Air Density Report w/ @Syracuseeee – 8.2.17

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

Brent Suter –  Today Suter will face the Cardinal with a team VMI of -2.11 which doesn’t sound bad but it’s the 2nd worst on the slate today in a better than average ADI of 63.74

Jason Vargas – Although I hate using any pitcher against the Orioles right now they come into today with the worst team VMI on the slate at -2.25.  The conditions will be above average tonight in Baltimore with a ADI of 63.29

Luke Weaver – If you watched this kid itch in his debut last week the results didn’t show how well he pitched.  If it wasn’t for a JD Martinez grand Slam he would of shut down the Diamondbacks.  The Brewers that strikeout a lot have a team VMI of -1.45 so consider Weaver tonight if you’re running multiple lineups

 

Top Teams to use for hitting per ADI/VMI

  • Mets/Rockies- Its Coors and both teams have team VMI’s over 11

 

  • Seattle Mariners- Team VMI of +2.20 and it should be very warm in Texas tonight with a ADI of 59.79

 

  • Braves/Dodgers- I think both teams are in play here. The ADI in ATL tonight will be 59.51 and both pitchers aren’t very good so load up on the bats from this game
