The term 'Infield Cover, For Short' is a four-letter acronym for the word 'TARP'. TARP stands for 'Temporary Airfield Repair Patch', which is a type of material used to repair airfields. It is made of a strong, durable fabric that is resistant to wear and tear, and can be used to patch up any holes or cracks in the surface of an airfield. TARP is often used to cover the infield of a baseball field, providing a safe and level playing surface for the players.
