Welcome to Unique Sports!
Infield Style Screens serve many different purposes. They can be used to protect various fielders during infield drills, they can be used as a make shift L screen if one doesn't exist, and can be used as a backstop. The Champro Infield Screens come in two sizes, 7 foot by 7 foot and 10 foot by 10 foot.
As you get into older ages and are using all of the field at one time for multiple drills, an infield screen is a must have to protect players. If there are not infield screens in place, the risk of a stray ball hitting another player increases significantly. No one wants to lose a player to injury from that! Plus these can double as a portable backstop if needed.
