Bases Contributed by 2015 Texas Rangers

This post is exploring an often overlooked statistic in baseball:  base-runner movement following plate appearance in MLB.  Since this data isn't tracked well in the stat sheet, we would have to check the play-by-play.  My source was www.retrosheet.org, which included play-by-play info for all American League Games at the time of data collection with little to no work required (just figuring out how to use the DOS prompt to slice the raw data into the play-by-play appropriately).

When in doubt, root for the home team, so here's the figure for all Texas Rangers with >400 plate appearances in American League Ballparks (due to data limitations of retrosheet).  You might think of "Personal" bases as "from home" as they are all bases to which this player advances himself.  As I didn't want to overthink it, I used plate appearance (PA), rather than at-bats as the denominator so advancement would includes hits, walks and sacrifice situations.

I may work up some additional teams, once I have a more robust statistic developed, as I would like something that factors in both offense (total bases per PA) and defense (total bases allowed per PA).  Still, if you've got a request for a team, post it in the comments section below.
