Air Density Report w/ @Syracuseeee – 7.28.17


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-  Miranda sparks my interest for so many reasons tonight.  The ADI in Seattle tonight will be 67.13 which is the 2nd highest on the slate.  The Mets come into the game after a series in SD with a team VMI of -2.37.  What I love about Miranda is that he profiles well against the Mets tonight.  The Mets don’t hit his pitch types that Miranda throws in high ADI’s.  Factor in Miranda’s great home splits and the Mets not hitting lefties and I’m sold on Miranda tonight.

Jaime Garcia and Daniel Gossett- I love both pitchers in this matchup, neither team profiles well and they both have below average team VMI’s.  The ADI of this game is the highest on the slate so the pitchers should benefit from the weather conditions.

Tanner Roark– Keep targeting pitchers against Colorado until their VMI is better, today they come in at -6.16


Top Teams to use for hitting per ADI/VMI

  • Baltimore Orioles- This is what I want you to do tonight, Stack the Orioles and then go out enjoy your night and when you get home count your money.  The Orioles VMI is off the chart tonight at +10.03 with a great ADI of 55.77 in Texas.  Its suppose to reach almost 100 degrees tonight so the ball will be flying out like crazy.


  • Texas Rangers- Team VMI of -3.85 and see above. If either of these teams get too chalky go with the other team.


  • Philadelphia Phillies- This is a great spot for the Phillies tonight the come in with a team VMI of +2.01 which is a big bum up from their previous game. They will get a Julio Teheran that’s been pitching better of late but tonight that changes.  I like a Phillies mini stack to pair with an expensive stack in GPP’s.
