Air Density Report w/ @Syracuseeee – 7.27.17

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

Jon Lester-  Lester will face a struggling White Sox team tonight and the ADI/VMI lines up for him too in this matchup.  On a day where theres not many options for ADI/VM he stands out as one of the best bets.  The ADI for this game is 62.35 which is a little above average and the White Sox have a team VMI of -1.96 which is a a decent bump down from yesterday’s +0.65.  If Lester brings his “A” game tonight he should pitch a gem.

NYM vs SD- I usually like to decide on a pitcher for each game but as of this morning I’m still torn on both these pitchers.  Flexen is a guy that’s pitched well in AA this year and is going up against the Padres.  On the other side, you get Perdomo who has limited upside in my opinion.  Flexen is generating a lot of talk and is the favorite to win in Vegas tonight so keep that in mind.  This game lines up as the game with the best pitching conditions with a ADI of 64.40

 

Top Teams to use for hitting per ADI/VMI

  • Cincinnati Reds- I was already interested in the Reds if you watched the WiseTake Podcast last night so when I saw their VMI of +3.52 it put an instant smile on my face.  The Reds had a nice bump up in VMI from yesterday and when you factor the pitcher they get tonight I’m sold on them for a stack.

 

  • Tampa Bay Rays- The Rays tonight have a juicy VMI of +3.68 and are facing CC Sabathia who we all know has struggled at home this year. I like all the TB right hand batters in the lineup tonight.

 

  • Ari vs STL- This is a prime spot for hitting today as the conditions will be like last night with the heat. This is the only game on the slate with an ADI below average (58.58).  The one thing I will mention is personally I prefer the Cardinals in this spot because only once this year have the D-Backs scored more than 3 runs in their first game of a series away from Chase Field.
