Late 19th Century – Early 1900s: Primitive Protection

In baseball’s early days, field protection was rudimentary at best. Groundskeepers improvised with whatever materials were available, often resulting in waterlogged fields and numerous game cancellations.

• Late 1800s: Groundskeepers relied on individual canvas sheets to protect only the most critical areas – the pitcher’s mound and home plate. These heavy covers required multiple staff members to deploy and often caused more damage to the turf when dragged across the field.
• Early 1900s: Some innovative ballparks experimented with multiple connected canvas segments, attempting to cover larger portions of the infield. These patchwork solutions provided inconsistent protection and were cumbersome to deploy.
• 1920s era: As baseball’s popularity grew, so did the need for more reliable field protection. Groundskeepers developed creative solutions using available materials, though no standardized approach existed. Some teams used old circus tents cut into sections, while others relied on wagon covers repurposed for baseball use.
• Depression era: Economic hardships limited investment in field maintenance technology, but teams began coordinated efforts to protect entire infield areas. These methods remained labor-intensive, often requiring 15-20 groundskeepers to deploy effectively.

During these early decades, rain protection was inconsistent at best. Teams frequently played in muddy conditions that would be unacceptable by today’s standards. Games were regularly called off when weather deteriorated, causing significant financial losses for teams and disappointment for fans who had traveled to see their favorite players.

Mid-Century Developments: The Foundation of Modern Protection

The post-war boom brought new materials and technologies to America’s pastime, revolutionizing how fields were protected.

• War years (1940s): Material shortages during World War II limited innovation, but canvas remained the standard covering material. Some teams experimented with surplus military tarps, which offered improved water resistance but were extremely heavy and difficult to maneuver.
• Post-war period (late 1940s): The introduction of early synthetic materials began to replace canvas in forward-thinking ballparks. These new materials reduced weight by approximately 25%, making deployment less labor-intensive and storage more practical.
• Mid-1950s: The first uses of single large tarps to cover an entire infield appeared in Major League Baseball. The Brooklyn Dodgers and New York Yankees were among the early adopters of this approach, setting a new standard for field protection.
• Late 1950s: Polyethylene emerged as the preferred material, offering dramatically improved water resistance and reduced weight. This innovation alone cut tarp weight by approximately 40%, making rapid deployment possible for the first time.

This period marked the beginning of modern field protection concepts. The post-war economic boom allowed for greater investment in stadium infrastructure, and emerging plastics technology revolutionized what was possible. Teams that invested in these new systems saw fewer postponements and were able to maintain higher-quality playing surfaces even during rainy periods.

The Modern Tarp Takes Shape: 1960s Breakthroughs

The 1960s saw baseball field protection transform from a necessity to a science, with innovations that remain fundamental to today’s approaches.

• Early 1960s: Rolled tarp storage systems were introduced, allowing for storage along foul lines without interfering with play. This innovation meant tarps could be deployed in minutes rather than the 15-20 minutes previously required.
• Mid-1960s: Major League Baseball witnessed widespread adoption of synthetic infield covers, with nearly all teams transitioning away from canvas by 1967. The superior water resistance and reduced maintenance costs made this an easy decision for team owners.
• Late 1960s: Standard dimensions emerged (approximately 170′ x 170′) for full infield coverage, creating consistency across ballparks. These standardized sizes also allowed for more efficient manufacturing, reducing costs for teams at all levels of play.
• Turn of the decade: Reinforced edges and pull handles became standard features, improving deployment speed and reducing tears. These seemingly small additions significantly extended tarp lifespan, providing better return on investment for teams.

The rolled tarp system was particularly revolutionary, transforming what had been a cumbersome process into a relatively quick operation. Television broadcasts now had to contend with much shorter rain delays, keeping viewers engaged and advertisers satisfied. Games could resume much sooner after rain stopped, greatly reducing delays and postponements that had plagued the game for generations.

Refinement and Technique: The 1970s Artistry

What began as pure utility now developed elements of spectacle and technique, as grounds crews perfected the art of field protection.

• Early to mid-1970s: Tarp deployment techniques became formalized by groundskeeping professionals, with crews developing coordinated approaches that resembled choreographed dances. The head groundskeeper would typically use hand signals or whistles to coordinate the team’s movements.
• Late 1970s: Introduction of air vents to prevent wind from creating dangerous billowing, after several incidents where grounds crew members were injured when trapped under wind-caught tarps. These safety innovations protected both workers and the expensive tarps themselves.
• Around this time: The first timed tarp pull competitions were held between MLB grounds crews, creating a friendly rivalry and motivating crews to perfect their technique. The Philadelphia Phillies crew, led by legendary groundskeeper Pete Lovering, set records that stood for decades.

