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.
When a hitter puts the ball in play, the major league average to get a hit is only slightly above .300.  The upper tier of hitters can average around .340, which is how they manage to consistently hit above .300 year in and year out.  What this number means is that a ball hit in fair territory (many swings do not hit the ball fair) has nearly a 70% chance of being an out.  This is where the walk comes into play.  Hitters who are patient enough to work counts and take pitches are much more susceptible to walks than those who chase every first pitch.  The odds of reaching base after taking 4 balls is obviously 100%.  Essentially, hitters must be lucky in order to get a hit, while drawing a walk guarantees them to reach base.  This is why the walk is such a vital part of baseball overlooked by many. 
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.
For small numbers of at-bats, it is possible (though unlikely) for a player's on-base percentage to be lower than his batting average (H/AB). This happens when a player has almost no walks or times hit by pitch, with a higher number of sacrifice flies (e.g. if a player has 2 hits in 6 at-bats plus a sacrifice fly, his batting average would be .333, but his on-base percentage would be .286). The player who experienced this phenomenon with the most number of at-bats over a full season was Ernie Bowman. In 1963, with over 125 at-bats, Bowman had a batting average of .184 and an on-base percentage of .181.
You just need to look at some of the players hitting between .280 and .285 to see the validity in Correa's point: Boston Red Sox second baseman Dustin Pedroia, Cardinals third baseman Matt Carpenter, Cincinnati Reds third baseman Todd Frazier, San Francisco Giants right fielder Hunter Pence, Milwaukee Brewers center fielder Carlos Gomez and Baltimore Orioles center fielder Adam Jones qualify for the new .300. Every one of them was an All-Star this year.
In baseball, the batting average (BA) is defined by the number of hits divided by at bats. It is usually reported to three decimal places and pronounced as if it were multiplied by 1,000: a player with a batting average of .300 is "batting three-hundred." A point (or percentage point) is understood to be .001 . If necessary to break ties, batting averages could be taken to more than three decimal places.

On the strength of a batting average of thirty-three point nought seven for Middlesex, he had been engaged by the astute musical-comedy impresario to whom the idea first occurred that, if you have got to have young men to chant 'We are merry and gay, tra-la, for this is Bohemia,' in the Artists' Ball scene, you might just as well have young men whose names are known to the public.
HR/FB% – This stands for home run to fly ball rate, which is the percentage of fly balls a player hits that end up as home runs. While this stat doesn’t play much of a role in BABIP due to the fact that home runs are factored out of the BABIP equation, it is definitely a key component of a player’s batted ball profile. HR/FB% is a stat that is largely skill based, but typically doesn’t see much fluctuation from year-to-year, so a player that posts a HR/FB% much lower than their career norm is very likely to bounce back the following season and vice versa.
OBP was a big leap forward ten or twenty years ago because it gave credit to hitters who reached base via walk or HBP when batting average ignored those things. Any time you don’t make an out, you’re contributing positively to the run scoring process and OBP captures that better than batting average because it incorporates a big slice of offensive activity that batting average doesn’t consider. Getting on base via walk doesn’t help your team quite as much as getting a hit, but it’s certainly valuable enough to warrant inclusion in even the most simplistic metrics.

There’s a very good chance that you’ve heard these phrases at some point, “that was effortless” or “kid’s got easy power”. If you’re unfamiliar with “effortless power” you might not understand what I mean. Simply put it means that a hitter will display great power  but visually it doesn’t look like they tried to swing hard. Perhaps the more scientific way to describe and “effortless swing” would be, efficient.
Here are our nine candidates for best primary offensive stat -- and please note that every offensive stat here is very important, we're just trying to pick which is the top dog. Also note, categories such as doubles, triples and stolen bases are clearly important but couldn't be rationally argued as the most important stat. Thus, they were left out. - Matt Snyder
On base plus Slugging (OPS): Somewhere, half way between traditional statistics and sabermetrics is what Fox sportscaster Joe Buck called "that new OPS statistic." Yes, he actually said that, during the 2011 World Series broadcast. (Notice that I resist the strong temptation to go off on a rant tangent, here, in an effort to stay on topic.) On base plus slugging, or OPS, is just that. Take a player’s on base percentage and add his slugging percentage, and voila, you get OPS. Now, I think that OPS is a very useful statistic ... for sluggers. But it’s still very much a slugger’s stat. OPS gives one base for walks, two for a single, three for a double, four for a triple, and five for a home run. We’re used to seeing OPS being discussed in conversations now when discussing the MVP awards for each league and it's commonly used in baseball discussions these days.
