Baseball Rubbing Mud

Lena Blackburne Baseball Rubbing Mud is a brand of specially prepared mud used to prepare balls in the sport of baseball before they are put into play. Newly manufactured baseballs have a somewhat slick and glossy surface, so when new they are rubbed down with the mud to reduce the slickness and give pitchers a firmer grip and better control without damaging or discoloring the ball.[1]
