MLB Stats with ADI and VMI


Here, you can query any “active” hitter with an MLB history to match his primary hitting stats from MLB with the VMI and the ADI.  First, select the league and the team, then the player.  If the player is on IR, then he will not show on the active roster, but his data will be available when he returns to the roster. 

If he is on the active roster, you will see his recent production graphed against the Air Density similar to that which you see when he is one of your member roster selections.  

Below the first graph (for comparison purposes) is the same graph of his production compared to the VMI. 

You can modify the data shown to match-up with the ADI and VMI by selecting the box at the column heading and click on the Modify Button.  Also, on the column headings you can choose to see an additional number of games in his history (including while playing for other teams), or all games within our database, by selecting the Games Box and drop down list. 

What is the PVMI?


You may want to compare the data to the PVMI.  The PVMI is the Personal Visual Memory Index.  For those who are everyday players, the VMI and the PVMI will be mostly the same.  However, when an everyday player misses a game--or in the case of an injury, is out of the lineup for an extended period--his PVMI will be different from the team’s until he has played in enough games to match the team.  Sometimes, this extends to traded players, as well.  The PVMI does not take into account potential hitting that may have been done in a batting cage during inactive status.  

For utility players (who don't play every day) the PVMI will normally be different from the team VMI because the PVMI is based on the most recent games actually played, whereas the VMI reflects the team's most recent games.
