Tracking the ball with your eyes: saccades, pursuit and head in the batter, what 57 studies say

In brief. Facing a fast ball, the expert batter follows it with the eyes early in flight, then often launches a predictive saccade toward the bounce or the contact point; the head carries a large share of the tracking. In the lab, tracking the ball helps predict its path, but no controlled trial shows that training the eyes alone improves hitting in games. 57 studies, updated November 3, 2026.

Hello to you, the movement professional,

Two of the best cricket batters in the world batted for David Mann's team, an eye tracker on their head, facing a machine that projected the ball through the life-size image of a bowler. Their heads turned with the ball and kept it in a constant direction: motionless eyes would have been enough to follow it. Their eyes nonetheless jumped ahead, most often twice, to the bounce point and then to the contact point, so as to be on the ball at the moment of hitting it (Mann et al., 2013).

"Keep your eye on the ball" remains the queen cue of hitting sports. It poorly describes what the best actually do, and yet the research partly proves it right. The skeptical coach will see a lab matter in this, and he is right on one point: among the controlled trials gathered here, no eyes-only exercise program improved hitting in games. We went back over 57 studies, from cricket to squash, null results included.

Tracking the ball with your eyes: smooth pursuit, predictive saccade and VOR

Smooth pursuit keeps a moving target on the fovea, the central, sharp zone of the retina; it relies on the cortical motion areas and on the cerebellum, and takes a moment to get started. Saccades shift the gaze in a jump; when the jump aims at a place the ball hasn't reached yet, the saccade is called predictive. The frontal eye field takes part in commanding both. The vestibulo-ocular reflex (VOR) turns the eyes opposite to the head to stabilize the image: if the head follows the ball, it has to be partly braked. In the studies, gaze adds up the position of the eyes in the head and that of the head: you can keep it on the ball while moving mostly the head.

Mann and colleagues recall a long-dominant idea, which they attribute notably to Bahill and LaRitz (American Scientist, 1984, absent from PubMed, not reread here): the ball would be too fast to be followed, and the batter would not be looking at it at the moment of hitting it (Mann et al., 2013). In 1988, Ripoll and Fleurance put the question in a title: what does it mean to keep one's eye on the ball (Ripoll and Fleurance, 1988)?

Cricket and baseball: the gaze sequence in the batter

In cricket, the batter sees the ball from a fast bowler for a little over half a second: he fixates the release, jumps to the bounce point, then pursues the ball for 100 to 200 ms, and a fast first saccade distinguishes good batters (Land and McLeod, 2000). Facing slow to medium balls, some pursue up to the bounce (Croft et al., 2010).

In baseball, with no bounce, the predictive saccade heads for the contact zone; the three best of the six professionals launch it later (Kishita et al., 2020a). It is timed to the rotation of the hip, not to the position of the ball (Kishita et al., 2020b): gaze is part of the swing. It also changes depending on whether the player hits or watches the ball go by (Fogt and Persson, 2017; Clutter and Fogt, 2026), which is what perception-action coupling describes.

The head follows the ball, the VOR steps back

In the batter, the head often does the largest share of the tracking. In players who watch without hitting, it accompanies the ball while the eyes move little and the VOR is partly braked (Fogt and Zimmerman, 2014). On a fast ball, its rotation accelerates late in flight while that of the eyes stays stable; Higuchi and colleagues conclude that classic exercises with saccades or wide pursuits do not reflect hitting (Higuchi et al., 2018). The table tennis player's gaze has its own article.

The head does more than orient. Deprived of eye movements by goggles, or of head movements by a neck brace, baseball players judge almost as accurately where a high ball will land, but respond later with the goggles and earlier with the neck brace: for the authors, head stability, one part of postural control, helps in judging (Bongers and Michaels, 2008). Fielders run to intercept luminous balls in the dark: the retina alone is therefore not enough, and the authors point to the vestibular system and proprioception (Oudejans et al., 1999). In 28 elite hockey players and 30 non-athletes, a head repositioning test explains 26 to 54% of the differences in eye speed at the start of a pursuit (Majcen Rosker et al., 2021).

"Keep your eye on the ball": what the cue gains, what it costs

The cue has support in the lab: following the target improves the prediction of its path and the accuracy of interception (Spering et al., 2011; de la Malla et al., 2017; Fooken et al., 2016), perhaps because the efference copy, the command for the eye movement, adds information to that of the retina. For Toole and Fogt, baseball hitters do keep their eyes on the ball at the start of the pitch (Toole and Fogt, 2021).

Up to contact, however, the cue describes the expert poorly. The end of the flight is of little use, visuomotor delay obliging, and the start counts for more (Higuchi et al., 2016; Jang, 2026), even if softball players make do with any two thirds of the flight (De Lucia and Cochran, 1985). When the interception point is known, the gaze jumps there (de la Malla et al., 2019), which a review ties to visual certainty and to the predictability of the path (Fooken et al., 2021). None of these studies tests the cue itself.

Acuity rarely limits performance: with lenses that blur vision, ten cricket batters lose interception only at +3.00 diopters against a machine, from +2.00 against fast bowlers (Mann et al., 2010a), and slight visual blur does not hinder their anticipation when they bat (Mann et al., 2010b).

