Abstract
A synthetic grass sport surface (10) suited for use in a baseball field includes an infill layer (16) of particulate material evenly spread among rows of ribbons (14) extending upwardly from a backing mat (12). The infill layer (16) includes a top covering sub-layer (26) of non-marking material, such as recycled rubber used in the manufacture of soles for running shoes. A checkered pattern of alternating color tones is formed on the synthetic grass surface (16) for improving the natural appearance thereof. The synthetic grass surface also includes a synthetic grass warning track (34) having different tangible properties to alert a player stepping thereon that he is approaching an obstacle.
