Every baseball used in a game today was stitched by hand. Not by a machine. By a person. The 108 stitches aren't just tradition, they create the surface friction that makes a curveball curve, a fastball rise, and a slider cut. Change the seam height by a millimeter and you change the entire pitch. Same spec. Since 1872. Every USSSA sanctioned ball meets that same standard. Did you know this?
