Pitchers have a few special requirements when it comes to their gloves. They don’t have a lot of padding, they’re usually larger than infielders gloves, and the larger surface area allows pitchers to disguise their hand placement around the ball. All in all, you want your pitcher’s glove to be as comfortable and lightweight as possible.
Pitchers can usually use any kind of infield glove. Since the pitcher is trying to deceive the batter, it helps to have a closed web on the glove so that he or she can hide the ball and hand grip from the batter.
Baseball rules permit a pitcher's glove to be up to 12 inches in size, of any weight or color except white or grey, as long as it is not distracting.
Pitchers' gloves are designed to conceal the seams on the ball they throw, and tend to be lighter than a fielder's mitt.
Most pitchers use a glove 11 ¾” to 12”, but some prefer a slightly smaller or larger one. A glove this size is large enough to hide your grips and still allow you to pitch with ease.
A pitcher can wear a batting glove as long as it is not on their pitching hand.
A pitcher usually uses a standard infield glove. A closed web on the glove hides the ball from the batter, which aids the pitcher in deceiving him.
