Recall that we can use the batter's OBP, the pitcher's OBP, and the league OBP to find an expected OBP for a given matchup using the odds ratio. Since gOBP is still a proportion, we can use it to perform the same analysis. To determine which is more accurate, we first group the batters and pitchers into bins with width five points (.005). We then find an expected OBP for all pitchers and batters in that bin, and compare this to the actual results of those matchups. As an example, consider the first pair in our database: David Aardsma and Bobby Abreu, who faced each other once in 2010.
First compare the names on the left to the ones on the right.  Notice anything?  With the exception of Buster Posey, did you draft any player from the left side before any player on the right?  OK there is Dexter Fowler, but there are always a few exceptions with any example.  The players on the right are the superior players, Matt Carpenter included.  While he didn’t live up to expectations, Carpenter did score 99 runs.  The only players to score more runs from either list all come from the right side, Bautista and Trout.  Denard Span was 10th in the league in scoring runs (like I said, an exception to every rule) but the next highest player from the left side is Howie Kendrick down at #30.  Everyone else on the left had 81 or fewer runs scored where everyone on the right scored more than 81 times except Hanley and Fowler (who both had under 450 at bats due to injuries).

He has Major League time at every infield position, and has played every position on the field professionally except for catcher. Where is he now? After 16 years of playing professionally, he is now a professional scout with the Colorado Rockies. You should click to watch this great defensive play by Bernier
Recently, Indonesia’s island of Sulawesi was hit by a tsunami following a series of devastating earthquakes, affecting more than 1.5 million people. Our partner, Direct Relief, is working hard to supply Indonesia with much needed medical aid and supplies in response.

In Phase 2, the hitter may continue to accelerate but hopefully has already reached top speed.  They will maintain top speed as they continue to rotate their hips and shoulders. Contact can be made in Phase 2 before Phase 3 is ever needed. This is demonstrated when players like Mike Trout will maintain bent arms well past contact on inside pitches. If Phase 1 and Phase 2 are executed at a high level, theoretically Phase 3 is not needed.

The human ability to estimate trajectories of moving objects is difficult to explain. Good fielders begin their movement just as the ball is hit, without wasting even half a step. An outfielder instantly begins running toward the spot where he thinks the ball will fall. Sometimes, he will make a running catch without losing a stride, thrusting his glove into position at the last second.
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.
The hitter will start in their natural stance and hold the bat up against their body, shown above. Beginning the drill in this position will force the body to stay parallel to the pitcher, while placing emphasis on the hitter’s hips and torso explosiveness. See the image below of Hitting Vault coach Alexa Peterson, notice the rotation of her upper body and the position of the lower half. Her back is completely turned, knob of the bat pointing toward the pitcher and stiff front side. By rotating your hips and torso like you would in a normal swing during this drill, it will start to build muscle memory in full rotation to and through the ball.

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.


BAA is very common in evaluating pitchers -- especially when assessing opponent handed-ness splits. A pitcher cannot have an ERA against left-handed hitters because they are interspersed with righties in lineups. So when a pitcher's ability against hitters from each side of the plate is being compared, it is usually done by using either BAA or OPS-against.
