I noticed that too...and there may be some plausible explanation(s).Parallax, or more accurately motion parallax (Greek: παραλλαγή (parallagé) = alteration) is the change of angular position of two stationary points relative to each other as seen by an observer, caused by the motion of an observer. Simply put, it is the apparent shift of an object against a background caused by a change in observer position. If there is no parallax between two objects then they are side by side at the exact same height.
Keep in mind that this may have been influencing this height and weight disparity as well...Parallax error. Precise parallax measurements of distance usually have an associated error. Thus a parallax may be described as some angle ± some angle-error. However this "± angle-error" will not translate directly into a ± error for the range, except for relatively small errors. The reason for this is that an error toward a smaller angle results in a greater error in distance than an error toward a larger angle.
However an approximation of the distance error can be computed by means of the following:
where d is the distance and p is the parallax. The approximation is far more accurate for relatively small values of the parallax error when compared to the parallax.
Now with all of that said...my guess is the height and weight disparity that we witnessed after the game on the mound was more influenced by these factors... To gain that much desired stature...
...for shedding those unwanted and unnecessary pounds.
