Take a look at this picture: Alex Rodriguez, who has marked total batting average .299 at the point of 2014. As you can see, his head is inclined slightly, and it means his eye line is also inclined. Doesn't it adversely affect seeing a ball acutely? His high batting average is the answer of it.
Many recent distinguished hitters incline their heads in their batting stances, greater or lesser. But is there any textbook in which this head angle is explained, including the benefits of it? First of all, it seems to go against the textbook answer.
You will be mostly able to know the answer of this question from this figure.
As I mentioned in the (1) of this theme, hip joint flexion due to the iliopsoas muscle is crucial core element for making a correct batting stance. And it inevitably causes pelvis to tilt forward.
As the pelvis - the basement of spine - tilts forward, spine should also tilt forward to the same degree of the pelvis.
In this posture, if the neck stands upright, it means torso axis and neck axis doesn't consist with each other. On the other hand, inclining the neck to meet the angle of torso means making a straight axis through the upper body.
And what is worse is that if the axis isn't formed correctly because of the upright neck, the natural S-curve of spine also isn't formed correctly, or rather, it causes the "opposite-S-curve" of spine. This is a wrong posture which can lead to back pain.
