Why are baseball players always "adjusting their package" ?..

I guess they might itch or something. Go Royals

It's the cup.

Because it's there.

I played catcher when I was in school. The jock straps that hold the cup were of pretty scratchy material and I used to get a chubby all the time. In high school, my girlfriend used to sit in the stands and when I would turn around she would open her legs to give me a peek at her blond bush which of course, complicated the situation.

Mostly to delay the game and give themselves and their teammates a breather. Also, it is comfort as a cup gets irritating being worn for a couple of hours in a hot climate.

I don't believe that it is connected to any commercial purpose.

Hadnt thought about that, but it makes sense,....

Played catcher in college. The cups require loads of adjustment. And the jock straps itch like all hell.

It is definitely the cup. They are hardly what I'd call roomy. I can't say that I have had any experience with the jock itching, but it does remind me of the scene from "Revenge of the Nerds" put pepper in the jocks of the football players.
