I think people are confusing Curb Ball and Stoop Ball….Stoop ball was played against a stoop of someones house and we also played with fielders. Catch it on a fly and you’re out! Past the sidewalk on one bounce was a single, past grass a double etc. Curb ball was much the same but played ONLY against the curb while we were in the street…and there were bases that u had to run! There was no running involved in stoop ball…Dee (The Bronx)
