4. wRAA (Weighted Runs Above Average)- wRAA is based off wOBA, and attempts to calculate the number of runs a player calculates for his team each season. Zero is league-average, so a positive wRAA shows above-average performance, while a negative wRAA shows below-average performance. This is a "counting statistic" (like RBIs) so players gain more runs the more they play. Also, wRAA is league-adjusted, so it is easy to compare players from different leagues and even from different eras.

5. wRC (Weighted Runs Created)- wRC is a stat that attempts to measure how many runs a player is worth to his team a year (similar to wRAA). It is not my favorite statistic, but helps make my favorite statistic which is coming up next. Also, if wRC and wRAA sound the very similar, don't worry, you’re not going insane. The stats are very alike – they’re both based off wOBA and attempt to show offensive ability in runs – but wRAA is scaled with zero as league average, while wRC is not. For that reason, if you want to see offensive ability in runs, use wRAA.

6. wRC+ (Weighted Runs Created Plus)- In my opinion, if you want to be judging a player by his offensive performance only, and you had to pick one statistic, this would be the one I would pick. It is scaled to 100, like OPS+, and is based off wOBA, unlike OPS+, which makes it much more accurate. It measures all of the same things that wOBA does and on the correct weight, but is much easier to use because of how league average is 100 and always 100. Also, wRC+ is park and league adjusted, so you can compare players from different leagues, parks or even decades.

7. ISO (Isolated Power)- ISO is the measure of a players power, or how good he is at hitting for extra bases. It is a relatively simple formula: SLG%-BA, which removes all of the singles that are accounted for in slugging percentage. I like this stat because it shows a hitter's true power and what you can expect from him in upcoming seasons (like if his doubles start becoming home-runs). Also, in order to project future ISO numbers, you should have a sample size of at least 600 PAs. If Brett Gardner has a .550 ISO after 50 PAs, don't take it too seriously.

I'm sorry I didn't finish all of the hitting statistics, but I will post the rest of them in a day or two.
Good post. Really helpful
