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
Mike Clevinger- The Coors Hangover is all I need to say. We get a little taste in the Early slate today but I would expect the Tigers to struggle in both games with the bats. This is the first time all year a team has had a double header after leaving Coors so we shall see. The Tigers have a team VMI of -22.67 and the conditions in Detroit are great for pitching today.
Blake Snell –Snell is my guy tonight, he has been fire his last two times out. The White Sox just suck and have a team VMI of -3.68 and strikeout much more than earlier in the season. The conditions will be great today for pitching in Chicago with a ADI of 67.00 and strong winds blowing in.
Luis Castillo – As mentioned last night on the Podcast his price was a little too high for me but after looking at the whole picture I agree with Goudsabb’s take last night. This game is AMAZING for pitching today, both teams have negative VMI’s and the ADI is very high because of the low temps. I prefer Castillo in this spot but I have no issues if you want to roster Cole.
Top Teams to use for hitting per ADI/VMI
- ARI vs COL- Coors!!!!!!!!!!!!!!!!!!!
- Texas Rangers – It was only a week ago that the Rangers roughed up Skaggs and I think we get a replay tonight as they have a team VMI of +4.89 and the Conditions in Texas look great for hitting with a ADI of 60.18
- Miami Marlins – In a perfect world the love for the Marlins will be low after stinking it up last night. The facts are they are one of the few teams with a positive team VMI of +2.23 and the conditions tonight in Miami are perfect for the long ball. One of the few spots with a high temp and high humidity so I like this spot for the Marlins tonight.
