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.

Chris Stratton- I loved Stratton last night for many reasons but when I saw he was ranked first in my GPP Model it was an instant lock for me tonight.  Stratton will face the Brewers coming off a series at Coors.  We all know teams struggle the first 2 games after Coors and the Brewers team VMI of -23.18 is a perfect representation of that.  Let us also add how much the Brewers strike out and I’m sold on Stratton tonight.

Tyler Skaggs –Skaggs will face off against the Rangers tonight who come in with a team VMI of -8.05 which is the second worst on the slate.  The conditions in LA are very good for pitching with a 65.34 ADI so I expect Skaggs to pitch well tonight

Top Teams to use for hitting per ADI/VMI

• Seattle Mariners-  Seattle has the best team VMI today of +8.57 and they get to play in hitter friendly Atlanta.  Hitting in Atlanta will be awesome tonight as the ADI of 57.99 shows.

• Boston RedSox – The Redsox look juicy tonight and for various reasons but one of them is their team VMI of +3.40 and a ADI of 60.11 in Boston. Be sure to have some exposure to the Redsox tonight.
