Pitch vs VMI Stats

The Sortable Stats page allows you to query our VMI database to generate pitch performance by VMI Range.  Unlike the MLB top 50, the Pitch vs VMI Stats shows the teams' season stats to date regardless of the player.  This display reveals the various VMI's in type-of-pitch categories, by date, by month or accumulated totals for individual teams and also the league totals from all teams.  It calculates and displays by pitch-type averages.

The team averages (by pitch-type) will vary slightly from Official MLB averages since Pitch Averages are generated by considering all 'hit' opportunities.  Pitches thrown in sacrifice and eventual walk situations are considered within the pitches seen by the hitter within the particular VMI Range.  There is no category for all pitch types within this display and there is no need for a VMI category as all VMI ranges are visible within the display. 

The VMI Interval

The Interval query can be changed to show more minute category separations in ball movement.  The default interval is 5.00 which allows almost a full inch of fastball movement between categories.  A 3.00 interval between VMI categories equals approximately 1/2 inch of fastball movement.  The smaller the interval, the smaller the ball movement differences from what the hitter and pitcher are accustomed to playing within.  As stated in other places within the website; all other pitches will have a similar "percentage" of movement change from what the hitter deems customary due to the air resistance at game time at the stadium. 

Pitch-Type Hit Averages

Keep in mind that each game is played in only one VMI range for a particular team.  Therefore, each pitch-type is thrown within the same VMI range.  When the four-seam fastball is most effective, the pitcher will most likely stay with it longer.  Since each pitch is designed to set up the hitter for a subsequent pitch, then for example; when the four-seamer is more effective, the two-seamer may be less effective than its counterpart, due to the tail-off as opposed to the lift.   However, some pitches may be more effective at the same time the four-seamer is effective due to the set-up. 

At Bats

When you select the number of "At Bats" for a query, be especially observant as to the probable number of at bats within your selected VMI range.  Some teams seldom play above 10 VMI, either positive or negative.  Selecting the -30 to +30 range will cover all VMI Ranges.  Any VMI above 15 plus or minus, will be associated with Coors Field in Denver, CO. 


*Wherever MLB does not show the pitch-type, speed, or result within the published play-by-play, those pitches are unaccounted for.  If changes are made by Official MLB personnel after game day; those changes may not be reflected within this display.

**Intentional walks are not included in pitch-type.
