Directly behind home plate, a baseball backstop is a protective barrier, screen, or netting system. It protects spectators, cars, and adjacent property by preventing wild pitches and foul balls from leaving the field.
Common Applications
Spectator Protection: Crucial for Little League, high school, college, and professional fields.
Training Facilities: Used in batting cages and backyard training setups to allow players to hit without losing balls.
Backstop Varieties for Baseball
Baseball backstop is defensive obstacles placed behind home plate or in batting cages to prevent balls, spanning from permanent stadium chain-link constructions to portable, heavy-duty vinyl, netting, or rubber screens employed for training. Important categories include chain-link fencing with optional padding for player safety, vinyl batting cage backstops, and portable popup turtle nets.
Stadium/Field Backstops (Permanent)
Chain Link Fences: Usually used to enclose the space behind home plate, these are the most conventional and robust baseball backstop for fields.
Suspended Cable Netting Systems: These contemporary professional options use tensioned steel aircraft cables and high-impact netting (e.g., 36–96 knotted nylon) to provide high visibility while effectively preventing balls.
Padded Backstops: These are typically 2 to 4 inches thick and are installed over brick, concrete, or chain link fences to ensure player safety and provide protection against high-velocity hits.
Batting Cage Backstops (Training)
Vinyl Backstops (Backdrops): Often used in batting cages, these 22 ounce heavy-duty vinyl panels (e.g., 5′ x 8′ or 5′ x 6′) hang from the netting to stop balls and extend the life of the cage net. They usually include a target for pitching practice.
Rubber Backstops: Stronger substitutes for vinyl that provide long-lasting, heat-resistant protection.
Baffle Nets: To lessen net deterioration and boost safety, a second net layer is strung within a batting cage.
Backstops That Can Be Carried Around
Pop-Up/Turtle Backstops: These baseball backstop are light, portable netting systems, like a 16ft by 9ft one, that can be moved around easily. They are often used on fields or in backyards for training.
L-Screens: Used mainly for pitching batting practice, these screens serve as a portable backstop to safeguard the pitcher.
Options for Mounting Backstop Padding
For safety, permanent baseball backstop are often padded, with the following mounting options:
Grommet Mounted: Zip ties attach it to chain link (most affordable).
Wood-Backed: For increased durability and protection from strong winds, a wood backing with a nailer lip is fitted.
Materials Used
Modern, high-visibility baseball backstops mostly consist of high-strength, UV-stabilized netting (nylon, Dyneema, HDPE), while traditional, sturdy constructions rely on chain-link fence materials. While youth fields typically utilize conventional 36 to 42 gauge nylon or HDPE, often bolstered by steel pillars and cushioned with vinyl-covered wood, professional ballparks choose knotless Dyneema or nylon for best strength and visibility.
Nylon Netting: Often UV-stabilized and treated with varnish or latex to be waterproof, it is the most popular material for current backstops. For robust, high-impact resistance, common gauges range from 36 to 42.
Dyneema / Spectra: This is the strongest fiber commercially available, and it’s utilized in professional MLB/MiLB stadiums for its exceptional strength-to-weight ratio and remarkable durability (over 6 years).
High-Density Polyethylene (HDPE): A strong, robust mesh with long-term impact resistance capabilities.
Chain-Link Fencing: The conventional material for backstops, which is strong and long-lasting, but less visible than netting.
Safety Padding: Usually positioned on the bottom part of baseball backstop (either chain-link or netting) to safeguard players; generally constructed from high-density foam with a vinyl cover.
Common Netting Layouts
Knotted vs Knotless: Knotted is widely used for durability, whereas knotless provides a flatter surface.
Mesh Structure: Improved visibility is achieved by hanging it on the square (instead of diamond).
Reinforcement: Rope borders typically reinforce edges for more resilience and simplicity of installation.
Support Structures Backstop
- Steel Posts: Vertical poles are utilized to hang the netting.
- Cable Systems: High-tension steel wires commonly hold the netting for suspended constructions.
Padding for Backstop
- Wood Backing: Used to attach safety pads to brick or concrete walls.
- Vinyl Padding: Usually affixed to the bottom of the chain link for safety.
