GrandSlam
A baseball and softball system tuned for the physics of the ball. Dense, low-pile surface for predictable roll, true bounce, and a clean slide. Combined monofilament and parallel-fibrillated fibers interlock at the canopy to reduce infill flyout. The aesthetics of the most meticulously maintained natural grass surface. Available in a two-color configuration.
GrandSlam is built for ball roll and bounce. The dual-fiber system pairs monofilament with parallel-fibrillated slit film at low pile, tuned for infield, outfield, and warning track. The same operators run this line as run Predator.

A baseball field is not a football field with bases drawn on it.
GrandSlam is engineered for the ball, not the cleat. The combined monofilament and parallel-fibrillated build delivers a dense, low-pile canopy that returns a true bounce, holds infill against ball spin, and reads the slide of an infielder the way a manicured natural-grass surface does. Different fiber configurations are available for infield, outfield, and skin areas.
Monofilament
The blade fiber. Monofilament polyethylene cut to a low pile so the ball reads off the canopy the way it reads off a manicured infield. Holds upright between groundballs and recovers between drag-net cycles.
Parallel-fibrillated
The lock fiber. Parallel-fibrillated yarn knits with the monofilament at the canopy and traps infill in place. Less flyout under cleat impact and ball spin. The two-color option lives here, giving programs the contrasting infield arc or outfield band.

What sports is GrandSlam built for?
Baseball and softball. GrandSlam is the dedicated infield-and-outfield system tuned for predictable ball roll, true bounce off the carpet, and clean slide pattern.
The dense, low-pile profile is what separates a baseball-grade synthetic turf from a multi-sport football field that has been re-marked for diamond use.
How does the fiber blend reduce infill flyout?
GrandSlam interlocks a monofilament with a parallel-fibrillated fiber. The two profiles knit at the canopy and trap infill in place under cleat impact and ball spin. Less flyout, less re-topdressing, fewer trips to the maintenance shed during a long season.
Does GrandSlam come in two colors?
Yes. The two-color configuration is available for programs that want a contrasting infield arc, dirt-cutout shaping, or a darker-tone outfield to match a parent club's identity. The two-color option does not change the underlying performance spec.
How does it differ from GrandSlam Extreme?
GrandSlam is the base baseball/softball system. GrandSlam Extreme adds the extreme-cycle backing for higher-traffic D1 and pro-affiliated programs and supports the optional NaturalCool heat-mitigation infill.
Per-spec ball performance is comparable. Per-warranty performance favors the Extreme build on programs running daily practice plus a full home schedule.
Where is GrandSlam manufactured?
All GrandSlam fibers are extruded at the Sprinturf plant in Dadeville, Alabama. Tufting and coating happen at the Sprinturf plant in Chatsworth, Georgia. Sprinturf is the only North American synthetic turf company that owns extrusion through tufting through coating in-house.
What is the warranty?
GrandSlam carries an 8-year limited warranty against fiber failure, seam separation, and excessive color fade. As of 2026, Sprinturf has not had a fiber failure on a warranted field since 2010.
Buying through Sourcewell, OMNIA, BuyBoard, or TIPS-USA?
GrandSlam is on every contract. Most school districts and parks departments can piggyback an existing co-op contract and skip a full RFP.
