Question

Quizplus · Accepted Answer

A rising fastball is not actually rising. It appears to rise because of the batter's incorrect underestimation of the speed of the pitch. The batter expects the ball to drop due to gravity, but the extra backspin on the fastball causes it to stay on a more level plane, giving the appearance of rising.