The longest delays probably involve the nerve cells that make the decision to swing. These decision-making cells receive their input from the eye by way of the brain's visual cortex. It takes at least 43 thousandths of a second for information about the velocity and trajectory of the baseball to be sent from the retina to the higher visual cortex. What happens during the actual "decision" is a neurological mystery — but once the decision is made, a signal is sent to the cerebellum initiating a series of pre-programmed, reflex-like actions (for a practiced batter).
Runs scored (R): Aside from when a player hits a home run, he'll need some help from teammates -- most of the time -- to score a run. Still, players can do a lot to increase the number of times they score. Getting on base frequently, stealing bases, taking extra bases on singles or doubles, taking a base on a passed ball right in front of the catcher or even being such a scary baserunner to draw a balk are ways to spin around the bases better than others. Guys who score the most runs are great players, not those simply lucky to have good teammates driving them in. Here are the top 10 all-time in runs scored: Rickey Henderson, Ty Cobb, Barry Bonds, Hank Aaron, Babe Ruth, Pete Rose, Willie Mays, Cap Anson, Stan Musial and Alex Rodriguez. Marginalize that group at your peril. - Snyder
Explosive Hips are crucial to power hitting. They are also the most overlooked and underdeveloped group of muscles. They are typically extremely tight and weak. The two best things you can do to “unlock” your power in your hips; a comprehensive mobility routine and exercises that involve your hips. I like exercise that involve these two skills in one movement; lateral lunges and single leg split squats are two exercises that create mobility in the hips and are powerful movements.
As the hitter has recognized pitch height, they will then use the separation between their pelvis and shoulders and much like a rubber band, “snap” into a violent rotation of their body. This immediate energy creation will transfer up the body and into the arms and hands which will then allow the barrel to flail or turn around the hands and knob. Whatever the hitter’s top barrel speed is, the goal should always be to get there as soon as possible. Just like a sprinter off the blocks, gaining top speed in the shortest amount of time is crucial to facing faster pitching.
In baseball statistics, on-base percentage (OBP) is a measure of how often a batter reaches base for any reason other than a fielding error, fielder's choice, dropped or uncaught third strike, fielder's obstruction, or catcher's interference. OBP is calculated in Major League Baseball (MLB) by dividing the sum of hits, walks, and times hit by a pitch by the sum of at-bats, walks, times hit by pitch and sacrifice flies.[1] A hitter with a .400 on-base percentage is considered to be great[2] and rare;[3] only 55 players in MLB history with at least 3,000 career plate appearances (PA) have maintained such an OBP. Left fielder Ted Williams, who played 19 seasons for the Boston Red Sox, has the highest career on-base percentage, .4817, in MLB history.[4] Williams led the American League (AL) in on-base percentage in twelve seasons, the most such seasons for any player in the major leagues.[4][5] Barry Bonds led the National League (NL) in ten seasons, a NL record.[5][6] Williams also posted the then-highest single-season on-base percentage of .5528 in 1941, a record that stood for 61 years until Bonds broke it with a .5817 OBP in 2002.[7] Bonds broke his own record in 2004, setting the current single-season mark of .6094.[7]
I'm an agnostic when it comes to a silver bullet statistic. Sure, it might exist somewhere, but I haven't seen evidence to support that. Instead, I think the sheer number and variety of statistics we have show just how much beauty and nuance there is in the game, and why it's the greatest game that's ever been. That said, I like OPS+ because it incorporates many different things -- getting on base (i.e. not making outs) and slugging, while also putting those performances into the context of a time (the season) and place (ballaparks). I also like the simplicity of 100 being average -- so if you see something like Barry Bonds' run of four years with a 230 or better OPS+ is simply superhuman (or some may say, unnatural).
"Look at it like this: If you have a team with average offense, average defense, average pitching, it should get about 81 wins," Correa says. "What that average means is different, depending on the context. There are lots of theories as to why offense is down, but the reality is that somebody hitting .260 with a .320 on-base percentage and .400 slugging is actually an above-average player today.
