Boston Red Sox pitcher Aroldis Chapman continues to throw fastballs that register 100 mph [1] on the radar gun.
This level of performance is rare for a veteran pitcher. Maintaining such velocity into the late stages of a career challenges the typical biological decline associated with professional athletics.
Chapman is now 37 years old [2]. Despite his age, he has maintained a reputation as a power pitcher by routinely reaching the 100 mph mark [1] for 16 years [3].
His ability to deliver high-velocity pitches remains a central part of his utility for the Boston Red Sox in Massachusetts. The consistency of his arm speed over nearly two decades places him in a unique category of pitchers who can sustain peak physical output long after their peers have slowed down.
While most pitchers see a significant drop in fastball velocity as they enter their late 30s, Chapman has defied that trend. His longevity is rooted in a career-long commitment to power pitching, and precision.
The radar gun continues to validate his status as one of the hardest throwers in the league. By keeping his fastball at 100 mph [1], Chapman remains a formidable opponent for hitters regardless of his tenure in the sport.
“Aroldis Chapman continues to throw fastballs that register 100 mph”
Chapman's ability to sustain 100 mph velocity at 37 years old serves as a statistical outlier in professional baseball. Most pitchers experience a decline in arm speed due to age and wear, but Chapman's 16-year streak of elite speed suggests a rare physiological durability that extends the viable window for power-reliant relief pitchers.
