Also called a baseball cup, box, athletic cup - made of hard impact-resistant plastic or light metal, often with flexible sides for comfort and protection, designed to protect the testicles and groin from impact of a baseball, baseball bat, cleats, or any other moving object. Absolutely required for catchers, pitchers, and often all infielders. Many leagues require all male players to wear jockstrap and cup for practices and games.
The Wright & Ditsons Lajoie baseball bat. This bat had a normal size barrel but had two knobs on the handle. The lowest knob was at the bottom of the handle and the other knob was roughly two inches above the lowest knob. This was designed to have better spacing between the hands due to the knob being in the middle of the grip. This also gave batters an advantage when they choked up on the bat, because the second knob provided a better grip.
