When you're focusing/tracking something your eyes do a different type of movement called smooth pursuit [0].
To see this in action, look around normally - notice your eyes move and then stop, taking in "still frames".
Next, look at your finger and move your finger around. Notice that your eyes smoothly follow the finger around.
When the batter is watching the ball, he is similarly tracking it.

- a_e_k 4y agoTo help the batter track the ball, MLB stadiums also have a darker, solid-color region called the "batter's eye" behind the pitcher and center field [0]. It's also why pitchers can't wear white sleeves or use white gloves (e.g., Eddie Butler getting his sleeves cut off before he pitches [1]).
