Short grass infield - statistical relevance

A while ago I promised to do some number crunching on whether the short grass in the Ranger's infield has an effect on the number of errors and other types of hits given up in the ballpark.  Here are my results:

To sum it up it doesn't appear that there is much effect if any on fielding percentage and it looks like the fast turf actually cuts back infield hits.  It does this by noticably increasing the percentage of grounders that get to the outfield.  At home the rangers were a full 2.5% more likely to get a grounder through the infield, while the opponents only increased by 1%.

We already knew this but this chart also further reinforces just how bad the infield defense was this past year as the Out% when the Rangers were hitting is much higher than when they weren't.

Some caveats - There are 6-10 or so grounders that aren't accounted for in each group, dunno but if anyone really wants to know I can try to look.

All thanks to retrosheet.org fantastic site.
