Air Density Report w/ @Syracuseeee – 8.8.17

In this article I will break down the top teams and players that are affected the most by VMI and ADI today.  Many of you might ask what is VMI and ADI is so below I have written a brief description of what they mean and how they affect baseball games.

Air Density Report w/ Cuse

Visual Memory Index aka VMI in baseball is used to track how players perform under different air density’s. The easiest way to explain this is that depending on the weather temperature, humidity, or air density the batters swing will be affected.  You might ask yourself how is that possible?  Have you ever tried to swing a bat in the winter compared to a humid summer day?  It’s not the same and VMI tracks each batters muscle memory to various weather conditions.  A batter’s muscle memory takes time to adjust to certain weather conditions.  When taking VMI into effect I avoid teams or players with a number less than -5 which simply can be explained as they haven’t been hitting pitches with the type of movement that they will face on that day.  As far as what’s good for teams or players, I try and target +5 or greater because they will be used to pitches with high movement and their Visual memory will be good.

Air Density Index aka ADI is very simple to explain.  It’s a scale that goes 0-100 and is affected by three things (Elevation, temperature, and Humidity).  The Air Density is important in baseball because it will let you know how much movement the baseball will have in that ballpark on that day.  The higher the ADI the more movement on the pitch.  Typical 60 is the number people use to decide if the pitcher’s movement will be good or bad.  The lower an ADI is from 60 the less movement the pitchers ball will have and the higher it is from 60 will show the increase in the pitcher’s ball movement to the batter’s eye.

 

Todays Top Pitchers per VMI/ADI

Ariel Miranda-  The ball should be moving in Oak today with a ADI of 67.88.  The Mariners and Athletics both have terrible team VMI’s tonight so if need be I think you can consider Graveman as well.

Julio Teheran –Real scary anytime you recommend this guy for a pitcher.  The trend of using pitchers against teams leaving Coors will continue today, it’s been working so let’s keep doing it.  The Phillies have a team VMI of -14.01 which is the 2nd worst on the slate.

Corey Kluber – See above the Rockies have a team VMI of -21.09

 

Top Teams to use for hitting per ADI/VMI

  • Arizona Diamondbacks- They are juicy tonight, with a team VMI of +6.86 and love to hit at Chase Field.

 

  • Atlanta Braves – The conditions in Atlanta are always great and with the only ADI under 60 I love the Braves in this spot tonight, the dew point alone makes this game very interesting
