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:

 

Team & Location Balls in Play Grounders Outs Balls Through Infield Infield Hits Fielding Errors
Rangers in Arlington 2328 922 669 183 49 17
Rangers Elsewhere 2359 953 699 165 63 18
Opponents in Arlington 2526 1004 720 193 54 28
Opponents Elsewhere 2413 1053 754 192 73 25

 

Team & Location GB% Out% for GBs IFH% F% GB to OF%
Rangers in Arlington 39.604811 72.55965 5.31 0.975218659 19.84816
Rangers Elsewhere 40.3984739 73.34732 6.61 0.974895397 17.31375
Opponents in Arlington 39.746635 71.71315 5.38 0.962566845 19.22311
Opponents Elsewhere 43.6386241 71.60494 6.93 0.967907574 18.23362

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.
