necessity
Against pitches approaching 113 mph, conventional reactive hitting becomes virtually impossible. Instead, batters would be forced to employ "guess hitting" strategies:
- Pre-pitch commitment: Deciding to swing before the pitch is even thrown
- Zone selectivity: Looking for pitches only in a specific area and ignoring others
- Pitch type anticipation: Expecting a specific pitch type based on counts and tendencies
- Timing shortcuts: Starting the swing early and adjusting mid-swing (rarely successful at extreme velocities)
Even with these approaches, consistent success against 113 mph pitches would be nearly impossible, explaining why even the hardest throwers in baseball history (105+ mph) have been extraordinarily difficult to hit when their pitches are in the strike zone.
The Evolution of Pitch Velocity in Baseball
Understanding how pitch velocities have evolved over baseball's history provides important context for considering whether a 113 mph pitch might someday become reality.
Historical Velocity Progression
While precise measurements weren't available in earlier eras, researchers have estimated velocity progression through various methods:
| Era | Estimated Top Velocities | Notable Pitchers |
|---|---|---|
| 1910s-1930s | 90-93 mph | Walter Johnson, Lefty Grove |
| 1940s-1950s | 93-96 mph | Bob Feller, Herb Score |
| 1960s-1970s | 96-100 mph | Nolan Ryan, J.R. Richard |
| 1980s-1990s | 98-102 mph | Randy Johnson, Rob Dibble |
| 2000s-2010s | 100-105 mph | Aroldis Chapman, Joel Zumaya |
| 2020s | 100-105+ mph | Jordan Hicks, Jhoan Duran |
This progression reveals several important patterns:
- Top velocities have increased roughly 10-15 mph over the past century
- The rate of increase has slowed significantly in recent decades
- Despite technological and training advances, the 105-106 mph threshold has remained relatively stable as the upper limit since Chapman's 2010 record
Factors Driving Velocity Increases
Several key developments have contributed to the steady increase in pitching velocities throughout baseball history:
Training and Development
- Biomechanical analysis: High-speed cameras and motion capture technology
- Weighted ball training: Specialized programs focusing on arm speed
- Strength training: Advanced lower body and core development
- Nutrition and recovery: Optimized physiological support systems
- Early specialization: Pitchers focusing on the craft from youth
Tactical and Strategic Shifts
- Specialized roles: Relievers throwing max effort for shorter durations
- Velocity prioritization: Scouting and development favoring raw speed
- Technology feedback: Instant velocity data influencing mechanics
- Incentivization: Financial rewards for power pitching
- Physiological selection: Taller, more explosive athletes recruited
Will We Ever See a 113 MPH Pitch in Professional Baseball?
Given the historical progression and current understanding of human physiology, several factors inform predictions about whether a 113 mph pitch might someday be achieved:
- Physiological limits: Research suggests the structural integrity of arm tissues may impose a practical ceiling around 106-108 mph
- Diminishing returns: The progression of record velocities has plateaued in recent decades despite advances in training
- Risk-reward balance: Pitching at absolute maximum effort significantly increases injury risk
- Game context: The most extreme velocities typically occur in specific contexts (first pitch, adrenaline spikes)
- Measurement technology: Advanced tracking systems like Statcast may provide more precise measurements than previous technologies
Most biomechanics experts and sports scientists consider 113 mph to be beyond what's physiologically possible without risking catastrophic arm injury. However, exceptional outliers in human performance have surprised us throughout sports history, leaving open the small possibility that a uniquely gifted athlete with perfect mechanics might someday approach this frontier.
How Pitchers Train to Increase Velocity
For pitchers aiming to reach their maximum velocity potential, specialized training approaches have evolved significantly in recent years. While a 113 mph pitch remains beyond current capabilities, these methods have helped pitchers push the boundaries of performance.
Modern Velocity Development Programs
Contemporary velocity training integrates multiple approaches:
- Mechanical efficiency training: Video analysis and motion capture to optimize kinetic chain sequencing
- Weighted ball protocols: Systematically varied weight implements to develop arm speed and strength
- Long toss progressions: Extended distance throwing to build arm strength and proper force application
- Plyometric training: Explosive movement patterns to develop fast-twitch fiber recruitment
- Connection exercises: Specialized drills focusing on linking lower body power to arm action
Leading pitching development centers like Driveline Baseball and the Texas Baseball Ranch have pioneered data-driven approaches that have helped numerous pitchers add 3-6 mph to their fastballs, though even these advanced methods haven't produced pitchers exceeding the ~105 mph threshold.
