Do Baseball Players Wear Cups?

It is one of the most common questions casual fans and youth-baseball parents ask: do baseball players actually wear protective cups? With baseballs flying around at 100 miles per hour and foul tips deflecting in every direction, it seems like an obvious yes, but the real answer is more nuanced and depends heavily on the position. So who wears a cup, who skips it, and what should a parent know before sending a kid onto the field?

The short version: cups are not required at the MLB level, but they are strongly recommended, and for some positions, like catcher, they are essential. Here is the full breakdown of who wears one, why, and the history behind this piece of protective gear.

The chart below covers cup usage by position, the history, and what parents should know. Take a look, then we’ll explain each part.

Cup usage by position
Who is most and least likely to wear one
Position Likely to Wear One? Why
Catcher Always Constant foul tips and balls in the dirt
Corner infield (1B, 3B) Often Hard-hit balls from a short distance
Middle infield (SS, 2B) Sometimes Bad hops on grounders
Pitcher About half Comfort issues with the leg kick
Outfield Less often Lower risk of a direct, close hit
Risk tracks with how close and how fast a ball is likely to arrive. The catcher, crouched right behind the plate, faces the highest risk and almost always wears one.
Why some MLB players skip the cup
Comfort: traditional cups can feel restrictive and cause chafing during a long game
Pitchers in particular find the cup uncomfortable during the high leg kick
Mobility: some players feel a cup slightly limits their range of motion
Risk tolerance: pros already accept facing 100 mph pitches, so some accept the odds
The tradeoff is real but risky. In 2018, Cardinals catcher Yadier Molina needed emergency surgery after a foul ball struck him in the groin, a reminder of why protection matters.
The history of the athletic cup
Year Milestone
1874 C.F. Bennett invents the jockstrap for Boston bicycle riders
~1900s Catcher Claude Berry adds a steel “safety cup” to his jockstrap
1920s The cup becomes standard gear across contact sports
1931 One of the first modern athletic-cup patents is filed
1970s Cups become far more commonplace and widely used
Today Hard plastic replaces steel; compression shorts hold the cup
Note: the 1874 invention was the jockstrap, not the cup. The protective cup came later, with early baseball use traced to catcher Claude Berry in the early 1900s. Exact dates vary by source.
For Parents and Players
What to know about youth baseball cups
Youth catchers are required to wear one
In Little League and most youth leagues, a cup is mandatory for catchers. For other positions it is strongly recommended, and many coaches require it for all players.
Compression shorts solve the comfort problem
Most players now use compression shorts with a built-in pocket for the cup instead of a traditional jockstrap. They are far more comfortable and stay in place better.

A properly fitted cup is comfortable and stays put when running or sliding. Youth and adult cups come in different sizes, so fit matters as much as the brand.

Do Baseball Players Wear Cups?

Yes, many baseball players wear protective cups, but it is not universal and it is not required at the MLB level. A cup is a hard protective shield, usually molded plastic, designed to protect a player from a direct hit by a baseball traveling at high speed. Whether a given player wears one comes down mostly to their position and personal comfort preference. The players most at risk, those who face hard-hit balls from close range, are the most likely to wear one, while players in lower-risk spots often go without. At the youth level, the calculus is different: cups are commonly required for catchers and strongly recommended for everyone else.

Cup Usage by Position

The likelihood of wearing a cup tracks closely with risk. Catchers almost always wear one, and for good reason: crouched directly behind the plate, they face constant foul tips and balls deflecting into the dirt right at them. Corner infielders at first and third base are the next most likely, since they field rockets hit from a short distance with little reaction time. Middle infielders at shortstop and second base wear them less consistently, mainly guarding against bad hops. Pitchers are split, only about half wear one, and outfielders are the least likely, since the ball rarely reaches them at close range with that kind of velocity. In short, the closer and faster the ball arrives, the more likely the player is to be protected.

Why Some Players Skip the Cup

Given the obvious risk, why would any player go without? The honest answer is comfort. Traditional cups can feel restrictive, cause chafing, and slightly limit mobility over a long game. Pitchers in particular often find a cup uncomfortable during their delivery, since the high leg kick can cause the cup to dig in or shift, which is a big reason only about half of them wear one.

There is also a risk-tolerance factor: professional players already accept stepping into the box against 100 mile-per-hour pitches, so some simply accept the odds. It is a real tradeoff, but the downside can be severe. In 2018, Cardinals catcher Yadier Molina took a foul ball to the groin and needed emergency surgery, a stark reminder of the stakes.

The History of the Athletic Cup

The protective cup’s story begins with the jockstrap, which was invented in 1874 by C.F. Bennett of a Chicago sporting goods company to support bicycle riders navigating Boston’s bumpy cobblestone streets. Importantly, that original invention was the supporter, not the cup.

The hard protective cup came later: baseball catcher Claude Berry is credited with one of the first uses, adding a steel “safety cup” to his gear in the early 1900s, since catchers had no groin protection at the time. By the 1920s the cup had become standard equipment across contact sports, one of the first modern cup patents was filed in 1931, and cups grew far more commonplace through the 1970s. The design has changed surprisingly little since, mostly swapping perforated steel for tough molded plastic.

What Sports Use Cups, and What They Are Made Of

Baseball is far from the only sport where cups are common. Hockey players almost universally wear them, given that pucks can fly well over 100 miles per hour. Football players typically start wearing them young because of the sport’s heavy contact.

Cricket, fencing, boxing, lacrosse, and mixed martial arts are other sports where cups are standard protective gear. Modern cups are made from high-density plastic with a padded edge, shaped to deflect impact while allowing airflow, and are rigorously impact-tested by manufacturers before sale. The technology has improved, but the core job, absorbing and spreading the force of a direct blow, has stayed the same for a century.

What Parents and Young Players Should Know

For parents getting a child into baseball, the guidance is straightforward. In Little League and most youth leagues, a cup is required for catchers and strongly recommended for every other position, and many coaches require it across the board.

The good news is that comfort is no longer the obstacle it once was: most young players now wear compression shorts with a built-in pocket that holds the cup securely, which is far more comfortable than the old jockstrap-and-cup setup and keeps everything in place while running or sliding. The key is fit, cups come in youth and adult sizes, so getting the right size matters as much as the brand. A properly fitted cup is something a young player will barely notice until the day it saves them from a painful injury.

The Bottom Line

So, do baseball players wear cups? Many do, but it is a personal choice at the professional level rather than a rule. Catchers almost always wear one, corner infielders frequently do, and pitchers are split roughly down the middle, while outfielders most often go without.

The decision comes down to balancing protection against comfort, a tradeoff that has gotten easier thanks to modern compression shorts and better cup designs. For young players, especially catchers, wearing a properly fitted cup is simply smart, low-cost insurance against one of the most painful injuries the game can deliver.
