I think it's worth pointing out that most speed guys (at least base stealing threat ones) tend to have a higher babip, and Escobar typically hasn't. The top 31 guys last year in stealing bases (last 2 were tied so I included both) had an average babip of .328 (that's just a dirty average, not scaled to playing time), and the average for all guys with at least 20 steals was .319
His 2012 appears to be a little babip fueled, but it's not like it was some unearthly number. Some of his other years may have been as much bad luck as 2012 was good luck.
