It's an era estimator. Generally if you have a large gap between siera and era you can attribute the era to luck or a lack thereof. Generally the era will move closer to the siera over time as regression is bound to happen at some point.

some stats to explain what i'm talking about.
Season strike out rate: 27.6%
Since DL: 27.7%
season walk rate: 7.5%
since DL: 8%
ground ball: 63.1%
since DL: 67.4
hard hit rate: 23.9%
since DL: 21.8%
So if you look at all these numbers, McCullers has been the same pitcher that he was prior to his DL stint, but has just run into some weird outings.
His siera over his past 6 games is 3.04 and his era over the same games is 4.99. Siera is simlpy saying that given how he has pitched, his era should be 3, and not 5.
Also, most pitchers that induce weak contact at the rate that lance does, typically have a lower era than siera.Last edited by snappertapper; 07-23-2017, 12:48 PM.

Watching the games, my eyes tell me a different story. He hasnt looked in control or in command of a game since coming back off of the DL. Im not complaining, just making a general observation. I know he will make a tweak and be back to where he was prior to the DL. He is too competitive not to.
