The conclusion of the GIIB article shows that team gOBP has a correlation coefficient of 0.95 with R/G, a slight but meaningful improvement over the correlation coefficient of 0.93 between team OBP and R/G. This first test is straightforward: using Retrosheet, I collected team R/G, OBP, and gOBP for all 1,482 team seasons dating back to 1955. I then fit a linear model to these data and computed the correlation coefficients for each pairing. The results are below.
Major League Baseball hitters are commonly judged based on their batting average, homeruns, and runs batted in (RBI). Those are statistics familiar to most fans, although they only tell a very small part of the story. Another important statistic is On Base Percentage (OBP). It shows how often a batter reaches base safely, whereas batting average only considers hits.
Runs batted in (RBI): It's one of the most familiar and comfortable offensive stats around, and it's still got plenty of advocates. It's one of my least favorites, not only because of its native weaknesses but also because of its outsized importance when it comes to awards, bar-stool debates and the like. The primary problem with RBI is that it's highly, highly team-dependent. After all, it's hard to drive in many runs unless runners are getting on base in front of you, and that's not something you can control. Additionally, it's highly dependent upon your spot in the lineup. Take the exact same two hitters, put one in the leadoff spot and one at clean-up and you're going to get vastly different RBI totals. Like any traditional counting stat it's useful at the margins (e.g., it's hard to drive in 130 runs and somehow suck, but it's entirely possible to plate 100 runs and not be a useful player). Mostly, if you feel compelled to pay attention to RBI, don't do so without also paying attention to RBI percentage, or the percentage of runners than a batter plated. You can't consider RBI without also considering opportunities for RBI. - Perry
Fossil evidence indicates that early humans hunted and ate other animals, and this seems to suggest that our catching and throwing capabilities may well be rooted in our development as hunters and tool users. Hitting or catching a moving animal requires an ability to estimate its path in advance. These are the basic skills required for every game of catch and throw, but for our ancestors, they may have been requirements for survival.

Why should we use OBP? What advantage does it possess over batting average? The primary benefit of OBP is that it measures a player's performance with regards to avoiding outs. Baseball does not have a clock like so many other sports. Rather, baseball teams operate under the constraint of 27 outs. Once a team has used all 27 of its outs, then the game is over.
This new formula, which they referred to as gOBP, both credits the batter for reaching on errors and penalizes the batter for sacrifice bunts. They argue first, that any baserunner gives his team a chance to score, regardless how he reached base; second, that the batter can influence whether a batted ball becomes an error*; and third, that if HBPs (which are basically mistakes by the pitcher) are counted as positive events in OBP, then errors (mistakes by the fielders) should as well. To support these arguments, they show that team gOBP correlates better with runs per game (R/G) than the traditional team OBP.
During the entire middle portion of the pitch, the batter must time the ball and decide where to swing. If the batter decides to swing, he must start when the ball is approximately 25 to 30 feet in front of the plate. The ball will arrive at the plate about 250 thousandths of a second later -- about the limit of human reaction time. The bat must make contact with the ball within an even smaller time range: A few thousandths of a second error in timing will result in a foul ball. Position is important, too. Hitting the ball only a few millimeters too high or too low results in a fly ball or a grounder.
Getting on base is an important skill, so you want to use OBP to determine if the player in question is a good offensive performer. However, OBP can only take you so far and it should only be used in the context of other statistics because OBP weights every time you reach base equally, whether you hit a home run or an infield single. If used in conjunction with slugging percentage or isolated slugging percentage, OBP is a very useful tool. In general, something like wOBA or wRC+ will tell a more accurate story, but if you’re looking for something extremely simple OBP is a much better bet than batting average.

Staying connected to the body's rotational energy starts when the hitter steps into the batter's box to prepare the launch position. To acquire a powerful launch position, the batter's upper body and shoulders must rotate to a fully loaded position. An inward turn of the upper torso and shoulders stretches the muscles of the upper body and pelvic region. Some refer to this as loading. With good transfer mechanics, the contraction of these muscles combined with the energy of hip rotation is converted into angular acceleration of the bat-head. The video below shows, and discusses, a powerful launch position.

Mickey Cochrane is the only catcher and Arky Vaughan is the only shortstop with a career mark of at least .400.[8][9] Of the 43 players eligible for the Baseball Hall of Fame with a career on-base percentage of .400 or higher, 27 have been elected. Players are eligible for the Hall of Fame if they have played at least 10 major league seasons, have been either retired for five seasons or deceased for six months, and have not been banned from MLB.[10] These requirements leave 6 living players ineligible who have played in the past 5 seasons; 5 players (Bill Joyce, Ferris Fain, Jake Stenzel, Bill Lange, and George Selkirk) who did not play 10 seasons in MLB; and Shoeless Joe Jackson, who was banned for his role in the Black Sox Scandal.[11]
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 Part 1, we'll take a look at the method to the madness of on base percentage (OBP) and slugging percentage (SLG) and see if we can give them their due respect on the scale of importance. In part 2, we'll explore why wOBA is a better stat to use than OPS and produce a scale so we can easily see what wOBA is above or below average and how the Tigers' players fit in.

