Brown (October 19, 1876 – February 14, 1948) lost parts of two fingers on his right hand, then became one of the most elite pitchers of his era with his three finger curveball. According to his biography, he suffered two separate injuries to his right hand. The first and most famous trauma came when he was feeding material into the farm’s feed chopper. He slipped and his hand was mangled by the knives, severing much of his index finger and damaging the others. A doctor repaired the rest of his hand as best he could. While it was still healing, the injury was further aggravated by a fall he took, which broke several finger bones. They were not re-set properly, especially the middle finger
He learned to pitch, as many children did, by aiming rocks at knot-holes on the barn wall and other wooden surfaces. Over time, with constant practice, he developed great control. As a ‘bonus’, the manner in which he had to grip the ball (see photo) resulted in an unusual amount of spin. This allowed him to throw an effective curve ball, and a deceptive fast ball and change-up. The extra topspin made it difficult for batters to connect solidly. In short, he ‘threw ground balls’ and was exceptionally effective [wiki]
