I've been trying to figure out why Jurjjens was able to drop 1.08 from his ERA between two seasons ago and last season. Everything looks about the same other than a 40 point drop in BABIP. I'm not huge on stats, but I know that BABIP is generally viewed as a measure of luck. What confuses me is that while the BABIP was lower, there wasn't a big change in total hits. Can anyone help me understand this?
More broadly, can JJ be consistently as good as he has been these last two years given his peripherals? He seems like an outlier to me.
