Here at Red Reporter, some of us are more interested in statistics than others, but we've all been known to use these newer metrics. Unfortunately, we don't always take the time to explain the figures. I know that I'm frequently guilty of inserting statistics without providing an adequate illustration of their meaning. In an effort to provide context to these figures and their use, we've decided to roll out a new series of posts exploring these new metrics. We will start with the simpler statistics and work our way to others from there. You won't need a statistics or mathematics degree to understand these posts, and best of all, we'll have fun. I promise.
Those three stats (K%, BB%, BB/K) are the bulk of what is used to determine a player’s plate discipline, but there are actually quite a few more advanced stats that can be used get a much deeper look into a player’s approach at the plate. It’s really not necessary to get very in-depth with these stats, but a simple description and league context is really all you need to be able to apply them.
Well, if you go to Fangraphs.com, go to the player stats page and you click on "Advanced" (which is code for sabermetrics), you’ll see that there are several statistical categories after each player, but they are sorted according to wOBA, by default. So, perhaps wOBA is to sabermetrics what batting average once was to statisticians of the 1950s and 60s. Probably the most important measure of a player’s offensive value.
OPS stands for on base plus slugging and is exactly what it sounds like. You take a player’s OBP and add it to their SLG to get OPS. This stat is often used to measure a player’s overall ability as a hitter, combining their skill at getting on base (OBP) with their aptitude to hit for power (SLG). Sometimes it will be included at the end of a typical slash line, so if you see a slash with four different numbers in it, then OPS is what the fourth one represents.
In my opinion this must happen before acceleration so that the barrel can accelerate the appropriate direction. Depending on the the pitch height, the hitter will mirror that height with the angle of their shoulder rotation followed by the degree of the barrel. The higher the pitch, the flatter the rotation and barrel. The lower the pitch the higher the barrel will stay initially and the shoulders will the rotate more vertically. In a perfect world, the barrel level will match the shoulder level at contact.

There is a very important Biomechanical Principle that pertains to the initiation of the baseball swing. The principle states: "A ballistic motion, once initiated, produces trajectories that can only be changed at its margins." This means, the forces applied to the bat during initiation produce trajectories that will set the tone for the entire swing. If the swing is not initiated correctly - little can be done to compensate for it.
Exactly how humans are able to estimate the expected position of a quickly moving ball is unknown. Obviously, this remarkable skill is learned through long practice. Eye-brain-body coordination is acquired only by going through the motions over and over; even so, the batter misses most of the time. Getting a hit three times out of ten at bat is considered an excellent average. It's interesting that George Schaller and other ethologists have observed that lions and cheetahs are also successful only about a third of the time in capturing their prey.
“These results show that batting is a sequence of coordinated muscle activity, beginning with the hip, followed by the trunk, and terminating with the arms. Power in the swing is initiated in the hip, and therefore exercises that emphasize such strength development are indicated. The maintained, high muscle activity in the trunk muscles indicates a need for back and abdominal stabilization and rotation exercises.”

An example is the Internet Archive, which uses the term in ranking downloads. Its "batting average" indicates the correlation between views of a description page of a downloadable item, and the number of actual downloads of the item. This avoids the effect of popular downloads by volume swamping potentially more focused and useful downloads, producing an arguably more useful ranking.
