Sensorimotor variables have been shown to predict performance in professional baseball players. However, cardinal gaze speed in baseball players has received only limited attention. This study tested the hypothesis that the cardinal gaze speed in Major League Baseball (MLB) players would be faster than in amateur prospects and non-athletes.

Seventeen MLB athletes, 160 amateur prospects, and 128 non-athletes were tested using an eye-tracking test (i.e., the RightEye CGP test) designed to measure cardinal gaze speed.

MLB players had significantly faster cardinal gaze speed than either amateur prospects or non-athletes. Moreover, there were significant differences in cardinal gaze speed across different directions. Conclusions
This was the first study to examine the speed of gaze in the cardinal positions in an athletic context. The results highlight the significant difference in cardinal gaze speed between MLB players, amateur prospects, and non-athletes.