Physical Preparation for Maximum Velocity
The physical foundation required for extreme velocity includes several key components:
- Lower body power development: Squat variations, plyometrics, and medicine ball work
- Core and trunk stability: Anti-rotation exercises and dynamic stability training
- Shoulder preparation: Specific rotator cuff and scapular strengthening
- Mobility work: Emphasis on hip internal rotation, thoracic rotation, and shoulder external rotation
- Recovery protocols: Advanced modalities including cold therapy, compression, and active recovery
These physical preparation elements must be integrated with technical skill development for maximum effectiveness. No amount of strength training alone can produce elite velocity without corresponding mechanical efficiency.
Radar Gun Psychology: The Pursuit of Velocity
The psychological dimension of velocity development can't be overlooked. The "radar gun effect" has transformed how pitchers approach their craft:
- Immediate feedback loop: Instant velocity readings create rapid reinforcement cycles
- Competitive motivation: Pitchers challenging themselves and peers to reach new personal bests
- Identity formation: Many pitchers derive significant identity from their velocity readings
- Risk tolerance: The pursuit of maximum readings sometimes leads to elevated injury risk
- Career implications: Velocity thresholds often determine advancement opportunities and contract values
This psychological dimension explains why pitchers continue to pursue maximum velocity despite the increased injury risk. In professional baseball, even small velocity gains can translate to significant career opportunities and financial rewards.
Frequently Asked Questions About 113 MPH Pitches
Has anyone ever thrown a pitch at 113 mph in any context?
No, there is no verified record of any pitcher throwing a baseball at 113 mph in a professional game, practice, or training setting. The highest verified pitch velocity in MLB history is Aroldis Chapman's 105.8 mph fastball recorded in 2010. While there have been claims of higher velocities in non-game settings, none have been reliably documented reaching 113 mph using calibrated, modern tracking technology. Some training facilities have reported velocities approaching 108-109 mph using specialized weighted training balls (lighter than regulation baseballs), but these don't translate directly to game velocities with regulation balls.
How much harder is it to hit a 113 mph pitch compared to a 100 mph pitch?
Hitting a 113 mph pitch would be exponentially more difficult than hitting a 100 mph pitch. With a 100 mph fastball, a batter has approximately 425 milliseconds from release to crossing the plate, leaving about 175 milliseconds for decision-making. A 113 mph pitch reduces total flight time to about 375 milliseconds, with only about 125 milliseconds for decision-making—a 29% reduction in available decision time. This crosses the threshold of human neurological capabilities for reactive decisions. The difference might seem small in absolute terms (50 milliseconds), but it represents the difference between difficult but possible and virtually impossible for even elite hitters.
What physical characteristics would a pitcher need to throw 113 mph?
To hypothetically reach 113 mph, a pitcher would need an extraordinary combination of physical traits: exceptional height (likely 6'4" or taller) for leverage; above-average arm length for increased angular velocity; extremely high fast-twitch muscle fiber ratio for explosive movement; exceptional joint mobility, particularly in shoulder external rotation; superior connective tissue strength to withstand the forces involved; and optimal body proportions for mechanical efficiency. They would also need neurological capacity for perfect sequencing and remarkably elastic tendons for energy storage and release. This combination of traits would represent a truly rare physiological outlier, even among professional athletes.
Would a 113 mph pitcher dominate professional baseball?
Yes, a pitcher capable of consistently throwing 113 mph strikes would revolutionize baseball, assuming they could control the pitch and stay healthy. The near impossibility of hitting such a pitch would likely result in unprecedented strikeout rates above 75%. However, historical evidence suggests that as pitchers approach maximum velocity, command typically suffers. At 113 mph, even slight command issues would result in many walks and hit batters. Additionally, the extreme physical stress would likely prevent sustained performance, limiting innings and career longevity. The pitcher might dominate as a specialized reliever for a brief period before the physical toll became prohibitive.
Could future technology or training methods make 113 mph pitches possible?
Future advances might incrementally increase maximum pitch velocities, but 113 mph likely remains beyond sustainable human capability without medical intervention. Training innovations could potentially produce small gains through improved biomechanical efficiency, specialized strength development, and neurological training. However, the fundamental limiting factor appears to be the structural integrity of human connective tissues, particularly the ulnar collateral ligament and shoulder capsule. Without biological enhancements or modifications that strengthen these tissues—which would raise ethical and regulatory questions in professional sports—the 113 mph threshold will likely remain theoretical rather than regularly achievable.
