Santiago has 5 games with zero runs given up. 11 games with less then 2 earned. 9 games where he gave up 4 or more.

With all the strides in sabrmetrics, I am surprised that I've never seen a companion number to the ERA, namely the variance. The ERA is a mean, and the variance would measure how far from the mean the individual games went away from that.

 

A pitcher who gave up 5 runs in 9 full innings every game would have an ERA of 5.00, but so would a pitcher who gave up 2, 4, 4,  4, 5, 5, 7, 9*. But the first guy would have a variance of 0, while the second would have a variance of 2 - buncha calculations involving squares and square roots, not tough but I'll spare ya. Of course pitchers don't go 9, so the calculation would need to be slightly more involved, but I digress.

 

The variance wouldn't tell you one was better, but would answer the question everyone wants to ask about consistency. I suppose I want a guy with an ERA above 5 to be INconsistent with a high variance, while I want the guy with an ERA below 3 to be CONsistent with a low one.

 

Then there's Skew and Kurtosis, but now I am well out of my depth.

Use Delta, a lot of their planes are empty right now!

And sitting on the apron with their lights off for another night.

I really didn't like this. (It's math) but I thought if I hit like, someone would see it and think I knew what you were talking about!

If this is true

 

It is incredibly observant of you. 

 

Almost Creepy  :)

It's unnecessary observation. Some things are legal in Oregon that aren't legal in MN.

Unnecessary but worth it's weight in Gold!!!

Given the nature of pitching, you would probably have some really interesting Skew stats.  You can't go lower than 0, but you can go to infinity in a really bad outing.  Potential for some pretty incredible distribution data, definitely non-normal.

Kepler is baseball-smart. His bunts down the third base line are meant a) to get a hit, B) to keep the bleeping shifts honest. He runs the bases with acumen. He plays right field with panache. I like the kid.

I Like typing in big font. Maybe this could become a new thing for me. 

Except us old guys who already have the Zoom at 150% or more will have to read this one word at a time.

I agree

 

Even if I don't know the meaning of panache or acumen.

I don't appreciate being talked to in a raised voice. Either yell or speak normally, not somewhere in between.

I read that as running the bases with cumin and playing right field with a paunch, which didn't make any sense at all.