Predicting the bounce: squash, tennis and virtual reality

In squash, predictive gaze movements are everywhere and precise, a sign of internal models of flight learned through experience (Hayhoe et al., 2012). In virtual reality, pre-bounce saccades adjust when the elasticity of the ball changes (Diaz et al., 2013); novices aim a few degrees above the bounce, then the head corrects horizontally, the eyes vertically (Mann et al., 2019). Watching tennis videos, experience of the game makes these saccades more accurate (Taya et al., 2013). This is predictive motor control applied to the eyes, with a function still debated: the saccade would not serve to monitor the ball in the periphery (Vater and Mann, 2023).

Oculomotor abilities and batter level: links, not causes

The better dynamic visual acuity of baseball players disappears when they are forced to fixate: it comes from how they track, not from a better reading of the image on the retina (Uchida et al., 2012). In professionals, visual tests are tied to plate selectivity (Laby et al., 2019; Burris et al., 2018), not to the level reached in a Japanese club (Hoshina et al., 2013), and very little in young players (Romero Clavijo et al., 2026). In cricket, players' basic visual functions resemble, with a few exceptions, those of everyone else, whereas eye and head movements distinguish elite batters from sub-elite ones (Fogt and Fogt, 2023). These studies are cross-sectional: does the game train these abilities, or does it retain those who had them?

Training the batter's gaze: seven trials, a single controlled transfer to games

Eye-centered programs transfer little. A digital program does no better than a double-blind placebo (Shekar et al., 2021), home saccades do not clearly separate the trained groups (Ganebnaya et al., 2025), and a preregistered pilot trial finds nothing in games, only an improvement in hitting in training (Liu et al., 2020, absent from PubMed, cited by its DOI). The gain of a college team rests on a comparison with the previous season (Clark et al., 2012), and a short letter without abstract on perceptual learning in baseball is cited without figures (Deveau et al., 2014).

The only league transfer measured against controls comes from adaptive batting training, in a virtual environment projected on a screen, where perception stays tied to the swing (Gray, 2017; Gray, 2020). Two recent virtual reality trials improve without game measurement: one adds batting with slow-motion feedback (Hayashi et al., 2026), the other trains only the perception of speed (Nasu et al., 2024). The article on virtual reality and decision-making details them.

Links between the studies

The description of expert gaze has been converging for a quarter of a century, from cricket to baseball. It nonetheless rests on small samples, sometimes two players, and on a few laboratories that replicate one another.

The batter's saccades and pursuit: what holds, what remains open

Established: the expert batter follows the ball early in flight, gets help from the head by braking the VOR, then launches predictive saccades toward the bounce or the contact; in the lab, following a target improves the prediction of its path. Debated: the function of the predictive saccade, the value of following up to contact, the origin of players' oculomotor abilities, trained by the game or selected by it. Extrapolation: that training the eyes outside the movement improves hitting in games. Nobody can promise you that saccade work will add a hit for your athlete.

One experiment would settle it: a randomized trial in experienced batters, comparing a pursuit and saccade program to an equal volume of real batting, judged on game statistics with a two-month retention. If it finds no difference, the idea that training the eyes alone improves hitting falls.

Double vision, blur, headaches: where to refer the batter

If your athlete reports double vision, blur that persists, headaches with exertion or dizziness, visual training waits. They see an ophthalmologist first, then an orthoptist in France, or an optometrist in Switzerland or the United States. LabO RNP is neither medical nor paramedical, and comes as a complement to a care pathway, never in its place. LabO RNP works with optometrists; the curriculum was built with them.

From gaze to swing: the batter's sensorimotor loop

The eyes are an entry point. What LabO RNP teaches are the sensory aspects of movement and the entire sensorimotor loop. The batter gives a tight example: his saccade is timed to the hip, his head follows the ball, his neck informs his eyes. The binocular vision pyramid ranks the visual skills, and the map of evidence in sports vision locates each family of training.

Tracking the ball with your eyes: what coaches ask

Should you keep your eyes on the ball up to contact?

On a fast ball, experts follow it early in flight, then often launch a predictive saccade toward the bounce or the contact, 80 to 220 ms before impact in professional baseball players (Kishita et al., 2020a). In two hitters, however, the gaze stays near the ball until 50 to 60 ms before its arrival (Fogt and Persson, 2017). The cue itself has not been tested.

Why does the gaze go ahead of the ball?

The delay between the eye and the movement makes the end of the flight of little use (Higuchi et al., 2016). The predictive saccade places the gaze where the ball will arrive, thanks to models learned through experience (Hayhoe et al., 2012). Its exact function remains debated (Vater and Mann, 2023).

Can the eyes alone follow a fast baseball?

Rarely. In hitters, the head carries most of the tracking and the vestibulo-ocular reflex is partly braked (Fogt and Zimmerman, 2014). Late in flight, head rotation accelerates while eye rotation stays stable (Higuchi et al., 2018).

Do saccade and pursuit exercises improve hitting?

No controlled trial gathered here shows it in games. A digital program does no better than a placebo (Shekar et al., 2021) and a pilot trial finds nothing in games (Liu et al., 2020). The only league transfer measured against controls comes from adaptive batting training in a virtual environment projected on a screen (Gray, 2017).

Do you need a vision assessment before working on a batter's gaze?

Yes, as soon as they report double vision, persistent blur, headaches with exertion or dizziness: ophthalmologist first, then orthoptist or optometrist depending on the country. LabO RNP is neither medical nor paramedical, and comes as a complement to a care pathway, never in its place.

In the expert batter, the head carries the ball and the eye goes to wait for it where the bat will meet it.
