It is possible for a rising fastball to be thrown by a submarine pitcher because of the technique with which they throw the ball. Because they throw almost underhanded with their knuckles near the field surface, the batter perceives the sensation of the ball going upward because of its low starting point and flight trajectory. This is not the traditional rising fastball batters believe they see. This type of movement is similar to a rising fastball in fast-pitch softball. Left-hander Sid Fernandez was known for throwing a rising fastball from a slightly "submarine" motion.
