Many leagues prohit a pitcher from wearing anything white that is not part of the uniform (for example white undersleves are prohibited). There are also other rules like prohiting glove strings that are too long, distracting jewelry etc.

Good answer Sidd!

Yes They do because It is distracting, the only reason they wont let you wear a white glove is because it is the same color of the ball and might get mixed up to the batter.

ya u arent aloud to wear anything on ur arms or any extras i think it is a dumb rule cause i have been called out for that alot before
