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.

Jacob Faria-  Last night on the WiseTake podcast we loved him and looking at Milwaukee’s team VMI of -4.32 and the ADI of 66.84 inside of Tropicana Field just locked him into my lineups tonight.  Faria has everything going for him tonight so he’s viable in all formats.

Yu Darvish – I’ll make this quick and simple, the Mets have a TERRIBLE team VMI of -16.59 and we all know teams struggle after Coors which is what this number represents.  Love tons of Darvish tonight in all formats.

Madison Bumgarner– Madbum profiles great as far as ADI/VMI tonight but he is more of a GPP play for me if you have interest in him.  Arizona has a team VMI of -6.66 and the ADI in SF is 68.19 which is the best on the slate but SF usually is.  There’s a few guys that have decent BvP off Madison but he can definitely do well tonight against the D-Backs who we all know struggle on the road.

Top Teams to use for hitting per ADI/VMI

• Phils/Rockies- We all the deal by now, Coors is listed first for a reason.  The ADI is always attractive and with both the pitchers going I love both teams tonight.  The total should easily go above 12 so please have some exposure.

• Oakland Athletics– I think this is a sneaky team to stack tonight and I mentioned that last night on the podcast. The A’s come in with a team VMI of +4.64 against a bad pitcher and with a Coors slate I don’t expect many people to be on them tonight.

• Minnesota Twins – After the way the Twins have been playing I can completely understand people not wanting to roster them tonight. However, they do have a decent bump in VMI tonight at +2.05 and I wouldn’t expect many people to have any interest in them tonight