Adjusted OPS-plus (OPS+): You might be familiar with OPS, which is simply on-base percentage added to slugging percentage (forget, for the moment, that they have different denominators). OPS+ is simply OPS adjusted for park and league conditions. It's scaled to 100, which means that 100 indicates a league-average OPS adjusted for park and league. An OPS+ of 110, for instance, is an OPS that's 10 percent better than the league average. On the other end, an OPS+ of 85 is one that's 15 percent worse than the league average. It's useful in that you can make a thumbnail comparison between, say, a hitter in Coors Field in 2000 to one in Dodger Stadium in 1968. It helps correct for the two things that most often corrupt unadjusted stats -- home parks and eras -- and it leans on the the two most important things a hitter can do -- get on base and hit for power. - Dayn Perry

A force profile is simply a curve that is measured as you take yourself through a movement and measure the amount of resistance at each point during that movement. For example, everybody knows what a biceps curl looks like. At the bottom of the movement you have no resistance, half way through the movement (at about 90 degrees) it becomes maximally difficult, and then once you get to the top of the movement it becomes slightly easier again.
Powerful Legs that are trained through various movement patterns and skill sets. For example, you create a ton of power by super setting (performing these two exercises one after the other with little rest, then repeating) an exercise like a squat and a box hop. This combination of a strength development exercise and a plyometric exercise create explosive power.
Comparing a baseball or softball swing to a car engine is something that I do almost everyday. It’s an easy way to help kids and parents understand how the system inside the swing works. For someone who doesn’t look at hundreds of swings a day, it can be difficult to identify or help a player become a more efficient swinger of the bat. A lot of times coaches will see a result like a pop up or ground ball and associate the weak contact with lack of effort. Most of the time, this is simply not the case. In the following article I hope to help players understand the importance of not making “early mistakes” and also help coaches and parents break down the efficient swing. To do so, we will break the swing down into three phases.  The three phases are 1. Acceleration/Angle Creation, 2. Maintain, 3. Release. They are illustrated in the picture below in a Playoff home run by Francisco Lindor.
Many players make the mistake of losing the momentum of their swing as soon as they make contact with the ball. This is a mistake. You want to add as much power and momentum as possible to the ball to throw it far. In order to do so, you should continue swinging your bat even after it has hit the ball. A good way of doing this is to assume that you have to hit two other balls immediately behind the ball you are hitting. So you have to continue swinging through the entire motion before stopping. Continued swinging adds extra power to your hit, essentially adding a ‘pushing’ momentum to it apart from the hitting force that you put into it.
Batting Average (AVG): In the beginning. If you google the term "batting champion," you will come up with the hitter in each league that has the highest batting average, and has at least 502 plate appearances for the season. That player will be declared the "batting champion" in each league. Miguel Cabrera is the batting champion in the American League, but that doesn’t necessarily make him the league’s most productive hitter. Batting average measures the percentage of time that a hitter gets a base hit. Walks don’t count, and home runs count the same as an infield single. By the way, Cabrera also led the league in on base, on base, on base.

The conclusion of the GIIB article shows that team gOBP has a correlation coefficient of 0.95 with R/G, a slight but meaningful improvement over the correlation coefficient of 0.93 between team OBP and R/G. This first test is straightforward: using Retrosheet, I collected team R/G, OBP, and gOBP for all 1,482 team seasons dating back to 1955. I then fit a linear model to these data and computed the correlation coefficients for each pairing. The results are below.

Hudson came back from Tommy John surgery in '14 as a relief pitcher so all his batting stats (minus one K in '15) come from his first six seasons. Nevertheless, they're good numbers. In 2011 he won the Silver Slugger Award for pitchers thanks to his .277 batting average with three doubles, one home run and 14 RBI in 65 at-bats, plus three walks. He's now a reliever for the Pirates so probably won't get many at-bats this season.

As stated, to hit a baseball with power, the batter's swing must stay connected to the powerful muscle groups. However, far too many batters are taught mechanics that use the arms rather than rotation to initiate the acceleration of the hands and bat. Using the arms to fire the hands ahead of rotation disconnects the swing from the larger muscles and hitting with maximum power is lost.
Without a doubt, batting average is important.  It shows a hitters ability to reach base on a swing, a vital part of baseball.  However, let's compare the two statistics in a more logical manner.  Every inning, there are three outs that the defense must make in order to end the inning.  On base percentage shows the odds that a hitter does not make one of these three outs.  It is calculated by counting walks as well as hits, so prolific walkers will often display a high differential between batting average and on base percentage. 
In cricket, a player's batting average is the total number of runs they have scored divided by the number of times they have been out. Since the number of runs a player scores and how often they get out are primarily measures of their own playing ability, and largely independent of their teammates, batting average is a good metric for an individual player's skill as a batter.
