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).
On-base percentage, or OBP, measures the frequency with which a batter reaches base. OBP is expressed as a decimal rounded to three places, as in .300. Thus, OBP looks like batting average. However, instead of expressing the number of hits per at-bat, OBP represents the number of times on base per opportunity. The formula is simple, and one needs just five basic counting statistics to calculate OBP. These five stats are hits, walks, hit-by-pitch, at-bats, and sacrifice flies. The formula is:
The first of those numbers represents batting average. While most fans know about this stat, I’ll touch on it briefly just to make sure that I have all of my bases covered (baseball pun intended). Batting average is calculated by dividing a player’s total number of hits by their total number of at bats, which gives you a number that tells you how often (on average) that player gets a hit.
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.
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.
Power development for batting performance can be improved drastically through proper strength and power training. It is not to be trained through these ridiculous imitations of sport specific movement such as adding resistance bands or tubing to your bat and taking swings against the resistance of these tubes. I’ve also seen implements being attached to cable systems while mimicking swing patterns as well.

"Graham," you're probably thinking, "I know the rules of baseball. Why is this relevant?" Well, teams that are better at avoiding outs score more runs than teams that make outs frequently. This is intuitive when you think about it. For one, when a player doesn't make an out, he reaches base. At the simplest level, scoring runs is a function of reaching base and advancing runners. A player who reaches bases also hasn't used one of those precious 27 outs, thus giving batters behind him the opportunity to advance him and others around the bases. This is why sacrifice bunts do not make sense in several situations. It is rarely a good idea to attempt to use an out. We look at OBP in order to determine which hitters and teams reach base with regularity, and thus preserve a team's outs.

The third and final number in a slash line represents slugging percentage. This number is very similar to batting average, but instead of treating all hits as equals, it weighs each type of hit according to its significance. Slugging percentage (or SLG) is calculated by adding singles, 2 X doubles, 3 X triples, and 4 X home runs all divided by at bats. Another way of looking at it is total bases divided by at bats. Here is the official formula that is used:
Brian Dozier is another low average players the batting average purists love to hate.  He hit .242, but the rest of his numbers were superior to most players at second.  We complained about his average but nobody took into account that he walked 89 times and scored 112 runs.  If you’re going to count all those extra runs he scored because of the walks you should count the walks as well, and that’s something batting average doesn’t do.  While looking for a comparable player to Dozier, one interesting names came up.  Look at these two batting lines.

While watching a New York Mets game early this season, before one plate appearance the broadcast graphics displayed that catcher John Buck had a batting average (AVG) of .400 and an on-base percentage (OBP) of .396. Several games later I saw a similar phenomenon for Buck, whose OBP was again several points lower than his AVG. (In other words, the stats presented were very likely to be actual and not an on-screen typo.)

```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.

Batting average (AVG): Right off the bat, we've got to say that batting average is not the best stat to judge offense. There's too many things wrong, starting with the fact that there are a lot of variables involved such as not including walks, or the subjective nature of awarding hits and errors. Still, what batting average does have over all the other statistics is history and context. We all know what a .300 hitter is, we know how bad a .200 hitter is and how great a .400 hitter is. We still celebrate the batting crown, and although not as much as we once did, it still means something and probably should. -- C. Trent Rosecrans
```While hitting for a high batting average does not exclude hitting for power, the most successful batters with the highest averages are very good at situational hitting. This means that they can identify gaps in defensive coverage or anticipate pitches better, giving them more of an advantage at the plate. A typical player with a high batting average is patient at the plate and can hit the ball effectively to both sides of the field.
