Mordecai Brown

Mordecai Peter Centennial Brown, nicknamed "Three Finger Brown" or "Miner", was an American Major League Baseball pitcher and manager during the first two decades of the 20th century. Due to a farm-machinery accident in his youth, Brown lost part of his right index finger. He later broke his middle finger, causing it to permanently bend. In that process he gained a colorful nickname. He turned this handicap into an advantage by learning how to grip a baseball in a way that resulted in an exceptional curveball, which broke radically before reaching the plate. With this technique he became one of the elite pitchers of his era.
