VISTA JUNE PR - How Does OSA Stack Up? Infographic Series vol. 1

The quality of OSA ratings is often the topic of discussion. 

I've personally found that when it comes to superstars, they are generally correct. It's the youngins that they can be off on. I am going to make charts for a variety of ratings and the corresponding statistics. Contact rating vs BA is the first one. The next will be ISO vs power rating.

For contact vs BA, the contact rating provided by OSA does seem to hold some weight but just about every rating has a pretty wide range. But there is a little clutter around the line I drew from the lowest and highest contact rated players (Javier Deleon and Jeff Daniels - I used 300 ABs for this by the way).

The widest range was at the 11 contact level. Frederico Hernandez of Orlando has .285 avg while his teammate Jose Perez seems to be blinking as the ball approaches the plate with a .182 avg. 

The 17 contact rating level was the most interesting to me. Paul Mullins is near the line but slightly below. The 3 players above the line are all clustered together about .40 points above.

16 contact rating seemed to have the most even distribution through it's range with only 2 guys on top of each other (heh heh heh).

JImmy Vickers of Greenville seems to be outperforming his contact rating the most Jose Perez of Orlando the least. 

Of the 82 players in this study, there are 30  who fall below the line without touching it.

14 who touch the line and then 38 who are above it. 

I will also revisit this at the end of the season to see if it gets even tighter or stays around the same.
