From MLB.com
The STRIKE ZONE is that area over home plate the upper limit of which is a horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants, and the lower level is a line at the hallow beneath the knee cap. The Strike Zone shall be determined from the batter's stance as the batter is prepared to swing at a pitched ball. (For diagram of STRIKE ZONE see page 23.)
Would you not define the horizontal line as referenced above to be roughly at the armpit level??? Give or take an inch...
At the bottom of the page listed below is a picture for reference.
