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.

Gio Gonzalez-  The Adi of 66.47 looks great tonight for Gio Gonzalez who has been great lately.  When you mix in the Marlins team VMI of -3.74 it’s a great indication that he should be on his game tonight even against Stanton who crushes LHP.

Sean Newcomb –Just like we mentioned yesterday it takes a few games for these teams to settle in after leaving Coors.  The Phillies still have a team VMI around -11.00 today so factor in that with how bad they’ve been and I love Newcomb tonight.

Brandon Woodruff – The Twins see a decent drop down in Team VMI tonight so I like Woodruff in this spot.  We all know that the Twins have been struggling so this is another matchup I’d have interest in tonight.

Top Teams to use for hitting per ADI/VMI

Very few options tonight

• Arizona Diamondbacks- Similar to yesterday the Diamondbacks have a team VMI of 4.40 and the conditions at Chase make them a great play if you want to against the grain and fade Alex Wood tonight.

• Atlanta Braves – It’s hard to trust the Braves right now because they haven’t been hitting but the conditions in Atlanta say when they do they should go off. Its SUPER hot and humid compared to most parks so we need to consider them tonight again.
