Batters in professional baseball are confronted with pitches that appear to curve, dip, wobble, or rise. The rising fastball is a pitch where the ball appears to hop up as much as a third of a meter with a sudden increase in speed. Physics experiments confirm that many reported trajectories are possible, but not the rising fastball. The present paper shows how the apparent rise may be explained as a perceptual illusion due to the hitter underestimating original speed of the pitch.
职业棒球比赛中的击球手会面对看起来会弯曲、下沉、摆动或上升的投球。快速直球是一种球看起来会突然加速向上跳跃多达三分之一米的投球。物理实验证实，许多报告的轨迹是可能的，但快速直球的轨迹不可能。本文展示了这种明显的上升如何可以解释为击球手低估了投球的原始速度而产生的一种感知错觉。
