The cap is a statement piece in baseball and is oftentimes a part of the team uniform with the logo on the front. It's not just for looks, it's also great at keeping the sun out of a player's eyes and can keep sweat from dripping into their faces. Though it's often seen in movies and by fans in the stands, in the MLB, it's actually a penalty to catch the ball in your cap. New Era baseball caps became the official cap of the MLB in 1954. You'll see New Era baseball caps on and off the field, as many people wear them for fashion.