Grounds crews became known for their speed and precision, turning tarp deployment into something of an art form that fans actually looked forward to witnessing. Teams began featuring their grounds crews in promotional materials, and some crew members became minor celebrities in their home cities. The addition of safety features like air vents prevented dangerous accidents while improving functionality.

Advanced Materials and Methods: The 1980s and 1990s Revolution

These decades saw significant technological advancements that made field protection more effective and efficient than ever before.

• Early 1980s: Lightweight polymer tarps reduced weight to under 1,500 pounds (from the 2,500+ pounds of earlier models), allowing smaller crews to manage deployment effectively. This weight reduction also meant less stress on the field when tarps were pulled into position.
• Mid-1980s: Specialized smaller tarps for pitcher’s mound and home plate became standard, providing targeted protection for the most critical areas even during brief showers. These could be deployed by just 2-3 grounds crew members in under 30 seconds.
• Late 1980s: Introduction of improved water channeling designs to direct runoff away from the infield, preventing pooling and allowing for faster field recovery after storms. These channeling systems used subtle contours and reinforced edges to control water flow.
• Early 1990s: First mechanically-assisted deployment systems tested in some stadiums, using motorized rollers to reduce strain on workers. While expensive, these systems paid for themselves through reduced injury claims and faster deployment times.

These decades saw improvements in materials science applied to field protection. The focus shifted from basic coverage to more sophisticated water management and specialized protection for critical playing areas. The weight reductions were particularly significant, making deployment safer for the grounds crew members who had previously risked back injuries and other strains during rapid tarp pulls.

Modern Era: Smart Protection for Today’s Game

Today’s field protection systems integrate cutting-edge technology with decades of practical experience, creating solutions that would have seemed like science fiction to early groundskeepers.

• Late 1990s: Ultra-lightweight materials reduced tarp weight while maintaining durability, with some models weighing less than 1,000 pounds while covering the entire infield. These materials also proved more resistant to UV damage, extending useful life.
• Early 2000s: Digital field monitoring systems began helping predict when tarps would be needed, using weather radar integrated with stadium operations systems. Some advanced systems could alert grounds crews up to 30 minutes before rainfall was expected.
• Mid-2000s: Introduction of environmentally friendly materials in tarp manufacturing, reducing the carbon footprint of field protection. These eco-friendly options quickly gained popularity as teams emphasized their environmental commitments.
• 2010s: Specialized multi-zone tarps developed for varying levels of protection across different field areas, optimizing both protection and deployment speed. These innovative designs used thicker materials in high-traffic areas while saving weight in less critical zones.
• Mid-2010s: Integration of quick-drying technology into tarp undersides to reduce field moisture after removal. These surfaces actually helped wick moisture away from the turf, dramatically reducing field recovery time.
• Late 2010s: Development of semi-automated deployment systems to reduce injury risk, using motorized assists for the heaviest portions of the tarp. These systems allowed grounds crews to maintain control while reducing physical strain.
• Early 2020s: Smart tarps with embedded sensors to monitor moisture levels and assist with deployment timing became available for high-end facilities. These systems could provide real-time data to grounds crews and management through dedicated apps.
• Recent years: Exploration of fully-automated infield protection systems in some newer stadium designs, though most facilities still rely on the expertise and judgment of experienced grounds crews for optimal results. These systems can deploy automatically when weather conditions warrant, even without staff present.

Today’s tarps represent the culmination of over a century of innovation. The focus has shifted to sustainability, worker safety, and integration with broader stadium management systems. Modern grounds crews can deploy full infield protection in under two minutes—an operation that once took dozens of workers substantially longer.

Frequently Asked Questions About Baseball Field Tarps

What size tarp do I need for my baseball field?

The appropriate size depends on the dimensions of your infield and the level of play. Standard MLB-sized tarps are typically around 170′ x 170′, but smaller fields may require less coverage. We recommend measuring your infield from the back edge of the pitcher’s mound to beyond the grass line in all directions and adding 10-15 feet for secure coverage. Our team can help you determine the perfect size for your specific field.

How many people are needed to deploy a baseball field tarp?

This depends on the size and material of your tarp. Modern lightweight tarps can be deployed by as few as 6-8 people, while older or larger models may require 10-15 people for safe and effective deployment. We recommend establishing a “tarp team” that regularly practices the procedure to ensure smooth operation when needed.

How do I properly store a field tarp when not in use?

