A Library of Batted Ball Stats
February 15, 2006
(Almost) every player for the last four years.
I’ve posted a lot of batted ball tables on this blog. Up to now, I’ve hesitated to just “dump” them all on the Internet because I just don’t believe in “data dumps.” The tables are kind of confusing and need to be interpreted carefully.
However, this is really cool data, and I think the table format works pretty well (thanks to comments from readers of this blog). So, the heck with it. I’ve posted the batted ball tables of every major leaguer who saw a decent chunk of time last year. You can start with the Batted Ball Index, which includes an index of all teams and a player search button.
I’ve also added some tips regarding how to read the tables. So please look them over and leave any comments or questions you might have about the stats on this blog. And spread the word—I hope that I didn’t do all this work in vain!
Regarding correlation, there is a full article about that in the Hardball Times Annual. In general, correlations for both frequency and net run values are much higher for batters than pitchers. The exact correlations for pitchers, however, is still a good topic of research. As you say, you have to control for a number of things.
For pitchers in general, frequency of outfield flies and groundballs is strong, but line drive frequency is fairly weak (different analyses I’ve seen have ranged from 0 to .3). The run values have much lower correlations than frequency stats.

I found a smaller minor error. Jimmy Rollins’ stats appear to be listed twice on the Philadelphia page.

Ah, and I missed Kenny Lofton. Thanks, Trev. I fixed it.
