Friction relates to baseball in many ways. For example, when the player slides into the plates, this is an example of sliding friction. Most of the time, the outfielders are standing still. This is an example of static friction. When the ball rolls down the field after a ground ball, this is an example of rolling friction, because it is rolling on the ground. When a ball is hit in the air, it is an example of fluid friction. This is an example of fluid friction because the ball is being carried in the air. Overall, baseball has many examples of friction.