For optimal lifespan, tarps should be completely dry before storage, folded or rolled neatly to prevent creasing, and stored in a location protected from direct sunlight and extreme temperatures. Many fields use dedicated rollers positioned along the foul lines for convenient storage and rapid deployment.

How long do quality field tarps typically last?

With proper care and maintenance, premium weighted tarps should last 7-10 years in average conditions. Factors affecting lifespan include frequency of use, exposure to UV radiation, storage practices, and deployment technique. Our weighted vinyl tarps feature reinforced edges and UV protection to maximize durability and investment value.

Are field tarps difficult to maintain?

Modern field tarps require minimal maintenance compared to their historical counterparts. Regular inspections for tears or damage, proper cleaning with mild soap and water when necessary, and correct storage practices are the key requirements. We recommend a thorough inspection at the beginning and end of each season.

What’s the difference between weighted tarps and traditional tarps?

Weighted tarps feature built-in weight systems along the perimeter, eliminating the need for sandbags or other external weights. This design allows for faster deployment, more secure coverage during windy conditions, and reduced risk of field damage. Our premium weighted tarps can save valuable minutes during sudden weather changes while providing superior protection.

Understanding Tarp Materials: Weight, Quality, and Price Considerations

When selecting the right field tarp for your program, understanding the relationship between material weight, quality, and price is essential for making a smart investment. This knowledge can help you balance immediate budget constraints with long-term value.

Material Weight: The Foundation of Tarp Quality

Tarp material weight is typically measured in ounces per square yard (oz/sq yd) and ranges from lightweight 6 oz options to heavy-duty 18 oz professional-grade materials. This weight specification is the single most important factor in determining both price and durability.

Weight Category	Weight Range	Typical Applications	Expected Lifespan
Lightweight	6-8 oz	Youth fields, occasional use	2-3 years
Medium-duty	10-14 oz	High school, collegiate fields	4-6 years
Heavy-duty	15-18 oz	Professional fields, extreme weather regions	7-10+ years

The weight directly impacts several critical performance factors:

• Durability: Heavier materials resist tearing and punctures better than lighter alternatives
• Water resistance: Thicker materials provide superior protection against heavy rainfall
• UV resistance: Higher-quality materials include better UV inhibitors, reducing sun damage
• Wind resistance: Heavier tarps are less likely to billow or lift during windy conditions
• Deployment difficulty: Lighter tarps are easier to deploy but offer less protection

How Material Weight Affects Pricing

Tarp pricing follows a relatively predictable formula based primarily on material weight and size. Here’s what drives the cost:

1. Raw material costs: Heavier tarps require more raw material per square foot
2. Manufacturing complexity: Thicker materials require specialized equipment and processes
3. Reinforcement features: Higher-end tarps include reinforced edges, corners, and handle points
4. Treatment processes: Premium tarps undergo additional treatments for UV protection, mildew resistance, and color stability
5. Warranty coverage: Extended warranties typically accompany heavier, premium tarps

As a general rule, expect a 14-16 oz premium tarp to cost approximately 40-60% more than an 8-10 oz economy option of the same size. However, when factoring in the extended lifespan, the premium option often provides better long-term value despite the higher initial investment.

How to Choose: Balancing Budget, Performance, and Longevity

Making the right choice requires honestly assessing your specific needs and constraints:

Consider Your Usage Pattern:

• Frequency of use: Programs in rainy regions that deploy tarps 30+ times per season should invest in heavier materials
• Staff availability: If you have limited grounds crew personnel, lighter tarps may be necessary despite durability tradeoffs
• Storage conditions: Programs with excellent covered storage can sometimes extend the life of lighter tarps

Evaluate Your Climate:

• Rainfall intensity: Regions with heavy downpours benefit significantly from heavier tarps with better water channeling
• Wind exposure: Open fields with limited wind protection require heavier materials with superior wind resistance
• UV exposure: Southern regions with intense sunlight should prioritize UV protection in their tarp material

Balance Your Budget Realistically:

• Initial vs. lifetime cost: Calculate the annual cost by dividing the purchase price by expected years of service
• Replacement logistics: Consider not just the replacement cost but the administrative burden of frequent replacements
• Field repair costs: Factor in potential infield damage repair costs from inadequate protection

At Baseball Tips, we generally recommend:

• Youth programs: 10-12 oz material with reinforced handling points
• High school programs: 12-14 oz material with perimeter reinforcement
• College programs: 14-16 oz professional-grade material
• Professional/municipal fields: 16-18 oz premium material with maximum reinforcement

Remember that a quality tarp is an investment in your entire field. The cost difference between economy and premium options is often recovered through reduced field repair expenses and fewer game cancellations in just one or two seasons.
