ThumbPRO® Baseball Thumb Guard: Why Little League's Ban Is Putting Players at Risk
Bat sting hurts — especially for young players learning the game. That’s why more players, from youth leagues to the pros, trust the ThumbPRO® baseball thumb guard, the most advanced thumb guard for baseball and softball. But now, a controversial decision by Little League International is putting safety on the bench.
What Is a Thumb Guard in Baseball?
A thumb guard is a piece of protective gear worn on the top hand while batting. It helps reduce sting from inside pitches, protects against injury from getting jammed, and improves grip without altering swing mechanics. ThumbPRO® is made in the USA and engineered by players, for players — offering unmatched comfort and support.
Why Does Bat Sting Matter?
Bat sting happens when a ball makes contact near the hands, especially on inside pitches. It sends painful vibrations through the bat, which can cause bruising, swelling, and even long-term injury to the thumb or wrist. For young players with developing hands and mechanics, repeated sting can lead to possible injury along with unnecessary fear at the plate — and poor performance.
Using a baseball thumb guard like ThumbPRO® not only reduces that sting — it gives players the confidence to take an aggressive swing and stay focused on the pitch, not the pain. Most importantly, when players aren’t worried about getting jammed, they can relax, have fun, and truly enjoy the game they love. Confidence builds performance — and joy keeps them coming back.
Why Did Little League Ban Thumb Guards?
Recently, Little League International implemented a rule banning the use of thumb guards like ThumbPRO®. Their reasoning? That these guards constitute a bat modification. This is blatantly false. Importantly, ThumbPRO® isn’t part of the bat, is not attached to the bat, doesn’t change the bat’s weight or performance, and doesn’t provide any unfair advantage. It’s simply personal protective equipment — like a batting glove or helmet.
This decision has confused and frustrated families, coaches, and health-conscious players across the country. If pros and collegiate athletes can wear it, why not youth players who arguably need protection as well?
Why the ThumbPRO® Baseball Thumb Guard Is a Game-Changer for All Levels
ThumbPRO® is trusted by hitters at every level — from youth leagues and travel ball to high school, college and the pros. It’s worn over the batting glove, built with ergonomic design, and engineered to absorb shock from even the hardest-thrown pitches.

Do I wear ThumbPRO® over or under my batting glove?
ThumbPRO® is worn over your batting glove or directly on your hand if you don’t wear gloves.
Which hand should I wear it on?
Wear ThumbPRO® on your top hand — It can be worn on either the right or left hand, also ideal for switch hitters.

ThumbPRO® comes in three sizes to fit a range of players, from youth athletes to adults. Be sure to check our sizing guide to find the best fit for your hand.
Can ThumbPRO® be used in games and practices?
Yes, ThumbPRO® is designed for both practice and game use. While Little League has recently banned thumb guards, many, if not all, other youth leagues, travel, high school, college, and professional teams allow and encourage their use for safety.
Is ThumbPRO® used by professional players?
ThumbPRO® is trusted and used by players across college and professional baseball — not as a paid endorsement, but because it genuinely helps them stay protected at the plate. Almost every team in the league has players who use ThumbPRO® (keep your eyes peeled on the TV during games to spot our guard on the hands of the pros). ThumbPRO® was used in the 2024 World Series by a top pro.
What is a thumb guard and how does it work?
A thumb guard—like ThumbPRO®—is a lightweight, protective device worn on the batter’s top-hand thumb (the hand closest to the end of the bat). Its purpose is to shield the thumb joint and surrounding tissue from painful bat sting, impact shock, and vibration when the ball is hit. This helps prevent common issues like bruising, swelling, and overuse injuries that can affect performance and player confidence.
For youth players, thumb guards are especially important for teaching proper hand placement on the bat. Young athletes often grip the bat incorrectly or hold tension in their hands to avoid discomfort from sting. A thumb guard helps train better grip mechanics while providing the protection they need to swing with confidence.
Using a thumb guard encourages players to:
Relax their grip for better swing speed and control
Place their hands correctly on the bat handle
Avoid developing bad habits caused by fear of pain or sting
Protect growing joints and muscles during their key developmental years
From beginners to pros, thumb guards like ThumbPRO® offer the hand safety and performance benefits every hitter deserves.
Does a thumb guard like ThumbPRO® attach to the bat?
No, it does not.
Thumb guards like ThumbPRO® are worn directly on the player’s thumb, not on the bat. They are completely independent of the bat itself and do not alter, change, or attach to the bat in any way.
Despite what Little League®'s 2025 rulebook claims, thumb guards like ThumbPRO® are not bat attachments. This is a misleading classification that has caused unnecessary confusion. ThumbPRO® simply protects the player’s top-hand thumb—helping reduce sting, improve grip confidence, and promote safer swings at the plate without modifying the bat in any form.
Are thumb guards like ThumbPRO® legal in other leagues besides Little League®?
Yes.
Thumb guards have been worn by players for over 30 years and are recognized as an essential piece of hand protection for athletes of all ages and skill levels.
ThumbPRO®'s unique, ergonomic design stays securely in place on the player’s thumb and provides critical protection from bat sting and hand injuries—without interfering with grip or swing mechanics.
Thumb guards like ThumbPRO® are legal and widely accepted across most baseball and softball leagues.
Little League®’s 2025 rule is an unfortunate exception, and they have misrepresented thumb guards as bat modifications. This claim is blatantly false, as thumb guards are worn on the player’s hand, not on the bat, and have no impact on the bat’s structure or performance.
Why do players wear thumb guards like ThumbPRO®?
Players at every level of the game—from youth leagues to the pros—wear thumb guards like ThumbPRO® to protect their hands and improve their performance at the plate.
ThumbPRO® helps players:
Protect the lead hand (top-hand thumb) from painful bat sting and vibration
Reduce the risk of hand and thumb injuries caused by repeated impact
Improve grip confidence and swing mechanics
Train proper hand placement, especially important for youth players learning correct batting habits
Stay on the field longer by preventing discomfort and overuse injuries
ThumbPRO® is trusted by players of all ages because it offers effective, comfortable, and reliable hand protection—making it a must-have safety product for baseball and softball hitters everywhere.
How do I choose the right size and wear ThumbPRO® correctly?
ThumbPRO® comes in three sizes—Small, Medium, and Large—to fit players of all ages and hand sizes.
Choosing the right size is important for both comfort and effectiveness. The guard should fit snugly on your top-hand thumb, without sliding or feeling too tight.
Here’s how to wear ThumbPRO® correctly:
Identify your top hand (the hand closest to the end of the bat when you grip it).
Slide ThumbPRO® onto your thumb, over a batting glove or directly on your skin—both are acceptable.
Position it comfortably so that the protective saddle rests on the back of your thumb joint, not on your palm side.
ThumbPRO® is ambidextrous, meaning it works for both right-handed and left-handed hitters, including switch hitters who alternate batting sides.
