Mark Trumbo led the majors in home runs (47) last season with the Baltimore Orioles yet could only parlay that into a three-year, $37.5 million deal with the club to return for 2017. Trumbo produced 2.2 fWAR in 2016, but was a liability in the field (his minus-11 defensive runs saved ranked him 170th out of 185 outfielders) and on the base paths (cost the Orioles two runs in 2016 due to his stolen bases, caught stealings and other base running plays).

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. 

Barry Bonds, who set the record for the most home runs in a season than any other player in Major League Baseball history, is often cited as a power hitter. His career was later bogged down by issues regarding performance enhancing drugs. However, he managed a total of 762 home runs while also earning a comparatively high ISO compared to his rivals, with the publication Business Insider labeling him #3 in a list of the greatest power hitters of all time.[2]

The second number in a slash line represents on base percentage. This is calculated by dividing the total times a player gets on base (hits, walks, and hit-by-pitch) by a player’s total number of eligible at bats, essentially all trips to the plate minus events outside of the batters control, like reaching on error and hitting into a fielder’s choice). These “eligible at bats” are calculated by adding regular at bats with the total number of times walked, hit-by-pitch, and hit into a sacrifice fly. That gives you the following formula to calculate on-base percentage, or OBP for short.

LD% – This stands for line drive percentage, which is the percentage of balls a player hits that end up as line drives. As you might imagine, line drives are harder to field than any other type of batted ball, so you can expect them to fall for hits much more often. The league average on liners last year was .690, which means that you can expect a line drive to fall for a hit roughly 69% of the time. It makes perfect sense, then, that the more line drives a player hits, the higher you can expect their BABIP to be. This is supported when you compare the BABIP of players with a LD% above-league average (.313) to their counterparts with a below-league average mark (.297).
Offensive wins above replacement (oWAR): I like it because it removes the problematic portion of WAR, which is its defensive estimates. oWAR is all about contributions made at the plate and on the bases, and it measures those quite well. It's denominated in theoretical runs tied to "replacement level," which approximates the productivity of a "freely available" sort of player (e.g., the bench player, the minor-league veteran, the waiver claim). Batting, base-running and an adjustment for positional difficulty are all baked in. - Perry

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.
"It's all about having a quality at bat," said Garrido, who has won five national titles. "You can't just go up there and start swinging and expect to get hit after hit. You have to be able to separate the pitches you can hit and the pitches you can't hit. And when you find that pitch let the ball location help you decide where you want to hit it. If you can do that you are on your way."
