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.

That's a difference of about one error every two games. This seems insignificant, but we can use Tom Tango's run environment generation program to see what kind of effect those extra errors would have on offense. Plug in the 2013 MLB batting statistics (counting HBP as BB and ROE as hits) and the program estimates a run environment of 4.8 R/G*. But double the amount of errors, and that number jumps by half a run to 5.3 R/G.
So OBP=Runs, Billy Beane was right.  That doesn’t mean that the players on the left are bad, but they are inferior to the players on the right when it comes to scoring runs (and several other categories).  Justin Morneau had a fine season, but 17 home runs and 62 runs scored hardly make him the better fantasy player.  Lorenzo Cain stole 28 bases, but with 53 RBIs and 55 runs scored that .301 average is kind of empty, don’t you think?  So far OBP favors the better overall player.
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.
Great article! Your explanation of what it means to “relax” is definitely something all hitters struggle with, including myself. I’ve always been a “power-hitter”, but I didn’t really start hitting HRs consitently until I started putting backspin on the ball. For me at least, focusing on my swing and trying to have a backspin-promoting cut helped me RELAX and take the focus off of trying to kill the ball. I would grip the bat way too tight and pull everything, which was really frustrating. Another thing that helped me keep my hands relaxed was I started using that Pro-Hitter thumb ring that I saw pro’s like A-Gon and J Hamilton using… Again, great article! Thanks for providing more insight on something that all of us wish we could do at every at-bat haha! One can only dream…
Moving a single group of muscles may require the interaction of numerous nerve cells and involve multiple synaptic delays, as the body receives sensory information (sees the ball), processes it (makes a decision), and coordinates muscle action (swings the bat). Practice eliminates wasted time by speeding up the decision-making -- somehow the obvious mistakes and fruitless actions a novice spends time thinking about are simply ignored by the practiced player, and his brain saves the time needed to consider them. But basic reaction time due to nerve conduction and synaptic delay remains an irreducible constant of the game.
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.

These are just a few examples of the many critical factors that come into play regarding your hitting power that go outside the scope of what I can control on the gym floor. Essentially, you can do everything I tell you to do in this article to improve hitting power, but if you don’t have the proper technique to execute and express that power then your first priority is to learn proper batting technique.
But fear not! This is your crash course in advanced baseball stats, explained in plain English, so that even the most rudimentary of fans can become knowledgeable in the mysterious world of baseball analytics, or sabermetrics as it is called in the industry. Because there are so many different stats that can be covered, I’m just going to touch on the hitting stats in this article and we can save the pitching ones for another piece. So without further ado – baseball stats!
Statistical analysis to measure player performance has become so sophisticated over the last quarter century that traditional tools like batting average and earned run average have been augmented and in some cases even replaced by more encompassing measurements like on-base percentage, which became an official statistic in 1984, and the more revolutionary OPS--a term that combines a player's on-base percentage and slugging percentage.

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.

Hitting a baseball is one of the toughest skills in all of sport. The entire sequence, from the pitcher's release of the ball to the contact with the bat, happens in the blink of an eye. This quick series of events combines two of the most important skills for a baseball player: hand-eye coordination and power development. Hand-eye coordination helps the batter locate the ball during its flight and appropriately maneuver the bat. The power element is crucial for adding distance to hits and building a well-rounded batter.
The ability to accurately predict where the ball will be involves the extrapolative capacities of the brain, but these skills are not completely unique to humans. For example, relatively tiny-brained animals like frogs can spear flies on the wing with their sticky tongues. To do so, their brains must be programmed to determine when the flies are within range and which way they are moving. Dragonflies and birds of prey are able to dive on and capture small moving animals.

Equal power and equal run scoring abilities, yet using batting average, Dozier is inferior.  It doesn’t seem fair that two players of equal skills are ranked so far apart in fantasy, but player X had 31 more hits while Dozier had 31 more walks with the same results.  If you’re a numbers guy you might have guess who player X is, but for those that haven’t figured it out, it’s Anthony Rendon.  Rendon is shooting up draft boards while Dozier is left waiting until the mid-early rounds.  If there was a poster boy for using OBP over BA, it’s Dozier. 

Mike Napoli hit a career-high 34 home runs in 2016 with the Cleveland Indians, the third-most home runs in this free agent class, just agreed to a one-year deal, $8.5 million deal with the Texas Rangers in early February. The first baseman was worth just 1.0 fWAR after factoring in his base running skill (minus-5.2 runs) and defensive play (18th in DRS).
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.
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.

Outfielder Ty Cobb, whose career ended in 1928, has the highest batting average in Major League Baseball (MLB) history.[1] He batted .366 over 24 seasons, mostly with the Detroit Tigers. In addition, he won a record 11 batting titles for leading the American League in BA over the course of an entire season. He batted over .360 in 11 consecutive seasons from 1909 to 1919.[2] Rogers Hornsby has the second highest BA of all-time, at .358.[1] He won seven batting titles in the National League (NL) and has the highest NL average in a single season since 1900, when he batted .424 in 1924. He batted over .370 in six consecutive seasons.[3]
The way you hold the handle of a baseball bat determines the speed and power of your hit. If you choke up on the handle and hold the bat closer to the barrel, you are gaining bat swing speed but losing on the hitting power. If you hold closer to the bottom of the bat, you gain hitting power and momentum but lose on the speed. You should extensively practice with both methods of holding the handle and find the golden mean where you are able to swing quickly and still hit the baseball as far as possible.
Like any stat, OBP is not without its flaws. For one, OBP does not tell us how a player reached base. A home run and a walk count the same when computing OBP. Obviously, a home run is far more valuable than a walk. In addition, OBP is context neutral, meaning that a single with the bases empty and no outs counts the same as a single with the bases loaded and two outs.

"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.
