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.

Seth Lugo- The team VMI of the Philadelphia Phillies keeps saying to use the Mets pitching.  Last night they had the worst team VMI and they didn’t score a single run so with having a team VMI tonight of -5.42 I’ll be very interested in Lugo as well.

Jose Urena –The Rockies enter today with a team VMI of -4.12 and we all know they struggle on the road to score, so I think Urena is in a great spot if you’re looking for a punt play tonight.

Rodriquez – I’m usually one that love to play this guy at home because for whatever reason he pitches better at Fenway. Tonight Rodriquez gets a Yankees team that is still struggling to score and have a -1.26 team VMI tonight. I think Rodriquez has great upside tonight.

Top Teams to use for hitting per ADI/VMI

• Hou vs Texas- I love both sides of this game tonight the conditions are amazing for hitting.  The temperature in Texas tonight will be in the 90’s with a ADI of 57.38 which is what we want.  The Astros have a team VMI of +5.39 and the Rangers have a team VMI of +7.03 so this is a great time to game stack.

• Chicago Cubs – Depending on how popular the Cubs are tonight I have interest in them, they have a team VMI of +7.95 which is the best on the slate and they will be in the hitter friendly Chase Field. If the Cubs are not a popular play for tonight I will have a lot of exposure.

• Miami Marlins– The Marlins usually have an occasional game that they just go off and I think there’s a decent chance of that happening tonight. The Marlins come into tonight with a team VMI of +3.81 and face Gray who at times has struggled this year.
